The PLUTO phase only Spatial Light Modulator (SLM) consists of a driver unit with standard digital video interface (DVI or HDMI) and a phase only LCOS (Liquid Crystal on Silicon) microdisplay with full HD resolution (1920 x 1080 pixel) and 8 µm pixel pitch leading to an active area diagonal of 0.7” with aspect ratio of 16:9.
The PLUTO SLM is a plug & play phase modulator device and can be addressed with phase functions via standard graphics cards as extended monitor device. The green color channel of the video signal is used for addressing 8 bit gray level patterns (the SLMs native resolution need to be addressed). Addressing can be done using the supplied “Application Software” or standard image viewer software.
HOLOEYE offers different display versions that can be driven with the PLUTO driver unit. The different panel versions are optimized for the use at different wavelength ranges. All versions use fast full digital addressing which assures high reliability and a compact driver unit as basically only two voltages need to be generated.
Applications range from holography, lithography, optical metrology, interferometry, optical tweezers, wave front corrections to phase shifting applications. The high fill factor of the display also ensures a high light efficiency.
PLUTO Spatial Light Modulator – Microdisplay Features
