AOTF AOM PCAOM Controller for Under $100!
In this episode I take a look at an Acousto-optic Tunable Filter!
This device allows us to modulate or pick a wavelength from a multiline Laser using very high frequency sound waves, that are coupled into a crystal using a Piezoelecric transducer.
Since this did not come with a controller, I show you how to build a controller for these devices for under 100 bucks, using an inexpensive Voltage controlled Oscillator (VCO) and an RF Amplifier!
