Laser projection is a promising technology for automotive displays. Until now, however, this technology did not find its way into mass production due to limited image quality. One of the image‐degrading factors is the speckle noise. As speckles in an imaging system are subjective and the observed result highly dependent on the observer, there is no standardized way to measure it. We propose a pragmatic approach to quantify speckles in laser projection systems using commercially‐available equipment.
