[0039] In the prior art, the optical imaging system is mainly composed of a prism and two image sensors glued together, the two image sensors are directly attached to two surfaces of the prism, after the images of the two image sensors are aligned, glue is coated on the surface of the prism and the image sensor, and finally cured by UV light, which is a full attachment process. The glue filling on the surface of the image sensor and the prism is not uniform, and process quality problems such as bubbles and glue overflow frequently occur, the yield is low, and the direct-through rate is low; in addition, the image sensor directly contacts the dichroic mirror or the prism, so the temperature rise of the image sensor is first transmitted to the glue and then to the dichroic mirror or the prism, which causes large deformation of the overall structure and greatly affects the image quality obtained by the multi-image sensor optical system.

[0040] The utility model provides a kind of multi-image sensor optical system.

[0041] Please refer to Figure 1The multi-image sensor optical system 100 comprises a lens barrel 1, a connecting assembly 2, a dichroic mirror 3, a first mounting plate 4, a second mounting plate 5, a first image sensor 6 and a second image sensor 7; the lens barrel 1 has an incident end 11 and an exit end 12 in a first direction; the connecting assembly 2 is fixedly connected with the lens barrel 1, and a positioning portion 211 is arranged on the connecting assembly 2 and correspondingly arranged with the exit end 12 in the first direction; the dichroic mirror 3 is installed on the positioning portion 211 and is arranged in an inclined manner with respect to the first direction, so as to decompose light rays emitted from the exit end 12 into white light and fluorescent light and emit the light rays in the first direction and the second direction, respectively; the first mounting plate 4 and the second mounting plate 5 are both fixedly connected with the connecting assembly 2 and arranged on one side of the dichroic mirror 3 in the first direction and one side of the dichroic mirror 3 in the second direction, respectively; the first image sensor 6 and the second image sensor 7 are installed on the first mounting plate 4 and the second mounting plate 5, respectively, so as to correspondingly receive the white light and the fluorescent light, and the first image sensor 6 and the second image sensor 7 are both arranged in a spaced manner with the dichroic mirror 3.

[0042] In the technical scheme of the utility model, the lens barrel 1 is used for receiving and transmitting light rays, so that the light rays are emitted from the exit end 12 in the first direction, in order to provide a mounting reference for the dichroic mirror 3 and make the light rays emitted from the exit end 12 be able to be emitted to the dichroic mirror 3, the connecting assembly 2 is fixedly connected with the lens barrel 1, a positioning portion 211 is arranged on the connecting assembly 2 and correspondingly arranged with the exit end 12 in the first direction, and the dichroic mirror 3 is installed on the positioning portion 211; the dichroic mirror 3 replaces the prism in the prior art, decomposes the light rays and emits the light rays in the first direction and the second direction, respectively, so as to replace the prism, solve the problems of complex fixing structure, large weight and difficult size reduction of the prism, and solve the problems of low reliability and poor impact resistance of the full bonding of the image sensor (including the first image sensor 6 and the second image sensor 7) and the prism. The first image sensor 6 and the second image sensor 7 are arranged on one side of the dichroic mirror 3 in the first direction and one side of the dichroic mirror 3 in the second direction, respectively, for receiving light rays and forming images, the first image sensor 6 and the second image sensor 7 are fixedly connected with the connecting assembly 2 by the first mounting plate 4 and the second mounting plate 5, respectively, so as to realize the positioning and installation of the first image sensor 6 and the second image sensor 7, replace the adhesive connection between the image sensor and the prism (or the dichroic mirror 3), avoid the air bubbles in the glue, and solve the problems of the deformation of the glue caused by heat and the relative position relationship between the image sensor and the dichroic mirror 3. Moreover, a gap is arranged between the image sensor and the dichroic mirror 3, so as to avoid the influence of the heat of the image sensor on the dichroic mirror 3. Thus, the influence of the structure of the existing multi-image sensor optical system 100 on the image quality is improved.

