Abstract: Laser based video projectors (LBVP) are relatively new on the scene ofvideo display. LBVPs consist of laser beams that are scanned and synchronously modulated. An important characteristic of the LBVP is the very short lifetime of the pixels. Each pixel produces light only for the very short time during which the laser beam passes on it. The short transients make the measurement of a LBVP image’s properties more difficult to obtain in comparison to conventional display devices. The validity of the results is even questionable when conventional methods are used to measure the characteristics of LBVP images. This paper presents an alternative method for the characterization of brightness and contrast of LBVP images that is expected to provide more reliable results.
