GAEA-2 10 Megapixel Phase Only LCOS-SLM (Reflective)

The GAEA-2 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 (max 4160 x 2464 pixel) and 3.74 µm pixel pitch leading to an active area diagonal of 0.7”.

The GAEA-2 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.
