Abstract

The invention discloses a frequency type photoelectric converter, device and method. The converter comprises a circular base, a cylindrical metal shell, an optical frequency conversion unit, a light-transmitting piece and a base. The optical frequency conversion unit and the light-transmitting sheet are fixed in the cylindrical metal shell; the open end of the cylindrical metal shell is fixedly connected with the base; and the circular base is fixedly connected with the base, is arranged in the cylindrical metal shell and is used for fixing the optical frequency conversion unit. The optical signal intensity is converted into the frequency signal through the frequency type photoelectric conversion device, the illumination intensity is rapidly obtained through the frequency difference, and 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...
