Paper Abstract

The critical aspects of signal sampling in the context of optical measurements are reviewed. A parallel is drawn between optical- and time-signal sampling, which shed light on the impact and interplay between key parameters. All key parameters have their mirror image in both pictures, time ? frequency or optical-frequency ? optical-delay. The equivalence is made specific, between optical sampling-step, resolution bandwidth, interferograms, photodetector bandwidth or laser lineshape on one hand, and sampling rate, low-pass filter, signal spectrum and signal bandwidth on the other hand, along with the conditions they should fulfill, in both pictures, given an actual setup.
