Does CCD resolution have nothing to do with pixel size?

Yesterday afternoon, I mentioned that "there must be a relationship between pixel resolution and pixel size. The smaller the pixel size, the higher the resolution." My colleagues and I argued that my concept is problematic, the two are two different concepts.

Today, I calmed down and carefully analyzed whether there was any connection between them. Finally, I found this rule.

An object is projected on the CCD target. If the number of pixels covered by the projection is less than three, the nyqust sampling law applies (in fact, the image is not suitable for 3D sampling ?), This object is unlikely to be clearly reproduced. According to this idea, the pixel size can play a huge role. For example, as mentioned above, the pixel size is reduced, and the projection above can cover more pixels. If more than three pixels are involved, the object can be acquired and reproduced clearly. This is equivalent to improving the minimum resolution.

At the same time, if the number of camera pixels is certain, the smaller the pixel size, the camera can be closer to the surface of the object to be taken, which is beneficial to the reduction of the entire system structure.

Haha, the above phenomenon is actually obvious. No turning