[0043] In order to provide a positioning installation reference for the dichroic mirror 3 and to make it receive light and then emit light in the first direction and the second direction, the connecting assembly 2 comprises a first connecting piece 21, please refer to Figure 1 , which is fixedly connected with the lens barrel 1, and the side of the first connecting piece 21 away from the exit end 12 is obliquely arranged, and a groove 2111 is formed on the side of the first connecting piece 21 away from the exit end 12 to provide a positioning installation for the dichroic mirror 3, and the groove 2111 is one form of the positioning part 211. The included angle between the installed dichroic mirror 3 and the first direction and the second direction is equal.

[0044] In order to make the light emitted from the exit end 12 of the lens barrel 1 correspondingly irradiate on the dichroic mirror 3, the first connecting piece 21 is provided with a first light channel 212 which penetrates in the first direction, one end of the first light channel 212 corresponds to the exit end 12 in the first direction, and the other end communicates with the groove 2111; the light emitted from the exit end 12 of the lens barrel 1 irradiates on the dichroic mirror 3 through the first light channel 212, and the dichroic mirror 3 is an optical element which can separate the incident light into two different parts according to the wavelength, one part is reflected, and the other part is transmitted. Among them, the transmitted light propagates in the first direction, and the reflected light propagates in the second direction. However, the first connecting piece 21 forms an obstruction in the second direction in order to install the dichroic mirror 3, in order to avoid the propagation of light, the first connecting piece 21 is provided with a second light channel 213 which penetrates in the second direction, and the second light channel 213 communicates with the groove 2111. The reflected light enters the second image sensor 7 on the second mounting plate 5 through the second light channel 213.

[0045] In order to fix the dichroic mirror 3 and to fix the first mounting plate 4, the connecting assembly 2 is further provided with a second connecting piece 22, please refer to Figure 3 , which is arranged on the side of the first connecting piece 21 away from the lens barrel 1 and is fixedly connected with the first connecting piece 21, and the first connecting piece 21 and the second connecting piece 22 are fixed by screw connection, and the first connecting piece 21 and the second connecting piece 22 jointly clamp the dichroic mirror 3 to completely fix the dichroic mirror 3, at this time, the second connecting piece 22 is located on the side of the dichroic mirror 3 in the first direction, which hinders the propagation of the transmitted light, and the second connecting piece 22 is provided with a third light channel 221 which penetrates in the first direction, and the third light channel 221 is correspondingly arranged with the groove 2111 in the first direction. Among them, the side of the second connecting piece 22 in the first direction only partially abuts the dichroic mirror 3, which does not hinder the propagation of light.

[0046] If the first image sensor 6 and the second image sensor 7 are respectively glued on the first mounting plate 4 and the second mounting plate 5, when the first image sensor 6 and the second image sensor 7 generate heat, the glue will be deformed, so that the positions of the first image sensor 6 and the second image sensor 7 will change, and the incident light may not be perpendicular to the receiving plane of the image sensor, and the incident light may not fall on the center of the receiving plane, which will affect the quality of the received image, so in order to avoid the influence of heat on the glue, the first image sensor 6 and the second image sensor 7 are respectively fixed on the first mounting plate 4 and the second mounting plate 5 by screws, and the setting mode can keep the relative fixation with the first mounting plate 4 and the second mounting plate 5 even when the first image sensor 6 and the second image sensor 7 generate heat. In addition, if the threaded holes are pre-set on the first connecting piece 21 and the second connecting piece 22, and the first mounting plate 4 and the second mounting plate 5 are respectively fixed by screws, due to the machining error and the installation error, the incident light may not be perpendicular to the receiving plane of the image sensor, and the incident light may not fall on the center of the receiving plane, so it is necessary to adjust the slight position relationship between the connecting pieces (including the first connecting piece 21 and the second connecting piece 22) and the mounting plates (including the first mounting plate 4 and the second mounting plate 5), and then fix the connecting pieces and the mounting plates after the incident light is vertically irradiated on the center of the receiving plane of the image sensor. Since the position relationship between the connecting pieces and the mounting plates cannot be predicted in advance during the adjustment process, the connecting pieces and the mounting plates can only be glued. (The heat generated by the image sensor is limited and will not affect the glue between the connecting pieces and the mounting plates) The first mounting plate 4 is glued on the side of the second connecting piece 22 away from the lens barrel 1 in the first direction; and the second mounting plate 5 is correspondingly arranged at one end of the second light channel 213 away from the groove 2111, and is glued on one side of the first connecting piece 21 in the second direction.

