SUMMARY

The discussion centers on the applicability of the Nyquist Theorem to a detector with 500 pixels and a pixel size of 5 µm. The participants clarify that the sampling rate is determined to be 1 / (5 µm), leading to a spatial sampling of 0.01 µm per pixel. Once the pixel size is accurately accounted for, the application of the Nyquist Theorem becomes straightforward, confirming that the theorem is indeed applicable in this scenario.

Homework Statement


Given a detector with 500 pixels, and a pixel size of 5 um, is it posible to register next signal?

I = cos(2 π 4 x)

were x is expressen in um

Homework Equations



fs = fs/2

The Attempt at a Solution



My problem is with the pixel size, I mean, the sampling rate will be 5/500=0.01 um/px, or it should be 1/5 um-1.

Once this drawback is solved, the solution is trivial, the Nyquist theorem is applied.

Thanks in advance

There is one pixel every 5µm, so the sampling rate is 1 / (5µm). If the chip size were 5µm, then you would have 0.01 µm/pixel.
