Title: Optical heterodyne type spectral device
Inventor: SUGANO MASAMITSU
IPC: G01J9/00
Filed: 1989-02-10
Abstract: PURPOSE:To detect a fine light signal with high resolution and high sensitivity by amplifying a beat light signal, generated by mixing a light signal to be measured and a reference light output, after photoelectric conversion, passing the amplified signal through a BPF, and then detecting it by a level meter. CONSTITUTION:A variable wavelength laser which is used as a reference light source 2 includes a frequency component having a band DELTAf1 centering on a single frequency f1, which is variable. Oscillation light beams emitted by a light source 1 to be measured and the reference light source 2 are mixed by an optical mixer 3 to generate the beat light signal. The beat light signal having the oscillation frequency (f) of the light source 1 has a frequency equal to the frequency difference f-(DELTAf1+f1) between both the oscillation light beams. Therefore, the frequency component of the beam light signal is only DELTAf1 when f=f1. Here, the beat light signal is converted by a photodetector 4 into an electric signal, which is amplified by an amplifier 5 and then passed through the BPF 6 having a band similar to that of DELTAf1, so that only the signal component in the band is measured by a level meter 7. This measurement is repeated while the frequency f1 is varied to obtain spectral characteristics of a multi-mode semiconductor laser.
