Recovering distance information in spectral domain interferometry

HIGHLIGHTS

• who: Adrian Bradu from the Experimental set-upA schematic diagram of the UHR spectrometer based SDI instrument used for our experiments is depicted in Fig., . Light from a supercontinuum broadband light source (SuperK Extreme, NKT Photonics, repetition rate , MHz), is directed towards the sample (S) and the reference (R) arms of an interferometer by a, directional coupler DC. In the sample arm, S, light is conveyed towards the sample via an achromatic lens LS, and an achromatic telecentric scan lens SL. When the instrument was used for imaging purposes, a galvanometer mirror was placed between LS and . . .
