   SLMs are used extensively in holographic data storage setups to encode information into a laser beam similarly to the way a transparency does for an overhead projector. They can also be used as part of a holographic display technology. In the 1980s, large SLMs were placed on overhead projectors to project computer monitor contents to the screen.

7. Laser projector - Wikipedia

   en.wikipedia.org/wiki/Laser_projector

   In the case of using a computer to control a laser projector, a digital-to-analog converter (DAC) is needed to convert the digital control signal from the computer into analog signals that control the scanners in the laser projector. Typically, two channels are used for x-y position control and three channels are used for controlling the RGB ...
