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-VIS-111 version is capable of use 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.
