Description

Optical three-dimensional space converter and applications based thereon TECHNICAL FIELD

[0001] The present invention belongs to the field of optical three-dimensional imaging, and in particular to an optical three-dimensional space converter and some applications based on the optical three-dimensional space converter. BACKGROUND

[0002] Until now, the structure of optical telescopes has not changed significantly, and is still an optical system composed of a single long-focus objective lens (or a series of objective lens groups) and a single short-focus eyepiece (or a series of eyepiece groups). The object-side field of view of the telescope is generally small, and the maximum is only a few degrees (such as 4-6 degrees). In addition, the image in the telescope is only a virtual image, and there is no telescope that has seen a real image.

[0003] Similarly, the structure of optical microscopes has not changed significantly, and is still an optical system composed of a single short-focus objective lens (or a series of objective lens groups) and a single long-focus eyepiece (or a series of eyepiece groups). The object-side field of view (size or area) of the microscope is generally small. When the magnification is low (such as 4x or 10x objective lens), the object-side field of view is between a few millimeters and a few centimeters; for example, the field of view of a 10x objective lens is about 3 millimeters in diameter. When the magnification is medium (such as 20x or 40x objective lens), the object-side field of view is between a few hundred micrometers and a few millimeters; for example, the field of view of a 40x objective lens is about 500 micrometers in diameter. When the magnification is high (more than 40x), the object-side field of view is between a few tens of micrometers and a few hundred micrometers; for example, the field of view of a 100x objective lens is about 150 micrometers in diameter. In addition, the image in the microscope is only a virtual image, and there is no microscope that has seen a real image.

[0004] The camera commonly used at present can only record the two-dimensional world without the third dimension distance or depth information, and some auxiliary technologies such as ultrasonic ranging, laser radar ranging, infrared ranging, monocular structured light ranging and binocular ranging are needed to obtain the distance or depth information; the ultrasonic, laser, infrared and other devices calculate the distance between the measured object and the sensor by measuring the time difference between the emission and return of the emission source, which is called active method, the active method is convenient, rapid and simple in calculation, and therefore is widely used in real-time control. However, the emission and receiving equipment is expensive, the cost is high, and the reflection, noise, cross and other environmental problems are difficult to avoid, and it is difficult to realize large pixel, and it is still difficult to realize universal application. The monocular structured light ranging can only be used for short distance measurement, such as the development of face distance structured light ranging for improving the accuracy of face recognition; the binocular stereo vision can accurately restore the three-dimensional information of the field of view through the parallax information of the two images provided by the left and right cameras, but the binocular vision needs to match and analyze the corresponding points of the left and right images to obtain the spatial distance information, the calculation workload is large, and the binocular vision measurement is also affected by the feature point mismatching, which is difficult to meet the real-time requirement.

[0005] The stereoscope presents different visual angles to each eye through two slightly different images, producing depth and stereoscopic effect. However, modern stereoscopic film projection technology, virtual reality stereoscopic display technology and head-mounted display require wearing glasses, which is very inconvenient. Although naked-eye stereoscopic display technologies such as holographic display, multi-viewpoint display based on parallax barrier or cylindrical lens have been developed, stereoscopic display is still not the three-dimensional space display method in nature, and the cost is high and the user experience is poor.

[0059] Embodiment one: the application discloses an optical three-dimensional virtual image space converter, which is suitable for converting a large object space into a small image space, and is represented by an optical meridian plane, as shown in Figure 1, and specifically comprises: a long-focus lens serving as an objective lens, which is used for receiving light from the object side and imaging an intermediate image; a short-focus micro-lens array serving as an ocular lens, each micro-lens in the short-focus micro-lens array converts the intermediate image imaged by the long-focus lens into a virtual image in a three-dimensional virtual image space according to the spatial angle range corresponding to each micro-lens; and a relative position adjuster, which is used for adjusting the front-to-back relative position of the long-focus lens and the short-focus micro-lens array, further adjusting the reduction ratio of the space converter, and moving the relative position multiple times in the same time to complete the imaging of the space between the micro-lenses in the short-focus micro-lens array.

