Optical characterization of shutter glasses stereoscopic 3D displays

A method to characterize time sequential stereoscopic 3D displays which is based on the measurement of the temporal behavior of the system versus grey levels is presented. OPTISCOPE SA, especially designed for precise measurement of luminance and temporal behavior of LCD displays is used. The transmittance and response time of the shutter glasses is first evaluated. Then the grey to grey response times of the display alone are measured. Finally, the temporal behavior of the complete system is modeled and grey to grey crosstalks are deduced. Resulting luminance on left and right eyes of the observer are deduced and compared to integrated measurements using a spectrophotometer. Quality control method using grey level test patterns and imaging luminance meter is deduced and applied to different types of commercial 3D TVs.
