Abstract

The output power spectrum of a sensor system with n-sensors arranged in parallel has been analyzed theoretically and calculated in detail. The calculated result shows that the noise of the sensors system mainly came from laser random phase noise and the noise level was mainly decided by the coherence time of the laser diode. The theoretical calculation agrees with our observation very well.
