The GAEA-2.1 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 a 10 megapixel (4K) resolution of (max 4160 x 2464 pixel), and 3.74 µm pixel pitch leading to an active area diagonal of 0.7”.  

The GAEA-2.1 SLM is a plug & play phase modulator device and can be addressed with phase functions via standard graphics cards as an extended monitor device. 8 bit gray level patterns (= 8 bit phase levels) can be addressed. The used graphics card must support HDMI-2 and 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. HOLOEYE also provides an SLM Display Software Development Kit (SDK) which provides APIs (Application Programming Interface) for different programming languages.

The very small pixel size of the GAEA-2.1 SLM display enables high diffraction angles of up to 12°.

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), a version optimized for high speeds which can be used in RGB color field sequential (CFS) phase applications, a NIR version (650 – 1100 nm) and a version for the telecommunication waveband around 1550 nm..

Color Field Sequential (CFS) Operation

The updated firmware of the GAEA-2.1 Spatial Light Modulator enables the use in Color Field Sequential (CFS) phase modulation mode. The driver enables addressing of 3 x 8 bit within a frame (180 Hz). The SLMs also feature an RGB light source sync connector for use with RGB color-switchable laser sources.

The GAEA-2.1-CFS-159 is optimized for fast response times for computer generated color holography.