[0047] For the multi-image sensor optical system 100, it is crucial to ensure that the incident light is vertically irradiated on the center of the receiving plane of the image sensor, which is the key to ensuring the image quality. Therefore, during installation, how to adjust the relative position relationship between the mounting plates and the connecting pieces, and how to know that the appropriate position has been adjusted, are difficult problems during installation.

[0048] In order to solve the difficult problems during installation of the multi-image sensor optical system 100, and thus ensure the imaging quality of the multi-image sensor optical system 100, the utility model also provides a fitting device 200, which is shown in Figure 4, for correcting the multi-image sensor optical system 100 when assembled, the fitting device 200 comprises: a fixing member 210, a target assembly 220, a clamping assembly 230, an adjusting assembly 240 and a dispenser (not shown); the fixing member 210 is used to fix the lens barrel 1; the target assembly 220 is arranged at one end of the lens barrel 1 in the first direction, so as to emit image light to the incident end 11; the clamping assembly 230 has two clamping members that can move close to or away from each other; the adjusting assembly 240 has a movable end, which has a movable stroke in at least the first direction, the second direction and the third direction, and is used to mount the clamping assembly 230; the dispenser is arranged on one side of the clamping assembly in the third direction, and is used to dispense glue to fix the first mounting plate and the second mounting plate; wherein the clamping assembly 230 and the adjusting assembly 240 are both provided with two, the two clamping assemblies 230 are respectively mounted on the movable ends of the two adjusting assemblies 240 and are respectively used to clamp the first mounting plate 4 and the second mounting plate 5, and one of the adjusting assemblies 240 is arranged on one side of the connecting assembly 2 away from the target assembly 220 in the first direction, and the other adjusting assembly 240 is arranged on one side of the connecting assembly 2 in the second direction.

[0049] When the fitting device 200 is used, first, the fixing member 210 is used to fix the lens barrel 1, so that the lens barrel 1 extends in the first direction, and the target assembly 220 emits light, so that the light emitted by the target assembly 220 coincides with the optical axis of the lens barrel 1, and at this time, the two clamping assemblies 230 are used to clamp the first mounting plate 4 and the second mounting plate 5 respectively. Taking the adjusting assembly 240 arranged on one side of the connecting assembly 2 in the second direction as an example, the adjusting assembly 240 is referred to as the first adjusting assembly 240a, and the clamping assembly 230 connected with the first adjusting assembly 240a is referred to as the first clamping assembly 230. After the first clamping assembly 230 clamps the second mounting plate 5 (the clamping can be realized by using a sliding table air cylinder, please refer to Figure 6 ), first, the position of the second mounting plate 5 is adjusted in the first direction and the third direction by the first adjusting assembly 240a, so that the reflected light can be shot to the center position of the receiving plane of the second image sensor 7, and then the position of the second mounting plate 5 is adjusted in the second direction, so that the second mounting plate 5 is close to and fits the side of the first connecting member 21 in the second direction, at this time, glue is applied, and glue joint is performed, after the glue is cooled, the two are completely fixed, and then the first clamping assembly 230 is loosened. The selection and fixing of the position of the second image sensor 7 are the same as those of the first image sensor 6, and will not be described here.

