| Abstract: | The composition of the infrared detector noise is analyzed. The cause of noise formation is expressed. A low noise multiple switch circuit is designed to measure the noise of four quadrant optoelectronic detector automatically. To reduce the interferences inducted by other components in the circuit, the circuit is optimized. The experiment result shows that the circuit and measurement method have many advantages. The measurement error is not higher than 2%. And it can be applied in other kinds of multi-quadrant detector noise measurement. |
