beam of light. A simple example is an Overhead proiector transparency. Usually when the phrase SLM is

used, it means thai the transparency can be controlled by a Computer. In the 1980s large SLMs were placed

on overhead projectors to project computer monitor contents to the screen. Since then more modern

Projectors have been developed where the SLM is built inside the projector. These are commonly used in

meetings of all kinds for presentations. Usually, an SLM modulates the Intensity ofthe light beam, however it

is also possible to produce devices that modulate the phase ofthe beam or both the intensity and the phase

simultaneously. SLMs are used extensively in holographic data storage setups to encode information into a

laser beam in exactly the same way as a transparency does for an overhead projector. They can also be used

as part of a holographic display technology. SLMs have been used as a component in optical computing.

==Electrically-addressed Spatial Light Modulator (EASLM)== As its name implies, the image on an

electrically-addressed spatial light modulator is created and changed electronically, as in most electronic

displays. EASLMs usually receive input via a conventional interface such as VGA input. They are commonly

available at resolutions up to SXGA (1280 * 1024). Unlike ordinary displays, they are usually much smaller

(having an active area of about 2 cm2) as they are not normally meant to be viewed directly. An example of

an EASLM is the Digital Micromirror Device at the heart of DLP displays. ==Optically-addressed Spatial

Light Modulator (OASLM)== The image on an optically-addressed spatial light modulator, also known as a

light valve, is created and changed by shining light encoded with an image on its front or back surface. A

photosensor allows the OASLM to sense the brightness of each pixel and replicate the image using liquid

crystals. As long as the OASLM is powered, the image is retained even after the light is extinguished. An

electrical signal is used to clear the whole OASLM at once. They are often used as the second stage of a veryhigh-resoiution display, such as one for a computer-generated holographic display. In a process called active

tiling, images displayed on an EASLM are sequentially transferred to different parts an OASLM, before the

whole image on the OASLM is presented to the viewer. As EASLMs can run as fast as 2500 frames per

second, it is possible to tile around 100 copies of the image on the EASLM onto an OASLM while still

displaying full-motion video on the OASLM. This potentially gives images with resolutions of above 100

megapixels. ==Application as ultrafast pulse shapers== Inside a Monochromator in a 4fsetup. Competing
