Description

Technical Field

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

[0002] Until now, the structure of optical telescopes has not changed significantly. They are still an optical system consisting of a single long-focus objective lens (or a series of objective lenses) and a single short-focus eyepiece (or a series of eyepieces). The object-side viewing angle of a telescope is generally small, with a maximum of only a few degrees (such as 4-6 degrees). In addition, the image in the telescope is only a virtual image, and no telescope with a real image has been seen.

[0003] Similarly, the structure of the optical microscope has not changed significantly. It is still an optical system consisting of a single short-focus objective lens (or a group of objectives in series) and a single long-focus eyepiece (or a group of eyepieces in series). The object field of view (size or area) of a microscope is generally small. At low magnifications (such as 4x or 10x objectives), the object field of view is between a few millimeters and a few centimeters; for example, the field of view of a 10x objective is about 3 mm in diameter. At medium magnifications (such as 20x or 40x objectives), the object field of view is between hundreds of microns and several millimeters; for example, the field of view of a 40x objective is about 500 microns in diameter. At high magnifications (greater than 40x), the object field of view is between tens of microns and hundreds of microns; for example, the field of view of a 100x objective is about 150 microns in diameter. In addition, the image in the microscope is only a virtual image, and no microscope with a real image has been seen yet.

[0004] The cameras commonly used at present can only record the two-dimensional world, without the third-dimensional distance or depth information. In order to obtain the distance or depth information, some auxiliary technologies are needed, such as ultrasonic ranging, laser radar ranging, infrared ranging, monocular structured light ranging and binocular ranging. 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 the active method. The active method of ranging is convenient, fast and simple to calculate, so it has been widely used in real-time control. However, the transmitting and receiving equipment is expensive and the cost is high. In addition, environmental problems such as reflection, noise and crossover are difficult to avoid. It is difficult to achieve large pixels and it is still difficult to achieve universal applicability. Monocular structured light ranging can only be used for short-distance measurement, such as the structured light ranging of face distance developed to improve the accuracy of face recognition; binocular stereo vision can restore the three-dimensional information of the field of view more accurately through the parallax information of the two images provided by the left and right cameras. However, binocular vision obtains spatial distance information and requires matching analysis of corresponding points in the left and right images, which requires a large amount of calculation workload. Binocular vision measurement is also easily affected by mismatching of feature points, making it difficult to meet real-time requirements.

[0005] Stereoscopes present different perspectives to each eye through two slightly different images, creating a sense of depth and three-dimensionality. However, modern stereoscopic film projection technology, virtual reality stereoscopic display technology, head-mounted displays, etc. all require wearing glasses, which is very inconvenient to use. Although naked-eye stereoscopic display technologies such as holographic display and multi-viewpoint display based on parallax barriers or cylindrical lenses have also been developed, stereoscopic display is still not a natural three-dimensional space display method, and it is costly and has a poor user experience.

[0071] Embodiment 1: The present invention discloses an optical three-dimensional virtual image space converter, which is suitable for converting a large (object) space to a small (image) space and is represented by an optical meridian plane, such as Figure 1 As shown, it specifically includes: a telephoto lens as an objective lens, used to receive light from the object side and form an intermediate image;

[0072] As an eyepiece, the short-focus micro-lens array converts the intermediate image formed 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;

[0073] The relative position regulator is used to adjust the front-to-back relative position of the telephoto lens and the short-focus micro-lens array, further adjust the reduction ratio of the space converter, and move the relative position multiple times at the same time to complete the imaging of the space between the micro-lenses of the short-focus micro-lens array.

[0074] The focal length F0 of the telephoto lens is greater than the focal length f of each micro-lens in the short-focus micro-lens array. i The number of microlenses in the short-focus microlens array is ≥ 2, and the focal lengths of the microlenses in the short-focus microlens array may be the same or different. The focal length F0 of the telephoto lens and the focal length f0 of each microlens in the short-focus microlens array i Fixed focal length or variable focal length.

[0075] The telephoto lens is a telephoto lens or a telephoto lens group formed by at least two lenses connected in series. The short-focus microlens array is a short-focus microlens array or a short-focus microlens group array. The short-focus microlens array is composed of at least two short-focus microlenses arranged in parallel. The short-focus microlens group array is composed of at least two short-focus microlens groups arranged in parallel. The short-focus microlens group is composed of at least two microlenses connected in series.

