Description

Technical Field

[0001] The utility model relates to the technical field of structured light imaging, in particular to an optical path device and a multi-channel lossless switching parallel optical path system using the optical path device. Background Art

[0002] In a microscope system, it is sometimes necessary to set up optical paths for multiple channels. The situations in which multiple channels need to be set up mainly include the following:

[0003] Multicolor microscopy: When different elements or components in a sample need to be observed simultaneously, such as using multiple fluorescent dyes to label different cellular structures or molecules, each fluorescent dye may require a separate channel for detection and imaging. This allows for simultaneous acquisition of multiple information, adding more context to the observation and providing a more comprehensive experimental result.

[0004] Avoid fluorescence crosstalk: When performing multicolor experiments using fluorescence microscopy, different fluorophores may produce crosstalk due to overlapping emission spectra. To avoid this, multiple channels need to be used with appropriate filter plates to ensure that the emission intensity captured from each fluorophore is maximized while minimizing crosstalk between detection channels.

[0005] Improve imaging speed and accuracy: In some experiments, it is necessary to quickly capture multiple fluorescence signals to study the dynamic changes of biological processes. By adding multiple channels, different fluorescence signals can be collected simultaneously, thereby improving imaging speed and experimental efficiency.

[0006] Studying complex biological processes: Research in fields such as neuroscience and immuno-oncology often requires observing the interrelationships and spatial distributions of multiple proteins, cell types, or biomarkers. Multiple channels can help researchers gain a more comprehensive understanding of these complex biological processes.

[0007] In the prior art, multiple channels are generally set up inside the microscope system and switched as needed, such as Figure 1 and Figure 2 This is an optical dual-channel module of the prior art. Channel switching is performed by changing the light-transmitting and light-blocking states of the metal blade wheel (the area where the blades are rotated is the light-blocking area, and the area where the gaps between the blades are rotated is the light-transmitting area). Figure 1 The optical path of channel a (dashed line): Imported module 11 Reflection state of the dichroic prism 231 Reflector 221 Light-transmitting area of ​​the metal blade wheel 21 Second target device 32 Reflector 222 Reflection state of the beam splitter prism 232 Export module 12, Figure 2 Optical path of channel b (solid line): Imported module 11 Transmission state of the dichroic prism 231 Light-transmitting area of ​​the metal blade wheel 21 à first target device 31 Transmission state of the beam splitter prism 232 In the outlet module 12, the optical path of channel a is long and that of channel b is short. The two paths of light are switched on and off by a metal blade wheel driven by a running motor. However, after the light of channel a is split twice, the remaining light is only 1 / 4 of the original light, resulting in a significant loss of light efficiency. Therefore, there is an urgent need to solve the problem of light efficiency loss. Summary of the Invention

[0049] In order to make the purpose, technical solutions and advantages of this utility model more clear, the following Figure 3-10 And embodiments, the utility model is further described in detail. Example

[0050] An optical path device of this embodiment, such as Figure 3 and Figure 4 As shown, it includes a circular light plate and a motor for driving the light plate to rotate, and a light-transmitting area and a light-reflecting area are provided on the light plate, and the area ratio of the light-transmitting area and the light-reflecting area is 1:1.

[0051] By using the optical path device of this embodiment, the motor is controlled to drive the light plate to switch between the light-transmitting area and the light-reflecting area, so that the two optical paths can be quickly switched without loss. The two optical paths have the same optical path, and the two optical paths can be completely equivalent. Example

[0052] An optical path device 1 of this embodiment includes six reflectors, two target devices and two optical path devices of embodiment 1.

[0053] The two optical path devices are a first optical path device 21 and a second optical path device 22. The center points of the first optical path device 21 and the second optical path device 22 lie on the same straight line, and the straight line is parallel to the incident light. The angle between the first optical path device 21 and the incident light is 45 degrees, and the angle between the second optical path device 22 and the incident light is 135 degrees. The reflection crossover of light at 45 degrees improves symmetry.

[0054] The first reflector 211 is located directly below the first optical path device 21 and is parallel to the first optical path device 21. The second reflector 212 is located directly below the second optical path device 22 and is parallel to the second optical path device 22. The third reflector 221 is located between the first light plate 201 and the second light plate 202 and is parallel to the second light plate 202. The fourth reflector 222 is located directly above the third reflector 221 and is parallel to the third reflector 221. The first target device 31 is placed between the fifth reflector 223 and the fourth reflector 222, and the fifth reflector 223 and the fourth reflector 222 are symmetrically arranged relative to the first target device 31. The sixth reflector 224 is located between the third reflector 221 and the second light plate 202, and the sixth reflector 224 is parallel to the first light plate 201. The second target device is located between the first reflector 211 and the second reflector 212.

