A '''spatial light modulator''' is a gadget that can vary the properties of [[light]] that goes through it or reflects off of it. It can modulate the intensity and/or phase of light across a two-dimensional physical array. It can be used for [[computer-generated holography]].<br />
<br />
Technologies for spatial light modulators include [[DMD]] and [[LCOS]].<br />
<br />
Companies that make spatial light modulators include [[Texas Instruments]], [[HoloEye]], and [[Meadowlark optics]].<ref name="c127">{{cite web | title=1024 x 1024 Spatial Light Modulator | website=Meadowlark Optics | date=2024-11-20 | url=https://www.meadowlark.com/shop/slms/1024-x-1024-spatial-light-modulator/ | access-date=2024-12-14}}</ref><br />
<br />
Spatial light modulators are related to [[microdisplay]]s.<br />
<br />
SLMs can either be amplitude modulation SLMs or phase modulation SLMs, typically.<br />
<br />
LCOS SLMs can theoretically modulate amplitude, polarization, and phase all at once.<ref name="w206">{{cite web | title=LCOS Microdisplays | website=Home - HOLOEYE Systems, Inc. | date=2020-11-09 | url=http://holoeyesystems.com/lcos-microdisplays/ | access-date=2024-10-15}}</ref><br />
<br />
==Modulation==<br />
'''Amplitude modulation''' is a kind of modulation of [[light]].<br />
<br />
It is used by some kinds of SLMs, for example [[DMD]]s.<br />