[0076] The relative position regulator can also convert the same three-dimensional object space twice or more by adjusting the relative positions up and down and left and right to compensate for the deficiencies in the optical functions of the gap parts in the short-focus microlens array that do not participate in imaging and the edge parts of the microlenses with poor imaging quality.

[0077] The focal planes of the microlenses of the short-focus microlens array may all overlap with the focal plane of the telephoto lens, or partially overlap and partially be on the left side of the focal plane of the telephoto lens (crossing within the focal plane), or all be on the left side of the focal plane of the telephoto lens (crossing within the focal plane).

[0078] The large three-dimensional object space within the object angle range Δα from α1 to α2 (Δα = α2-α1) is reduced to a three-dimensional virtual image space within the image angle range Δβ from β1 to β2 (Δβ = β2-β1) through the optical three-dimensional virtual image space converter. Δα and Δβ can be equal or unequal. The reduction ratio of the object to image size is related to the focal length ratio F0 / f i Related: F0 / f i The larger the object angle, the greater the reduction ratio. A large object angle range α can be divided into multiple small object angle ranges Δα i , each Δα i The three-dimensional space object in the short-focus micro lens is converted into a small image angle range Δβ by the three-dimensional space converter. i Three-dimensional virtual image within. Multiple tiny image angle ranges Δβ i The three-dimensional virtual image is merged into a three-dimensional virtual image with a large image angle range β.

[0079] When implementing: Fig.21 As shown: 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 on the image side, observing the three-dimensional virtual image of the distant three-dimensional space object in the short-focus micro-lens array that is reduced to the front of the eyes. This embodiment uses a long-focus convex lens (or a convex lens group) as a long-focus lens, and a short-focus micro-concave lens array (or a micro-concave lens group array) as a short-focus micro-lens array. Because the eyepiece of an ordinary telescope has only one short-focus lens, it can only observe a small object angle range. The eyepiece of the telescope of the present invention is an array composed of multiple short-focus micro-concave lenses arranged in parallel, each short-focus micro-lens observes a small object angle range, and multiple short-focus micro-lenses observe multiple small object angle ranges at the same time, so that a large object angle range can be observed at the same time. Therefore, the telescope in this embodiment has a larger viewing angle range than a conventional telescope.

[0080] Embodiment 2: The present invention discloses an optical three-dimensional virtual image space converter, which is suitable for converting a small (object) space into a large (image), such as Figure 2 As shown, it is represented by an optical meridian plane, including:

[0081] The short-focus microlens array as the objective lens, each microlens in the short-focus microlens array receives light from the object side according to the spatial angle range corresponding to each microlens, and forms an intermediate image;

[0082] As a telephoto lens of the eyepiece, it is used to convert the intermediate image formed by the short-focus microlens array into a three-dimensional virtual image in a three-dimensional virtual image space;

[0083] The relative position regulator is used to adjust the front-to-back relative position of the telephoto lens and the short-focus micro-lens array, further adjust the magnification of the three-dimensional space converter, and move the relative position multiple times at the same time to complete the imaging of the space between the micro-lenses of the short-focus micro-lens array.

[0084] The focal length F0 of the telephoto lens is greater than the focal length f of each micro-lens in the short-focus micro-lens array. i The number of microlenses in the short-focus microlens array is ≥ 2, and the focal lengths of the microlenses in the short-focus microlens array may be the same or different. The focal length F0 of the telephoto lens and the focal length f0 of each microlens in the short-focus microlens array i Fixed focal length or variable focal length.

[0085] The telephoto lens is a telephoto lens or a telephoto lens group formed by at least two lenses connected in series. The short-focus microlens array is a short-focus microlens array or a short-focus microlens group array. The short-focus microlens array is composed of at least two short-focus microlenses arranged in parallel. The short-focus microlens group array is composed of at least two short-focus microlens groups arranged in parallel. The short-focus microlens group is composed of at least two microlenses connected in series.

[0086] The relative position regulator can also convert the same three-dimensional object space twice or more by adjusting the relative positions up and down and left and right to compensate for the deficiencies in the optical functions of the gap parts in the short-focus microlens array that do not participate in imaging and the edge parts of the microlenses with poor imaging quality.

[0087] The focal planes of the microlenses of the short-focus microlens array may all overlap with the focal plane of the telephoto lens, or partially overlap and partially be on the left side of the focal plane of the telephoto lens (crossing within the focal plane), or all be on the left side of the focal plane of the telephoto lens (crossing within the focal plane).

