Optical coherence tomography, Physics

Assignment Help:

Assume we place a screen with two parallel slits right in front of a lens (with focal distance f ), and illuminate with light (at wavelength λ) from far away. (a) What will be the distance between the adjacent peaks (valleys) of the interference fringes along the focal plane? (b) What will happen if we increase the distance d between two slits?

Two OCT systems, A is using a SLD source centered at 790 nm with a bandwidth of 75 nm, and B is using a Cr:Forstrite laser centered at 1260 nm with  a bandwidth of 120 nm. 1) If I want to visualize sharp structures, which system should I use? 2) If I want to visualize deep structures, which system should I use?
