| Abstract: | The paper investigated the noise of optoelectronic detectors, analyzed the noise Voltage and current in optoelectronic detectors, and discussed a method of reducing the noises. According to the influence factors of the detector noises, we analyzed the existent shortages in the common electric examination circuit, and designed a kind of excellent electric examination circuit. The circuit adopted a method of reducing the bandwidth of the circuit to lessening the noises and strengthening the signal noise ratio of the system and the detectability of the optoelectronic detectors. |
