Problem

A coherent imaging system uses a lens of numerical aperture NA=0.85\mathrm{NA} = 0.85 on the object side, illuminated at λ=486 nm\lambda = 486\ \mathrm{nm} (vacuum wavelength). (a) State the coherent transfer function of the system in words, and give the value of the coherent cutoff frequency νc,coh\nu_{c,\mathrm{coh}} at the object, in cycles per millimetre.
