RFJAS Animation: High-Precision Optical Alignment
This animation illustrates the working principle of the Radio Frequency Jitter Alignment Sensing (RFJAS) scheme.
The primary component of this setup is an electro-optic beam deflector, which scatters a laser's carrier beam into higher-order
Hermite-Gauss modes.
The animation demonstrates how this technique is used for high-precision optical alignment. The setup includes a
laser source, a beam deflector, an optical cavity, and a demodulation photodiode.
