Resolution, Scanning Speed and Demodulation Bandwidth

on 06.12.2011 at 09:40 by Andrin on Blog of Andrin Doll
This post is about the interplay between resolution, scanning speed and demodulation bandwidth. I demonstrate how the scanning process can be described in spatial, time and frequency domain, and show that this is a valuable toolbox to analyze your measurement setup as a whole.

Pseudoheterodyne Detection in Optics
