Exploring the HF2LI-MOD: Measuring Bessel Functions

on 20.10.2011 at 12:40 by Andrin
In this post, I demonstrate the capabilities of the HF2LI-MOD upgrade by demodulating 4 FM sidebands simultaneously. With the help of a basic sweep routine programmed in LabVIEW, I measure 5 Bessel functions by direct sideband demodulation of an FM signal. This post might give you an inspiration on how to improve your measurement sensitivity by introducing an advanced demodulation scheme of multiple sidebands.

Pseudoheterodyne Detection in Optics

There is a new application note about pseudoheterodyne detection in nearfield optics. The application has also relevance for laser spectroscopy. Hereafter are a few personal comments about phase sensitive detection in optics, as I participated in the described experiments.
