Abstract :
In order to removing the noise of photoelectric detection circuit and solve the problem of optical signal detection under the interference of strong background light and miscellaneous waves. This paper analyzes the sources of photoelectric detection circuit internal noise, and gives the formulas of internal noise, suggests the methods to remove strong background light and miscellaneous waves interference by improving circuit, designs a variable equivalent load photoelectric conversion circuit, and is verified by experiments.