[0088] From the small three-dimensional object space within the object angle range Δα from α1 to α2, through Figure 2 The three-dimensional space converter shown is magnified into a three-dimensional virtual image space within the image angle range Δβ from β1 to β2. Δα and Δβ can be equal or unequal. A large object angle range α can be divided into multiple small object angle ranges Δα i . Each Δα i The three-dimensional space object in the image is converted into a tiny image angle range Δβ in the short-focus micro lens by the three-dimensional space converter. i Three-dimensional virtual image within. Multiple tiny image angle ranges Δβ i The three-dimensional virtual image is merged into a three-dimensional virtual image with a large image angle range β.

[0089] When implementing: Fig. 22As shown, the three-dimensional virtual image space converter from small (object) space to large (image) space can be used as a microscope. The eye or observer is on the image side, observing the three-dimensional virtual image of the tiny three-dimensional space object in the telephoto lens that is magnified in front of the eyes. This embodiment is a virtual image microscope using a telephoto convex lens (or a convex lens group) as a telephoto lens and a short-focus micro-convex lens array (or a micro-convex lens group array) as a short-focus micro-lens array. Because the objective lens of an ordinary microscope has only one short-focus lens, it can only observe a small object angle range. The objective lens of the microscope in this embodiment 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 observe multiple small object angle ranges at the same time, so that a large object angle range can be observed at the same time. Therefore, this microscope has a larger viewing angle range than a conventional microscope.

[0090] Embodiment 3: The present invention discloses a method based on Figure 1 The scanning 3D camera formed by the optical 3D virtual image space converter is suitable for converting large (object) space to small (image) space and is represented by an optical meridian plane, such as Figure 3 As shown, it also includes a scanning type three-dimensional photoelectric conversion photoreceptor arranged on the side of the short-focus microlens array. The scanning type three-dimensional photoelectric conversion photoreceptor includes a three-dimensional camera lens, a two-dimensional photosensitive film and a left-right position scanner. The three-dimensional camera lens converts the virtual image of the three-dimensional space into a three-dimensional real image for three-dimensional photography and recording; the left-right position scanner drives the two-dimensional photosensitive film to quickly scan / photograph and record the three-dimensional real image formed by the three-dimensional camera lens left and right; the relative position adjuster is also used to adjust the relative positions between the three-dimensional camera lens, the telephoto lens, and the short-focus microlens array.

The left and right position scanner drives the flat photosensitive sheet to quickly scan / photograph and record the three-dimensional real image formed by the convex lens.

[0092] The scanning 3D camera can capture 3D images with a large object viewing angle and including depth, and can therefore be used to measure the size of objects in real 3D space and their distance (or depth) from an observer.

[0093] Embodiment 4: Fig.24As shown, what is different from the third embodiment is that in this embodiment, the micro-convex lens array (or micro-convex lens group array) is used as a three-dimensional camera lens in the three-dimensional photoelectric conversion photoreceptor. The micro-convex lenses of the micro-convex lens array are arranged one by one on the right side of the short-focus micro-convex lens, and the virtual image on the left side of the short-focus micro-convex lens is converted one by one into a three-dimensional real image for three-dimensional photography and recording. The left and right position scanner drives the flat photosensitive film to quickly scan / photograph and record the three-dimensional real image formed by the micro-convex lens array.

[0094] Embodiment 5: Fig.25 As shown, what is different from the third embodiment is that in this embodiment, the micro-concave mirror array (or micro-concave mirror group array) serves as a three-dimensional camera lens in the three-dimensional photoelectric conversion photoreceptor, and the semi-transparent and semi-reflective plane photosensitive film serves as a two-dimensional photosensitive film in the three-dimensional photoelectric conversion photoreceptor. The micro-concave mirrors of the micro-concave mirror array are arranged one by one on the right side of the short-focus micro-convex lens, and the virtual image on the left side of the short-focus micro-convex lens is converted into a three-dimensional real image for three-dimensional photography and recording through reflection. The left and right position scanner drives the semi-transparent and semi-reflective plane photosensitive film to quickly scan / photograph and record the three-dimensional real image formed by the micro-concave mirror array.

[0095] Embodiment 6: The present invention discloses a method based on Figure 1 The fixed three-dimensional camera formed by the optical three-dimensional virtual image space converter is suitable for converting large (object) space to small (image) space, and is represented by an optical meridian plane, such as Figure 4 As shown, it also includes a fixed three-dimensional photoelectric conversion photoreceptor arranged on the side of the short-focus microlens array, and the fixed three-dimensional photoelectric conversion photoreceptor includes a three-dimensional camera lens and a three-dimensional photosensitive film.
