To match the demand of fast detection of high quality holographic grating applied in head-up display, an automatically measuring and recording system is presented. The system is based on step rotation stages with high precision and LabView programming control technology. With this system, automatic measurement on several optical characteristics of transmission phase holographic gratings can be achieved. With different wavelengths and the whole 360 incident angles, the investigation on transmission changing of the holographic grating and analysis on the diffraction characteristics of the holographic grating could be used to optimize the fabrication method on the diffraction efficiency of the holographic grating. Holographic grating 360° measuring set-up helps to figure out how to arrange holographic grating in head-up display as a data base support.
