Observation of tracking camera cross-section by mechanical grinding.
I would like to introduce "Cross-sectional observation of tracking camera using mechanical polishing." Regarding the structure of the tracking camera components, when viewed from above, the lens can be identified. Although it cannot be clearly seen in the X-ray image, the lens is incorporated into the convex part. Additionally, the cross-sectional structure is similar to that of an RGB sensor, featuring a back-illuminated CMOS structure. However, since color information is not necessary for the tracking camera, there is no color filter layer. A jagged uneven shape was observed on the surface of the photodiode.
