The problems of exterior, relative, and absolute orientation are analysed using Plücker lines with the aim of finding constraint equations less complex than those in conventional use, and thus faciliting more accurate computation of the unknowns. The equations of perspective projection are avoided by modelling image-forming rays as 3-D lines. An unusual(More)
Speckle can seriously degrade image quality in laser-illuminated projection displays. Various solutions appropriate to small microdisplay-based projectors are presented. Illumination optical system and projection optical system design are discussed in order to better understand the critical constraints of size, power consumption, optical efficiency, and(More)
