A fine square wire mesh with 50 wires per cm is placed vertically in the object plane of the optical computer of Fig. 13.50. If the lenses each have 1.00-m focal lengths, what must be the illuminating wavelength, if the diffraction spots on the transform plane are to have a horizontal and vertical separation of 2.0 mm? What will be the mesh spacing as it appears on the image plane?
