Abstract: Present invention provides an imaging optical radiation measurement device, including a chassis, which is equipped with an optical lens. The chassis includes a first array detector, a spectral measurement module, a color filter wheel set, a light path switching device, and a signal processing and output unit. The color filter wheel set has a plurality of apertures, and two or more pieces of color filters are set in the apertures; the measured light beam passes through the optical lens and enters the chassis, and a light path switching Device will be measured beam at the same time or successively switched to two or more measurements in the optical path. The present invention also provides a display light field radiation measurement method to realize the measurement of hyperspectral information of the display to be measured.

Abstract: The present invention provides measurement methods and devices for near-eye displays. One of the measurement methods and devices of the present invention uses a surface array photoelectric sensor without an imaging lens and a transmission mechanism to obtain an exit pupil parameter of the near eye display to be measured, and uses a surface array photoelectric sensor without an imaging lens, a transmission mechanism and an imaging mechanism to obtain an optical axis position of the near eye display to be measured. Another measurement method and device of the present invention controls the transmission mechanism by means of a programmed control system, so that the near-eye display to be measured and the optical receiving screen undergo relative motion, and the pupil exit parameter of the near-eye display to be measured is obtained by observing and analyzing the light spot on the optical receiving screen.

Abstract: An integrating sphere photometer spectral response measurement method and system. The system comprises an integrating sphere photometer and three or more reference light sources having different peak wavelengths. The integrating sphere photometer consists of an integrating sphere (1) and a broadband photodetector (2), and the broadband photodetector (2) is mounted on the sphere wall of the integrating sphere (1). Emergent light of the reference light sources is incident to the integrating sphere (1); the total spectral radiation flux Pi(?) (i=1, 2, . . . n) received by an integrating sphere photometer system is acquired; the response Mi (i=1, 2, . . . n) of a photometer of mixed light in the integrating sphere (1) is read by means of the broadband photodetector (2); an equation set is established; and the spectral responsivity Srel(?) of the integrating sphere photometer is obtained by means of numerical solution.