[0060] The long-focus lens is a long-focus lens or a long-focus lens group formed by at least two lenses in series.

[0061] The relative position adjuster can also convert the same three-dimensional object space twice or more times by adjusting the up-down and left-right relative positions, so as to make up for the insufficient optical function of the gap part not participating in imaging and the edge part of the micro-lens with poor imaging quality in the short-focus micro-lens array.

[0062] The focal planes of the micro-lenses in the short-focus micro-lens array can all coincide with the focal plane of the long-focus lens, or partially coincide and partially be on the left side of the focal plane of the long-focus lens (crossing the focal plane), or all be on the left side of the focal plane of the long-focus lens (crossing the focal plane).

[0063] The large three-dimensional object space in the object angle range from α1 to α2 (Δα = α2 - α1) is reduced to a three-dimensional virtual image space in the image angle range from β1 to β2 (Δβ = β2 - β1) by the optical three-dimensional virtual image space converter. Δα and Δβ can be equal or not equal. The reduction ratio of the object-to-image size is related to the focal length ratio F0 / fi: the larger the focal length ratio F0 / fi is, the larger the reduction ratio is. A large object angle range α can be divided into multiple small object angle ranges Δαi, and the three-dimensional object space in each Δαi is converted by the three-dimensional space converter into a three-dimensional virtual image in a small image angle range Δβi in the short-focus micro-lens. The three-dimensional virtual images in multiple small image angle ranges Δβi are combined into a three-dimensional virtual image in a large image angle range β.

[0064] In particular implementation: as shown in Figure 21: the three-dimensional virtual image space converter from large (object) space to small (image) space can be used as a telescope. The eye or observer is in the image side, observing the three-dimensional virtual image of the three-dimensional space object in the short-focus micro-lens array reduced to the front of the eye. This embodiment uses a long-focus convex lens (or convex lens group) as a long-focus lens, and a short-focus micro-concave lens array (or micro-concave lens group array) as a short-focus micro-lens array. Because the eyepiece of a general telescope has only one short-focus lens, it can only observe a small object angle range. While the eyepiece of the telescope of the present application is an array composed of a plurality of short-focus micro-concave lenses arranged side by side, each short-focus micro-lens observes a small object angle range, and a plurality of short-focus micro-lenses simultaneously observe a plurality of small object angle ranges, thereby enabling simultaneous observation of a large object angle range. Therefore, the telescope in this embodiment has a larger viewing angle range than a conventional telescope.

[0065] Embodiment two: the present application discloses an optical three-dimensional virtual image space converter, which is suitable for small (object) space to large (image), as shown in Figure 2, represented by an optical meridian plane, comprising: a short-focus micro-lens array as an objective lens, each micro-lens in the short-focus micro-lens array receives light from the object side according to the spatial angle range corresponding to each micro-lens, and images an intermediate image; a long-focus lens as an eyepiece, used to convert the intermediate image imaged by the short-focus micro-lens array into a three-dimensional virtual image of a three-dimensional virtual image space; a relative position adjuster, used to adjust the front-to-back relative position of the long-focus lens and the short-focus micro-lens array, further adjust the magnification of the three-dimensional space converter, and used to move the relative position multiple times within the same time to complete the imaging of the space between the micro-lenses of the short-focus micro-lens array.

[0066] Wherein the focal length F0 of the long-focus lens is greater than the focal length fi of each micro-lens in the short-focus micro-lens array; the number of micro-lenses of the short-focus micro-lens array is ≥ 2, and the focal length of each micro-lens in the short-focus micro-lens array can be the same or different. The focal length F0 of the long-focus lens and the focal length fi of each micro-lens in the short-focus micro-lens array are fixed focal length or variable focal length.

[0067] The long-focus lens is a long-focus lens or a long-focus lens group composed of at least 2 lenses in series. The short-focus micro-lens array is a short-focus micro-lens array or a short-focus micro-lens group array, the short-focus micro-lens array is composed of at least 2 short-focus micro-lenses arranged in parallel, the short-focus micro-lens group array is composed of at least 2 short-focus micro-lens groups arranged side by side, and the short-focus micro-lens group is composed of at least 2 micro-lenses in series.

