Abstract

The invention discloses an integrating sphere detector which comprises a hollow spherical shell, an incidence hole and a sampling hole. The incidence hole and the sampling hole are arranged on the hollow spherical shell. The integrating sphere detector further comprises a cooling device. The cooling device attached to outside of the hollow spherical shell is used for cooling the hollow spherical shell. The integrating sphere detector is applicable to measurement of various types of optical parameters, especially parameters of light with large divergence angle and high power, such as laser and other high-power light sources. Optical signals obtained are homogenized, and accordingly accurate measurement of optical parameters of multiple light emitters can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to optical parameter testing technology, in particular to an integrating sphere detector. Background technique [0002] In the field of optics, according to the different luminous characteristics and structural characteristics of the measured object, the optical parameters of the following types of light are mainly measured: the first is light with a small divergence angle; the second is light with a large divergence angle and low power ; The third is light with large divergence angle and high power. Optical parameters include light intensity information, spectrum information, and waveform information. [0003] For the first type of light, a photodetector can be used for measurement. The shape of the photosensitive surface of the photodetector is usually planar or conical, which can be used to test parallel light or light signals with small divergence angles. The so-called photosensitive surface Refers to t...
