FIGURE 5.2-2 (A) Spectrum of a spatially sampled, one-dimensional intensity distribution, g(x). g(x) is bandwidth limited so no spectral energy exists for |u| > rc/y r/mm. (X is the angular separation between ommatidial axes.) G(ju) is the baseband spectum; G*(ju) is the (repeated) sampled spectrum. Note that there is no overlap of adjacent G*(ju) elements. (B) Aliased spectrum of an object whose baseband spectrum has energy at frequencies exceeding n/X r/mm. Note that the adjacent spectra of G*(ju) overlap and add together, creating a region of high frequencies above which G(ju) is not recoverable by an ideal low-pass filter with passband between ±n/X r/mm acting on G*(ju).