[0068] The relative position adjuster can also convert the same three-dimensional object space twice or more times by adjusting the up-down and left-right relative positions, so as to compensate for the insufficient optical function of the gap part not participating in imaging and the edge part of the micro lens with poor imaging quality in the short-focus micro lens array.

[0069] The focal plane of each micro lens in the short-focus micro lens array can be all coincident with the focal plane of the long-focus lens, or partially coincident and partially on the left side of the focal plane of the long-focus lens (intra-focal plane intersection), or all on the left side of the focal plane of the long-focus lens (intra-focal plane intersection).

[0070] A small three-dimensional object space in the object angle range Δα from α1 to α2 is enlarged by the three-dimensional space converter shown in FIG. 2 into a three-dimensional virtual image space in the image angle range Δβ from β1 to β2. Δα and Δβ can be equal or not equal. A large object angle range α can be divided into multiple small object angle ranges Δαi. The three-dimensional object space in each Δαi is converted by the three-dimensional space converter into a three-dimensional virtual image space in a small image angle range Δβi in the short-focus micro lens. The three-dimensional virtual image spaces in multiple small image angle ranges Δβi are combined into a three-dimensional virtual image space in a large image angle range β.

[0071] In specific implementation: as shown in FIG. 22, the three-dimensional virtual image space converter from a small (object) space to a large (image) space can be used as a microscope. The eyes or observers observe the three-dimensional virtual image of the small three-dimensional object in the long-focus lens enlarged in front of the eyes. This embodiment uses a long-focus convex lens (or convex lens group) as the long-focus lens and a short-focus micro convex lens array (or micro convex lens group array) as the short-focus micro lens array to realize a virtual image microscope. Because the objective lens of a general microscope has only one short-focus lens, it can only observe a small object angle range. In this embodiment, the objective lens of the microscope is an array composed of multiple short-focus micro lenses. Each short-focus micro lens observes a small object angle range, and multiple short-focus micro lenses simultaneously observe multiple small object angle ranges, so that a large object angle range can be observed simultaneously. Therefore, this microscope has a larger viewing angle range than a conventional microscope.

[0072] Embodiment three: a scanning three-dimensional camera is disclosed based on the optical three-dimensional virtual image space converter of figure 1, which is suitable for large (object) space to small (image) space, and is represented by an optical sub-surface, as shown in figure 3. It also includes a scanning three-dimensional photoelectric conversion sensor arranged on the side of the short-focus micro-lens array. The scanning three-dimensional photoelectric conversion sensor includes a three-dimensional camera lens, a two-dimensional photosensitive sheet, and a left-right position scanner. The three-dimensional camera lens converts the three-dimensional virtual image into a three-dimensional real image for three-dimensional photographing recording. The left-right position scanner drives the two-dimensional photosensitive sheet to quickly scan and photograph the three-dimensional real image formed by the three-dimensional camera lens. The relative position adjuster is also used to adjust the relative positions of the three-dimensional camera lens, the long-focus lens, and the short-focus micro-lens array.

[0073] In specific implementation, as shown in figure 23, a long-focus convex lens (or convex lens group) is used as the long-focus lens, and a short-focus micro-convex lens array (or micro-convex lens group array) is used as the short-focus micro-lens array. The convex lens (or convex lens group) is used as the three-dimensional camera lens in the three-dimensional photoelectric conversion sensor, and the planar photosensitive sheet is used as the two-dimensional photosensitive sheet in the three-dimensional photoelectric conversion sensor. The convex lens converts the virtual image on the left side of the short-focus micro-convex lens array into a three-dimensional real image for three-dimensional photographing recording. The left-right position scanner drives the planar photosensitive sheet to quickly scan and photograph the three-dimensional real image formed by the convex lens.

[0074] The scanning three-dimensional camera can capture three-dimensional images containing depth within a larger object field angle range, and thus can be used to measure the size and distance (or depth) of real three-dimensional space objects from the observer.

