Using DVI/HDMI ports of standard PC graphics cards, the Spatial Light Modulator can be used just like an external plug & play monitor (e.g. The optical function or information to be displayed on HOLOEYE Spatial Light Modulators can be taken directly from an optic design software or an image source and can be transferred by a computer interface. In addition the reflectivity of the aluminum mirror is limited (dependent on wavelength). Some part of the light is also scattered and absorbed at the interpixel gaps. The reflectivity is not 100% as some of the light is diffracted into higher orders due to the grating like structure of the pixel matrix.
Reflectivity: Amount of light which is directly reflected (0-order of a non-addressed display).The actual response time of the liquid crystal is determined by the properties of the used liquid crystal material, the thickness of the LC layer, the used drive sequence / calibration (the actual voltages applied to a pixel) and temperature.įor phase SLMs the response time typically is below the Input frame rate. Response Time: The response time is defined as the switching time from 10% to 90% and from 90% to 10 % (rise and fall time).Input Frame Rate: Addressing speed of the input signal (typically DVI / HDMI video frame rates of 60 Hz for monochrome applications).Addressing: Number of gray levels / phase levels that can be addressed.Active Area: Size of the actual adressable/usable display area.There are gaps between the pixels at which the incident light is scattered. Fill Factor: Surface area of the display which can actively used.
In a twisted cell, the orientation of the molecules differs by typically 45°/90° between the top and the bottom of the LC cell and is arranged in a helix-like structure in between. HOLOEYEs SLMs are based on vertical aligned nematic (VAN),parallel aligned nematic (PAN) or twisted nematic (TN) microdisplay cells. The addressed gray level is now converted into a phase level. As LC molecules also show optical anisotropy this tilt changes the refractive index of the LC molecules (for suitable incident polarization, dependent on device version) which causes a modified optical path length within the LC cell. This voltage leads to a variable tilt of the LC molecules due to their electrical anisotropy. A certain gray level represents a defined average voltage across the LC cell. The use of LC materials in SLMs is based on their optical and electrical anisotropy. HOLOEYE´s Spatial Light Modulator systems are based on translucent (LCD) or reflective (LCOS) liquid crystal microdisplays. Spatial light modulator (SLM) is a general term describing devices that are used to modulate amplitude, phase, or polarization of light waves in space and time.
