The SLM acts as a second monitor, but the SLM itself only changes the phase of the reflected light. To change the amplitude (and see something), a pair of polarizers is necessary.

Spatial light modulators (SLMs) are active optical components that can alter a light beam''s amplitude, phase, or polarization. For this tech-talk, I''ll focus on a specific subset: those that achieve this using a

The spatial light modulator can be thought of digitally recreating the desired wavefront to couple the light to a given fiber or location based on the wavefront of the incident beam of light.

By using a combination of the FLC crystal, suitable polarizing optics and by switching the polarity of the applied voltage, it is possible to transmit or absorb an input light beam. The FLC device can be used

Correction is accomplished by using two spatial light modulators in series. The first performs the necessary amplitude modulation, also introducing a phase change. The second SLM restores the
