Title:
SPECTRAL SENSOR, SPECTRAL SENSOR MODULE, SENSOR APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/221663
Kind Code:
A1
Abstract:
Provided in the present application are a spectral sensor, a spectral sensor module, a sensor apparatus and an electronic device. The spectral sensor comprises a spectral chip and an optical assembly, wherein the spectral chip comprises a light modulation layer and a photoelectric detection layer; the light modulation layer is arranged, in a sensing path of the photoelectric detection layer, on one side of a light incident face of the photoelectric detection layer, and comprises a modulation unit used for modulating incident light; the optical assembly is arranged in a sensing path of the spectral chip; and the optical assembly at least comprises a diaphragm; the incident light passes through the diaphragm to form a light spot which irradiates the light modulation layer, and the light spot covers at least one modulation unit of the light modulation layer; or, the optical assembly comprises a light homogenizing member and a diaphragm, and the incident light passes through the light homogenizing member and the diaphragm to guide an optical signal to the upper surface of the light modulation layer; or, the optical assembly comprises a light homogenizing device and a lens, and the incident light passes through the light homogenizing device and the lens so as to be guided to the surface of the spectral chip at a set incident angle and in a uniform light intensity manner. In addition, the spectral sensor module at least comprises a spectral sensor and a circuit board. The spectral sensor provided in the present application can improve the photoelectric performance, for example, improve the accuracy and stability of spectrum recovery, etc.
