The GAEA-C 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 4094 x 2400 pixel resolution and 3.74 µm pixel pitch leading to an active area diagonal of 0.7”. The GAEA-C 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. Addressing can be done using the supplied Pattern Generator software, the SLM Slideshow Player software or standard image viewer software. HOLOEYE also provides an SLM Display Software Development Kit (SDK) which provides APIs for different programming languages. The very small pixel size of the GAEA-C SLM display enables high diffraction angles.
LUNA Phase Only Spatial Light Modulator The LUNA Phase Only Spatial Light Modulator is our most compact SLM platform for integration into small sized or even portable solutions.
The LETO-3 phase only Spatial Light Modulator is based on a reflective LCOS microdisplay with full HD (1920 x 1080 pixel ) resolution. With a pixel pitch of 6.4 µm and a small interpixel gap of 0.2 µm the LETO-3 SLM provides a high fill factor of 93%. The LETO-3 Spatial Light Modulator offers a reflectivity between 62% up to 75% (dependent on wavelength and version). The device offers diffraction efficiencies of more than 80% (16 level blazed grating) which leads to a total light efficiency of ~ 60%. The LETO-3 SLM driver is prepared to work in color-field-sequential (CFS) mode e.g. with color-switchable LASER or LED lighting and the device features an LED-connector which can be used to synchronize the light source with the device. The driver features 4 slots with preconfigured CFS configurations for different environments which can be slected using the Configuration Manager Software.
