Abstract
We have developed a calibration method for synchronizing the autostereoscopic viewing zones displayed by an array of “trixels”, i.e., laser modules with integrated MEMS mirrors. Calibration patterns are projected onto a calibration screen and recorded by a camera. The distortion functions, which map the laser diode driving signals from the time domain to the intensity distributions in the spatial domain, are extracted from the recorded calibration patterns. Unlike conventional autostereoscopic displays, e.g., with lenticular lenses or parallax barriers, the optimal 3D viewing distance of the display can be adapted on-the-fly by transforming the distortion functions using linear operations.
