Abstract

The results of the experimental study of several interferometric spectrum analysers with CCD time integration are presented. The input was performed either by the direct time modulation of the semiconductor laser emission or by the modulation carried out with an acoustooptic modulator. A multichannel spectrum analysis has been also performed. The frequency resolution at 10 Hz was achieved with the 100 ms time accumulation in the 1 kHz frequency range. To increase the SNR an additional analogue processing was carried out by CCD.
