Optical Coherence Tomography using a wavelength swept laser

Optical Coherence Tomography using a wavelength swept laser

The light source is a wavelength swept laser from Micron Optics operating in the 1310nm wavelength range. The laser light is invisible, and can only be viewed with an IR Card. The wavelength sweep is not linear in time

a) Does the axial Point Spread Function (PSF) change as a function of distance? Why?

b) Does the height of the Point Spread Function (PSF) change as a function of distance? Why?

c) What are the effects of sampling the signal uniformly in time versus uniformly in wavenumber?

d) Is there a difference between positive and negative values of the optical path length difference? Why?
