Spatial Light Modulator (SLM) -Technology
|
|
HOLOEYE´s Spatial Light Modulator (SLM) systems are based on translucent or reflective liquid crystal microdisplays. These devices can modulate light spatially in amplitude and phase, so they act as a dynamic optical element. The optical function or information to be displayed can be taken directly from the optic design software or an image source and can be transferred by a computer interface.
|
Implementation is accomplished using the VGA or DVI port of a standard PC graphics card. The Spatial Light Modulator can be used just like an external plug & play monitor. In many cases no additional optics are necessary. The Spatial Light Modulator can be incorporated in existing optical setups and devices. To guarantee the best performance, optical characterization measurements (e.g. phase modulation) are performed by HOLOEYE for each individual device.
 Spatial Light Modulators Overview & Comparison - Data Sheet
HOLOEYE offers a great variety of Spatial Light Modulators:
|
HOLOEYE´s spatial light modulators are suitable for a wide range of photonic applications. These systems are suitable for almost any optical system, starting from imaging applications using white light and coherent light sources up to the utilisation as an addressable optical element.
The highest potential of Spatial Light Modulators is the use as a dynamic phase modulating device, which acts as an addressable diffractive element. Application fields range from bio-photonics, optical metrology, holography, optical interconnection such as switching and information encoding, interferometry to material processing.

Spatial Light Modulator Driver Software and Application Software:
|
|
All HOLOEYE Spatial Light Modulators are controlled by a HOLOEYE driver software which runs on all Windows platforms. This software gives the opportunity to control all relevant image parameters and provides a very easy gamma control to configure the Spatial Light Modulator for different applications and wavelengths.
Furthermore, a tailored Spatial Light Modulator application software allows the simple generation of diverse dynamic optical functions like gratings, lenses, axicons and apertures as well as the calculation of diffractive optical elements (DOE) from user defined images.
