In recent years, with the continuous development of laser projection display technology, people’s choice of electronic display equipment has become more diversified.However, due to the high coherence of the laser used for imaging in the laser projection display device, the speckle phenomenon is more obvious than other display devices, which will greatly affect the user’s actual perception. A color speckle measurement device based on XYZ filter is designed. The computer software is used to control the camera to take speckle pictures under different filters, and calculate the speckle contrast of red, green, blue and white fields.
