OverviewBeam stabilizationHistoryTip–tilt correctionIn astronomyIn retinal imagingIn microscopyOther uses
A rather simple example is the stabilization of the position and direction of laser beam between modules in a large free space optical communication system. Fourier optics is used to control both direction and position. The actual beam is measured by photo diodes. This signal is fed into analog-to-digital converters and then a microcontroller which runs a PID controller algorithm. The controller then drives digital-to-analog converters which drive stepper motors attached to mirror mounts.
Adaptive Optics – systems, wavefront correction, real-time optical
Adaptive optics technology is available commercially in various forms. For research and custom optical setups, individual components — such as deformable mirrors and wavefront sensors — are often