[0050] In order to make the light emitted by the target assembly 220 coincide with the optical axis of the lens barrel 1, the target assembly 220 comprises a transmitter 221 for emitting image light and a calibration assembly 222 having a mounting end with at least a movable stroke in the second direction and the third direction, the mounting end being used for mounting the transmitter 221. The position of the transmitter 221 is adjusted using the calibration assembly 222, so that the transmitter 221 corresponds to the lens barrel 1, and the light emitted by the target assembly 220 coincides with the optical axis of the lens barrel 1. The calibration assembly 222 can be in the form of a slide rail sliding in the third direction, and an active rod is arranged to be telescopically arranged in the second direction, one end of the active rod sliding on the slide rail, and the other end of the active rod being fixedly connected with the transmitter 221. The calibration assembly 222 can be in the above form, but is not limited to the above form, and can satisfy the adjustment of the position in the plane perpendicular to the first direction.

[0051] For the adjustment assembly 240, the first direction, the second direction and the third direction are implemented as follows: Figure 5 Taking the first adjustment assembly 240a as an example, the first adjustment assembly 240a comprises a first adjustment module 241, a second adjustment module 242 and a third adjustment module 243. The first adjustment module 241 is arranged on one side of the connecting assembly 2 in the second direction, and comprises a first active part movably arranged in the third direction. The second adjustment module 242 is mounted on the first active part, and comprises a second active part movably arranged in the first direction. The third adjustment module 243 is mounted on the second active part, and comprises a third active part movably arranged in the second direction. In more detail, the first adjustment module 241 comprises a first active part, a first mounting part and a first operating rod. The first active part and the first mounting part slide relative to each other in the third direction. The first mounting part is used for mounting on the base to keep the position fixed. The first mounting part has a threaded hole penetrating in the third direction. The first operating rod is provided with threads on the side surface and cooperates with the threaded hole. The first operating rod is hinged to the first active part. When the first operating rod is rotated, the first operating rod moves linearly relative to the threaded hole, thereby pushing the first active part to move in the first direction. The second adjustment module 242 comprises a second active part, a second mounting part and a second operating rod. The second mounting part is fixedly connected with the first active part. The second adjustment module 242 is arranged in the same way as the first adjustment module 241, and the third adjustment module 243 is also arranged in the same way, which will not be described here.

[0052] The image sensor is used to convert the received light into an image displayed on the display screen, so that the image displayed on the display screen is in a correct state. Still taking the first adjusting assembly 240a as an example, the first adjusting assembly 240a further comprises a fourth adjusting module 244, the fourth adjusting module 244 is installed on the third movable part, the fourth adjusting module 244 comprises a fourth movable part and a fourth mounting part, and the fourth movable part is arranged to rotate relative to the fourth mounting part about a second direction axis. The fourth mounting part is fixedly connected with the third movable part.

[0053] Due to the fact that the plane on which the first mounting part is installed is not completely perpendicular to the second direction, and the installation error and processing error of the first adjusting assembly 240a, the second image sensor 7 is not perpendicular to the second direction, and the reflected light cannot be vertically incident on the center of the receiving plane of the second image sensor 7. Therefore, it is necessary to further adjust the second mounting plate 5 and the pitch angle. Still taking the first adjusting assembly 240a as an example, the first adjusting assembly 240a further comprises a fifth adjusting module 245 and a sixth adjusting module 246, the fifth adjusting module 245 has a fifth movable part and a fifth mounting part, the fifth movable part can rotate relative to the fifth mounting part about a third direction axis, and the fifth mounting part is fixedly installed on the fourth movable part; the sixth adjusting module 246 is arranged in the same manner as the fifth adjusting module 245, and the sixth adjusting module 246 is installed on the fifth movable part, the sixth adjusting module 246 comprises a sixth movable part, and the sixth movable part is arranged to rotate about the first direction axis.

[0054] The second adjusting assembly 240b is arranged in the same manner as the first adjusting assembly 240a, and for the convenience of installation, the second adjusting assembly 240b can be deformed on the basis of the first adjusting assembly 240a, and the same function can be achieved.

[0055] The use steps of the fitting device 200 are as follows: 1. The lens barrel 1 is fixed by the fixing part 210 (at this time, the connecting assembly 2 is fixedly connected, and the dichroic mirror 3 is fixedly installed in the connecting assembly 2); 2. Adjust the calibration assembly 222 so that the light emitted by the emitter 221 coincides with the optical axis of the lens barrel 1; 3.
