GAEA 10 Megapixel Phase Only Spatial Light Modulator (Reflective)

The GAEA phase only Spatial Light Modulator (SLM) consists of a driver unit with standard digital video interface (HDMI) and a phase only LCOS (Liquid Crystal on Silicon) microdisplay with 10 megapixel (4K) resolution (4094 x 2464 pixel) and 3.74 µm pixel pitch leading to an active area diagonal of 0.7”.

The GAEA SLM is a plug & play phase modulator device and can be addressed with phase functions via standard graphics cards as extended monitor device. 8 bit gray level patterns (= 8 bit phase levels) can be addressed. The used graphics card must be able to provide an uncompressed output of at least 3840 x 2160 pixel resolution. Addressing can easily be done using the supplied Pattern Generator software or the SLM Slideshow Player software or standard image viewer software.

The very small pixel size of the GAEA SLM display enables high diffraction angles

GAEA 10 Megapixel Phase Modulator Versions

HOLOEYE offers different versions of the GAEA phase only spatial light modulator. The different

panel versions are optimized for the use at different wavelength ranges. Currently we offer a VIS

version (420 – 650 nm) and a version for the telecomminication waveband around 1550 nm.

A version for the NIR wavelength (650 – 1100 nm) will be released by second half of 2016.

PLUTO SLM Calibration Software

The GAEA 4K phase only modulator devices can simply be addressed like an external monitor using

the standard HDMI interface of the graphics card. No additional software or dedicated hardware is

needed to operate the SLM.

The device is delivered with a GUI (Graphical User Interface) based Configuration Manger 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.

An USB interface is used for these advanced callibrations. In addition a HOLOEYE

SLM Pattern Generator software is provided with the SLM. Key features of which are:

 

● 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, for LabView users a Labview SubVi for addressing of optical functions is included.

● SLM Configuration Manager: Brightness / Contrast / Geometry / Gamma Control

● SLM Pattern Generator: Basic DOE computations; Generation of optical functions (Circular

Aperture, Fresnel Zone Lens, Axicon, Single and Double Slit …); Gratings (incl. Blazed and

Sinusoidal), superposition of functions (e.g. prisms, Zernike polynomials…)

● SLM Slideshow Player: Plays slideshow of user defined precalculated functions or images
