METHOD FOR COMPENSATING NONLINEARITIES IN A LASER PROJECTION SYSTEM AND LASER PROJECTION SYSTEM COMPRISING MEANS FOR COMPENSATING NONLINEARITIES

摘要

The aim of the invention to homogenize the pixel size and pixel brightness in a laser projection system in which sequences of pixels are projected by deflection with a micromirror. For this purpose, the nonlinearity of the micromirror oscillations is compensated by temporally varying the pixel length. Owing to this compensation, the size and brightness of the projected pixel in this laser projection system is evenly and stably distributed onto a projection surface, thereby improving the image quality of pixels represented on a projection surface, e.g. a screen. A projection system which is constructed according to the above method is especially suitable for miniaturization so that it can be used or installed in a mobile device, for example a mobile phone.
