描述
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. The 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), a NIR version (680 – 110 nm) and a version for the telecommunication waveband around 1550 nm (1400-1700 nm).
| Version | Wavelength Range | Reflectivity | Max. Phase Shift |
| LUNA-VIS-111 | 420 – 650 nm | 61 – 67 % (average 64 %) | 4.3 π @ 450 nm 3.2 π @ 520 nm 2.4 π @ 635 nm |
| LUNA-NIR-147 | 680 – 1100 nm | 60 – 75 % (average 65 %) | 3.3 π @ 800 nm 2.3 π @ 1064 nm |
| LUNA-TELCO-115 | 1400 – 1700 nm | 70 % | 2.3 π @ 1550 nm |
Color Sequential Phase Operation
The LUNA-VIS-111 is also capable to be used in color field sequential (CFS) phase applications with >= 32 linearly distributed phase values for each color (R, G, B) from 0 π to 2.2 π. The light source is triggered for ~1.1 ms per color field.
A basic requirement to achieve the faster response time necessary for CFS, is a higher display temperature of 55°C and adapted voltage settings, saved in the corresponding configuration file. We highly recommend to use a HOLOEYE Thermal Management System (TMS) in order to control the display temperature in CFS mode.

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:
- C or C++ compiler (e. g. Microsoft Visual C++ Compiler)
- National Instruments LabVIEW 2011 and later
- MathWorks MATLAB R2009b and later
- Octave 7.2
- Python 2.7 and 3.x