[0075] Embodiment four: as shown in figure 24, unlike embodiment three, the micro-convex lens array (or micro-convex lens group array) is used as the three-dimensional camera lens in the three-dimensional photoelectric conversion sensor. The micro-convex lenses of the micro-convex lens array are arranged one-to-one on the right side of the short-focus micro-convex lens, and one-to-one convert the virtual image on the left side of the short-focus micro-convex lens into a three-dimensional real image for three-dimensional photographing recording. The left-right position scanner drives the planar photosensitive sheet to quickly scan and photograph the three-dimensional real image formed by the micro-convex lens array.

[0076] Example five: as shown in Fig. 25, unlike example three: in this example, the micro-concave mirror array (or micro-concave mirror group array) serves as the three-dimensional camera lens in the three-dimensional photoelectric conversion sensor, and the semi-transparent semi-reflective plane photosensitive sheet serves as the two-dimensional photosensitive sheet in the three-dimensional photoelectric conversion sensor. The micro-concave mirrors of the micro-concave mirror array are arranged one-to-one on the right side of the short-focus micro-convex lens, and one-to-one convert the virtual image on the left side of the short-focus micro-convex lens into a three-dimensional real image for three-dimensional photographing and recording. The left and right position scanners drive the semi-transparent semi-reflective plane photosensitive sheet to quickly scan / photograph and record the three-dimensional real image formed by the micro-concave mirror array.

[0077] Example six: the present application discloses a fixed three-dimensional photographing camera based on the optical three-dimensional virtual image space converter of Fig. 1, which is suitable for large (object) space to small (image) space, and is represented by an optical meridian plane, as shown in Fig. 4. It also includes a fixed three-dimensional photoelectric conversion sensor arranged on the side of the short-focus micro-lens array. The fixed three-dimensional photoelectric conversion sensor includes a three-dimensional camera lens and a three-dimensional photosensitive sheet. The three-dimensional camera lens converts the three-dimensional virtual image into a three-dimensional real image for three-dimensional photographing and recording. The three-dimensional photosensitive sheet photographs and records the three-dimensional real image formed by the three-dimensional camera lens. The relative position adjuster is also used to adjust the relative positions of the three-dimensional camera lens, the long-focus lens, and the short-focus micro-lens array.

[0078] In specific implementation, as shown in Fig. 26, the long-focus convex lens (or convex lens group) serves as the long-focus lens, and the short-focus micro-convex lens array (or micro-convex lens group array) serves as the short-focus micro-lens array. The micro-concave mirror array (or micro-concave mirror group array) serves as the three-dimensional camera lens in the three-dimensional photoelectric conversion sensor, and the multi-layer stereoscopic photosensitive sheet serves as the three-dimensional photosensitive sheet in the three-dimensional photoelectric conversion sensor. The multi-layer stereoscopic photosensitive sheet is stacked by a plurality of semi-transparent semi-reflective plane photosensitive sheets. The micro-concave mirrors of the micro-concave mirror array are arranged one-to-one on the right side of the short-focus micro-convex lens, and one-to-one convert the virtual image on the left side of the short-focus micro-convex lens into a three-dimensional real image for three-dimensional photographing and recording. The multi-layer stereoscopic photosensitive sheet photographs and records the three-dimensional real image formed by the micro-concave mirror array.

[0079] The fixed three-dimensional photographing camera can capture three-dimensional images containing depth within a larger object field angle range, and thus can be used to measure the size and distance (or depth) of real three-dimensional space objects from the observer.

[0088] Embodiment 13: The present application discloses an optical three-dimensional real image space converter, which is suitable for large (object) space to small (image) space, and is represented by an optical meridian plane, as shown in FIG. 11, comprising: a long-focus lens as an objective lens; an intermediate image horizontal flipper for receiving light from the object side and imaging an intermediate image; an intermediate image horizontal flipper for horizontally flipping the intermediate image imaged by the long-focus lens to become a flipped intermediate image; a short-focus micro-lens array as an ocular lens; each micro-lens in the short-focus micro-lens array converts the flipped intermediate image into a three-dimensional real image of a three-dimensional real image space according to the corresponding spatial angle range of each micro-lens; a relative position adjuster for adjusting the relative positions of the long-focus lens, the intermediate image horizontal flipper and the short-focus micro-lens array, further adjusting the reduction ratio of the three-dimensional space converter, and moving the relative positions multiple times within the same time to complete the imaging of the space between the micro-lenses of the short-focus micro-lens array.

[0089] Wherein the focal length F0 of the long-focus lens is greater than the focal length fi of each micro-lens in the short-focus micro-lens array; the number of micro-lenses in the short-focus micro-lens array is ≥ 2, and the focal lengths of each micro-lens in the short-focus micro-lens array can be the same or different. The focal length F0 of the long-focus lens and the focal length fi of each micro-lens in the short-focus micro-lens array are fixed focal lengths or variable focal lengths.

[0090] The long-focus lens is a long-focus lens or a long-focus lens group composed of at least two lenses in series. The short-focus micro-lens array is a short-focus micro-lens array or a short-focus micro-lens group array, the short-focus micro-lens array is composed of at least two short-focus micro-lenses arranged in parallel, and the short-focus micro-lens group array is composed of at least two short-focus micro-lens groups arranged side by side, and each short-focus micro-lens group is composed of at least two micro-lenses in series.

[0091] The intermediate image horizontal flipper can or can not contain an intermediate image magnification or reduction function; when containing an intermediate image magnification or reduction function, the magnification or reduction ratio is adjustable or fixed.

[0092] The relative position adjuster can also convert the same three-dimensional object space twice or more times by adjusting the front and back, left and right relative positions, to make up for the optical function deficiency of the gap part not participating in imaging and the edge part of the micro-lens with poor imaging quality in the short-focus micro-lens array; the image focal plane (left side of the short-focus micro-lens array) of each micro-lens of the short-focus micro-lens array is flipped by the focal plane of the horizontal flipper, and all coincides with the object focal plane of the long-focus lens (right side of the long-focus lens), or partially coincides + partially intersects the right side of the object focal plane of the long-focus lens (outside the focal plane), or all intersects the right side of the object focal plane of the long-focus lens (outside the focal plane).

[0093] A large three-dimensional object space from α1 to α2 in an object angle range Δα is reduced by the three-dimensional space converter to a three-dimensional real image space from β1 to β2 in an image angle range Δβ. Δα and Δβ can be equal or not equal. The reduction ratio of the object to the image is related to the focal length ratio F0 / fi. The larger the ratio F0 / fi, the larger the reduction ratio. A large object angle range α can be divided into multiple small object angle ranges Δαi. The three-dimensional object space in each Δαi is converted by the three-dimensional space converter to a three-dimensional real image in a small image angle range Δβi outside the short-focus micro-lens. The three-dimensional real images in multiple small image angle ranges Δβi are combined to form a three-dimensional real image in a large image angle range β.

[0094] In practice: As shown in FIG. 29, the three-dimensional real image space converter from a large (object) space to a small (image) space can be used as a telescope. The eyes or observers are in the image side to observe the three-dimensional real images of the far three-dimensional object space outside the short-focus micro-lens array reduced to the front. This embodiment uses a long-focus convex lens (or convex lens group) as a long-focus lens, a fan-shaped cylindrical self-focusing micro-lens array as an intermediate image horizontal inverter, and a short-focus micro-lens array (or micro-lens group array) as a short-focus micro-lens array. The intermediate image horizontal inverter here also includes the magnification function of the intermediate image, and the magnification is fixed.

[0095] Because the eyepiece of a general telescope has only one short-focus lens, it can only observe a small object angle range. However, the eyepiece of this embodiment is composed of multiple short-focus micro-lenses, each of which observes a small object angle range, and multiple short-focus micro-lenses observe multiple small object angle ranges simultaneously, thereby observing a large object angle range simultaneously. Therefore, this telescope has a larger viewing angle range than a conventional telescope. Moreover, the image of this telescope is a real image, while the image of a general telescope is generally a virtual image.

