Is Nyquist Theorem Applicable to a Detector with 500 Pixels and 5um Pixel Size?

[Grufey]

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

f_s = f_s/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.