[0055] Using the optical path device 1 of this embodiment, when it is necessary to compare different devices, superimpose images, etc., for example: to check whether they are qualified products, the first target device 31 is a relatively complex device gold sample 31, and the second target device is a comparison device 32. When the optical path channel is switched, if the two achieved effects are consistent, it means that they are qualified, otherwise they are unqualified.

[0056] This embodiment uses a motor to drive the light plate to be located in the light-transmitting area or the light-reflecting area, which can quickly achieve lossless switching of the light path. Different light paths have the same optical path, and different light paths can be completely equivalent.

[0057] Of course, the first target device 31 and the second target device can also be different gratings, flat optical devices of different thicknesses, or different lenses, etc. Different target devices can be placed according to different requirements. Example

[0058] A dual-channel lossless switching parallel optical path system of this embodiment, such as Figure 5 and Figure 6 As shown, it includes an inlet module 11, an optical path device 1 of embodiment 2, and an outlet docking module 12 connected in sequence.

[0059] Utilizing a multi-channel lossless switching parallel optical path system of this embodiment, when light exits the inlet module 11, it enters the optical path device 1 and finally enters the outlet docking module 12. When it is necessary to compare different devices, overlay images, etc., the power components of the optical path devices in the optical path device 1 drive the light plate to be located in the light-transmitting area or in the light-reflecting area, which can quickly realize lossless switching of the optical path. Different optical paths have the same optical path, which can achieve complete equivalence of different optical paths.

[0060] in, Figure 4 is a schematic diagram of channel a, Figure 5 Schematic diagram of channel b:

[0061] Figure 5 The optical path is: Imported module 11 The light-transmitting area of ​​the first optical plate of the first optical path device 21 The third reflecting mirror 221 Fourth reflecting mirror 222 Second target device Fifth reflecting mirror 223 Sixth reflecting mirror 224 The light-transmitting area of ​​the second optical plate of the second optical path device 22 Export docking module 12.

[0063] Because both channel a and channel b are realized by combined area switching of the motion motors 21 and 22 , light enters the outlet docking module 12 with almost no loss.

[0064] As a preferred embodiment, the two optical path devices use a linkage circuit to achieve being located in the light transmission area or the light reflection area at the same time. The linkage circuit can simultaneously control the switching of the two optical path devices, which is more efficient. Example

[0065] An optical path device of this embodiment, such as Figure 7 As shown, it includes a circular light plate and a motor for driving the light plate to rotate, and a light-transmitting area and a light-reflecting area are provided on the light plate, and the area ratio of the light-transmitting area and the light-reflecting area is 2:1.

[0066] By using the optical path device of this embodiment, the motor is controlled to drive the light plate to switch between the light-transmitting area and the light-reflecting area, so that the three optical paths can be quickly switched without loss. Moreover, the three optical paths have the same optical path, and the three optical paths can be completely equivalent. Example

[0067] An optical path device 1 of this embodiment includes nine reflectors, three target devices and four optical path devices of embodiment 4.

[0068] The four optical path devices are respectively the first optical path device 21, the second optical path device 22, the third optical path device 23 and the fourth optical path device 24, the nine reflectors are respectively the first reflector 211, the second reflector 212, the third reflector 221, the fourth reflector 222, the fifth reflector 223, the sixth reflector 224, the seventh reflector 225, the eighth reflector 226 and the ninth reflector 227, and the three target devices are respectively the first target device 31, the second target device 32 and the third target device 33.

[0069] With the optical path device 1 of this embodiment, the first target device 31 , the second target device 32 and the third target device 33 are different grating images respectively. Through multiple grating images, a better image can be obtained through an algorithm.

[0070] This embodiment uses a motor to drive the light plate to be located in the light-transmitting area or the light-reflecting area, which can quickly achieve lossless switching of the light path. Different light paths have the same optical path, and different light paths can be completely equivalent. Example

[0071] A three-channel lossless switching parallel optical path system of this embodiment, such as Figures 8 to 10 As shown, it includes an inlet module 11, an optical path device 1 of Example 5, and an outlet docking module 12 connected in sequence.

[0072] Utilizing a multi-channel lossless switching parallel optical path system of this embodiment, when light exits the inlet module 11, it enters the optical path device 1 and finally enters the outlet docking module 12. When comparison of different devices, image superposition, etc. is required, the power component (motor) of the optical path device in the optical path device 1 drives the light plate to be located in the light-transmitting area or in the light-reflecting area, which can quickly achieve lossless switching of the optical path. Different optical paths have the same optical path, and different optical paths can be completely equivalent.
