DIMOS - numerical simulation of LCDs

The first commercial software for numerical modeling of display systems with LCDs in 1, 2 and 3 dimensions, DIMOS, is now being marketed by DM&S. Technical support, enhancements and maintenance are still provided by Dr. Henning Wöhler and Dr. Johannes Duyster.In case of interest ask for a free-of-charge DIMOS evaluation version.


High-resolution BSDF/BRDF-measurement and evaluation finally made affordable ! 

DM&S has introduced a novel approach on the SID 2004 Conference in Seattle for measurement and evaluation of display scattering. The BSDF-Meter, the implementation of this method, is now available from DM&S for simple and effective measurement and evaluation of light scattering in general (bidirectional scattering distribution function, BSDF) and for application to electronic displays specifically.  

The method is based on the measurement of the lateral distribution of reflected luminance with an imaging detector. After numerical transformation of the measured luminance distribution we obtain the characteristics of the BRDF/BSDF of the sample with high directional resolution within a limited range of inclination angles centered about the specular direction. Due to the absence of moving parts the method exhibits only little sensitivity with respect to variations of the geometry parameters and is thus very robust.

Reference-Ticker available

This novel programmable light-source emulates a single line of a matrix-organized electronic visual display with an exactly controlled timing. It is designed for performance checking and calibration of measurement devices for motion-blur analysis and for research of perception of motion by the human visual system. The complete range of display screens from hold-type to impulse-type display can be emulated.
