Laser illumination for projection introduces undesirable speckle artifacts that must be measured accurately and suppressed. A useful and accurate standardized method to measure and quantify the effect has been elusive. This paper describes work that investigates the most significant measurement setup parameters affecting correlation between manufacturer measurements and observed speckle image quality.
