Patent ID: 8804133

Claim:
A method of adjusting imaging at least a part of an object, comprising: splitting electro-magnetic radiation to first and second portions; propagating said first portion toward said part and said second portion toward a reference element; spectrally diffracting said first portion using a spectral diffraction imaging element; spectrally dispersing at least one of said first portion and said second portion using a spectral dispersion element; combining between reflections of said spectrally diffracted first portion and said second portion to produce an interference signal; capturing an image of the part from said interference signal; and presenting said image to a user; receiving from a user instructions to optimize the quality of said image; using said spectral dispersion element to perform: an adjustment of a second order dispersion of at least one of said first portion and said second portion to change a tilt of an image plane in the field of view of said part, or an adjustment of a third order dispersion of at least one of said first portion and said second portion to change a curvature of said image by changing, according to said user instructions; wherein said adjustment is made by changing a deviation between the phase of at least one spectral component of said first portion and the phase of at least one spectral component of said second portion.
