Abstract

Compared with the traditional panel display, the head-mounted display (HMD) is a new technology. When using an HMD, it occupies a significant portion of the eyes’ natural field of view (FOV). Thus, it is necessary to ensure the imaging quality of an HMD, which requires accurate measurement and evaluation. Based on the measurement of panel display, this paper proposes a kind of luminance and chromaticity measuring equipment for HMD by combining an optical fiber spectrometer with a translation platform. The equipment measures various parameters such as brightness, chromaticity, contrast, color gamut, eyebox, etc. To prove the validity of the equipment, several HMDs with different luminance are used for multiple measurements. The final results show that the brightness stability of the equipment reaches 2%, and the chromaticity stability reaches 0.002, which fully meets the measurement requirements of HMD. This equipment has certain reference value for HMD production and testing.
