The visible light channel can show the real-time dynamics of the target and has the same function as a camera; the infrared light channel can show the on-site temperature difference in the form of a thermal image. There are two solutions for dual-light fusion. One is a purely optical solution, in which the light is split into two sensors through a prism and then fused. This solution has higher requirements for accuracy and higher cost. Another solution is to quickly switch the filter between two frame exposures of a sensor, and then fuse the two frames of images. This solution places high requirements on the speed of filter switching.

Referring to FIGS. 3 and 4 , the filter 27 includes a first filter 28 and a second filter 29 . The first filter 28 and the second filter 29 are fixed to the filter holder 22 . When the filter holder 22 is in the first position, the first filter 28 faces the sensor 21 , and when the filter holder 22 is in the second position, the second filter 29 faces the sensor 21 . By quickly switching the first filter 28 and the second filter 29 between two frames of exposure of the sensor 21, and then fusing the two frames of images, the purpose of dual-light fusion is achieved. The filter holder 22 rotates to change the positions of the first filter 28 and the second filter 29 relative to the sensor 21 . When the first optical filter 28 rotates to face the sensor 21, the sensor 21 senses the light passing through the first optical filter 28 and generates a first frame image.

The end 47 extends around the buffer block 34 toward the outside of the buffer block 34 , and the second end 48 is located outside the buffer block 34 and extends to the rotation path of the filter holder 22 for collision with the filter holder 22 . The rotating filter holder 22 collides with the second end 48 of the buffer elastic member 37, causing the buffer elastic member 37 to elastically deform. The filter holder 22 transfers energy to the buffer block 34 to achieve deceleration of the filter holder 22. At the same time, since the buffer elastic member 37 has elasticity, it can avoid damage caused by rigid collision between the buffer block 34 and the blocking member 33 . In some embodiments, the buffer elastic member 37 is a torsion spring. The buffer elastic member 37 is received between the buffer block 34 and the base 11 .

The other end of the member 38 is located outside the buffer block 34 and abuts with the base 11 . After the buffer block 34 hits the blocking member 33 , the reset elastic member 38 causes the buffer block 34 to move in a direction away from the blocking member 33 and reset. Since the switching speed of the filter holder 22 is fast, setting the reset elastic member 38 can quickly return the buffer block 34 and the buffer elastic member 37 to the initial position, preparing for the next collision of the filter holder 22 with the buffer elastic member 37.

The buffering assembly 30 extends between the blocking member 33 and the limiting member 39 . During this time, it can move between the blocking member 33 and the limiting member 39 . When the filter holder 22 is in the first position or the second position, the buffer block 34 is separated from the blocking member 33 and stops against the limiting member 39 . After the buffer block 34 hits the blocking member 33 , the reset elastic member 38 drives the buffer block 34 to move in a direction away from the blocking member 33 and reset until the buffer block 34 is blocked by the limiting member 39 . The blocking member 33 and the limiting member 39 jointly limit the displacement of the buffer block 34, and the buffer block 34 moves between the blocking member 33 and the limiting member 39. The limiting member 39 and the blocking member 33 may be distributed on a circumference, and the buffer block 34 rotates between them. The limiting member 39 can ensure that each time the filter holder 22 switches between the first position and the second position, the starting position of the buffer block 34 is the same and the compression amount of the buffer elastic member 37 is the same, thereby ensuring that the movement of the filter holder 22 is smooth.

The light sheet support 22 collides, driving the buffer block 34 to move until it hits the blocking member 33 . After the buffer block 34 hits the blocking member 33 , the reset elastic member 38 causes the buffering block 34 to move in a direction away from the blocking member 33 of the first buffer assembly 31 and reset. , and finally stops at the limiter 39.
