Abstract

The invention discloses a frequency-type photoelectric converter, device and method. The frequency-type photoelectric converter comprises a square base, a light-transmitting sheet, an optical frequency conversion unit and a metal cover plate; the optical frequency conversion unit is fixed in the square base; and the metal cover plate and the light-transmitting sheet are respectively and fixedly connected with the square base. According to the invention, the light signal intensity is converted into the frequency signal, and the illumination intensity is rapidly obtained through the frequency difference, so that the influence of dark current on measurement is avoided.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a frequency-type photoelectric converter, device and method. Background technique [0002] A photoelectric converter is a detector made of the photoelectric effect of materials, which mainly uses the photoelectric effect to convert optical signals into electrical signals. Since the discovery of the photoelectric effect, photoelectric conversion devices have developed by leaps and bounds and have been widely used in various industries. [0003] Currently commonly used photoelectric effect conversion devices include photoresistors, photocells, photomultipliers, photodiodes, phototransistors, etc., and these photoelectric conversion devices are all based on semiconductor materials. The light detection capability depends on the intrinsic band structure properties of the material, such as the absorption coefficient, and on several characteristics of the semiconductor junction, such as doping p...
