Noise
Measurement——Silicon Photodetector |
|
Noise measurement adopts silicon
photodetector to measure the laser beam after attenuation, laser
optoelectronic signal shows on oscilloscope via adjust variable
attenuator, and noise signal shows by adjust oscilloscope. Laser
system output power stability can be judged according to noise
signal. |
