The LUNA Spatial Light Modulator is our most compact SLM platform for integration into small sized or even portable solutions.
The LUNA phase only Spatial Light Modulator (SLM) consists of a driver unit with standard digital video interface (DisplayPort) and a phase only LCOS (Liquid Crystal on Silicon) microdisplay with full HD resolution (1920 x 1080 pixel) and 4.5 µm pixel pitch leading to an active area diagonal of 0.39” with an aspect ratio of 16:9.
The driver ASIC is embedded in the LCOS microdisplay itself. This saves board space which enables a very compact driver and makes integration more convenient. The standard driver box has a size of only 84.4 x 47 x 28.8 mm. The display can even accept video data input via a 4-lane MIPI DSI. This brings phase only Spatial Light Modulator technology to a new level of potential for industrial implementations.
The LUNA SLM usees fast full digital addressing which assures high reliability and a compact driver unit. A certain gray level represents a defined average voltage across the LC cell. This voltage leads to a variable tilt of the LC molecules due to their electrical anisotropy. As LC molecules also show optical anisotropy this tilt changes the refractive index of the LC molecules (for incident polarization along the long display axis) which causes a modified optical path length within the LC cell. The addressed gray level is converted into a phase level.
The LUNA driver unit is equipped with an USB interface for changing the voltage vs. phase level distribution (gamma control) and dynamic range (voltage across the LC cell) in order to calibrate the SLM for different wavelengths.
The LUNA SLM is a plug & play phase modulator and can be addressed with phase functions via standard graphics cards as extended monitor device. Addressing can be done using the supplied Pattern Generator software, the HOLOEYE Slideshow Player software or standard image viewer software. HOLOEYE also provides an SLM Display Software Development Kit (SDK) which provides APIs (Application Programming Interface) for different programming languages.
LUNA Phase Only Spatial Light Modulator Versions
HOLOEYE offers different phase display versions which can be driven with the LUNA driver unit. The different display versions are optimized for the use at different wavelength ranges. Currently we offer a VIS version (420 – 650 nm) and a version for the telecommunication waveband around 1550 nm (1400-1700 nm).

LUNA Phase Modulator – Software Features:
The LUNA phase only spatial light modulator devices can simply be addressed like an external monitor using the standard DisplayPort interface of the graphics card. No additional software or dedicated hardware is needed to operate the SLM.
The device is delivered with a Configuration Manager software. The Configuration Manager can be used to change geometrical settings, brightness, contrast and the electrooptical response by applying a new gamma curve or another digital drive scheme. For these advanced calibrations the device uses an USB connection to a virtual COM port of the computer.
In addition a HOLOEYE SLM Pattern Generator software is provided with the SLM:
Computation of computer generated holograms (CGH) from user defined images
generation of SLM signals representing basic optical functions such as lenses, gratings, axicon and vortex functions
superposition of CGH’s with basic optical functions to combine functionalities
Besides that a special SLM Slideshow Player Software comes with the device. Also an SLM Display SDK is available for download which provides APIs (Application Programming Interface) for different programming languages to show images and data/ phase arrays directly on a HOLOEYE Spatial Light Modulator:
