TRANSMISSIVE
The LC 2012 is our basic Spatial Light Modulator system based on a translucent liquid crystal microdisplay with a resolution of 1024 x 768 pixel (XGA). The device is mainly intended for proof of concepts and education.
Based on a twisted nematic (TN) liquid crystal display simply phase mostly modulation is possible as the twist always causes a coupled polarisation effect (amplitude modulation). The SLM provides a phase shift of about 2 π at 450 nm, about 1.8 π at 532 nm and around 1 π at 800 nm.
The microdisplay and drive electronics are packaged into a compact box for easy integration into optical setups. The LC 2012 is addressed using a standard HDMI interface and brightness and contrast settings can be performed using an USB interface. The LC 2012 Spatial Light Modulator can be used for phase (phase mostly) or amplitude modulation applications dependent on the configuration. The mode depends on the incident polarization and polarizer-analizer settings.
OptiXplorer – Optics Education Kit
The OptiXplorer is an educational kit for both introductory and advanced laboratory courses in optical physics. The main topics covered in the six experimental modules listed below are polarization effects, amplitude modulation, phase modulation and Fourier Optics.
The primary component of the OptiXplorer is a HOLOEYE spatial light modulator (SLM), which is based on a transmissive twisted-nematic LC display with XGA resolution. Additionally a laser module, two rotatable polarizers and some optomechanical components are included in the kit.
The kit is delivered with a bundle of tailored software: The “OptiXplorer” software permits to display various optical functions on the SLM, including self-designed computer-generated holograms (CGH’s). The “PhaseCam” software can be used for interferometric phase measurements. The “DynRon” software is a LabVIEW™ program for diffraction measurements at Ronchi gratings. The SLM device control software is a convenient tool for the adjustment of the SLM’s device settings.