[0096] Embodiment fourteen: the present application discloses an optical three-dimensional real image space converter, which is suitable for small (object) space to large (image) space, and is represented by an optical meridian plane, as shown in FIG. 12, comprising: a short-focus micro-lens array as an objective lens, each micro-lens in the short-focus micro-lens array is used for receiving light from the object side and imaging as an intermediate image according to the spatial angle range corresponding to each micro-lens; an intermediate image horizontal flipper, which is used for horizontally flipping the intermediate image imaged by the short-focus micro-lens array to become a flipped intermediate image; a long-focus lens as an ocular lens, which is used for converting the flipped intermediate image into a three-dimensional real image of a three-dimensional real image space; a relative position adjuster, which is used for adjusting the relative position of the long-focus lens, the intermediate image horizontal flipper and the short-focus micro-lens array, further adjusting the magnification of the three-dimensional space converter, and moving the relative position multiple times in the same time to complete the imaging of the space between the micro-lenses of the short-focus micro-lens array.

[0097] The long-focus lens is a long-focus lens or a long-focus lens group composed of at least two lenses in series. The short-focus micro-lens array is a short-focus micro-lens array or a short-focus micro-lens group array, the short-focus micro-lens array is composed of at least two short-focus micro-lenses arranged in parallel, and the short-focus micro-lens group array is composed of at least two short-focus micro-lens groups arranged side by side, and the short-focus micro-lens group is composed of at least two micro-lenses in series.

[0098] The intermediate image horizontal flipper can include or not include the magnification or reduction function of the intermediate image; when including the magnification or reduction function of the intermediate image, the magnification or reduction ratio is adjustable or fixed.

[0099] The relative position adjuster can also convert the same three-dimensional object space twice or more times by adjusting the front and back, left and right relative positions, so as to make up for the insufficient optical function of the gap part not participating in imaging and the edge part of the micro-lens with poor imaging quality in the short-focus micro-lens array; the image focal plane of each micro-lens of the short-focus micro-lens array (the left side of the short-focus micro-lens array) is flipped by the focal plane of the horizontal flipper, and all or part of the image focal plane of each micro-lens of the short-focus micro-lens array is coincident with the object focal plane of the long-focus lens (the right side of the long-focus lens), or part of the image focal plane of each micro-lens of the short-focus micro-lens array is coincident with the object focal plane of the long-focus lens (focal plane outside intersection), or all of the image focal plane of each micro-lens of the short-focus micro-lens array is coincident with the object focal plane of the long-focus lens (focal plane outside intersection).

[0100] A large three-dimensional object space from α1 to α2 in the object angle range Δα is reduced by the three-dimensional space converter to a three-dimensional real image space from β1 to β2 in the image angle range Δβ. Δα and Δβ can be equal or not equal. The magnification of the object to image size is related to the focal length ratio F0 / fi. The larger the F0 / fi, the larger the magnification. A large object angle range α can be divided into multiple small object angle ranges Δαi. The three-dimensional space object in each Δαi is converted by the three-dimensional space converter into a three-dimensional real image in a small image angle range Δβi outside the short-focus micro lens. The three-dimensional real images in multiple small image angle ranges Δβi are combined into a three-dimensional real image in a large image angle range β.

[0101] In specific implementation: as shown in FIG. 30, the three-dimensional real image space converter from a small (object) space to a large (image) space can be used as a microscope. The eye or observer is in the image side to observe the magnified three-dimensional real image of the small three-dimensional space object outside the long-focus lens in front of the eye. The long-focus convex lens (or convex lens group) is used as the long-focus lens, the fan-shaped arrangement of the columnar self-focusing micro lens array is used as the intermediate image horizontal inverter, and the short-focus micro convex lens array (or micro convex lens group array) is used as the short-focus micro lens array. The intermediate image horizontal inverter here also includes the intermediate image reduction function, and the reduction ratio is fixed.

[0102] Because the objective lens of the ordinary microscope only has one short-focus lens, it can only observe a small object angle range. The objective lens of the microscope of the present application is composed of multiple short-focus micro lenses. Each short-focus micro lens observes a small object angle range, and multiple short-focus micro lenses simultaneously observe multiple small object angle ranges, so that a large object angle range can be observed simultaneously. Therefore, the microscope of the present application has a larger angle range than the conventional microscope. And the image of the microscope is a real image, while the image of the ordinary microscope is generally a virtual image.
