    Abstract - (Show below) - (Hide below)

    IEC 62906-5-2:2016(E) specifies the standard measurement conditions and measurement methods for determining the monochromatic speckle contrast of laser display devices (LDDs). The LDDs may include hybrid types using both a laser or lasers, and spontaneous emission-based light sources, such as LEDs.
    NOTE: The monochromatic speckle contrast measurements do not include image quality issues.
