摘要： A method for optical and electrical signal processing of a multi-heterodyne signal generated by a multi-mode semi-conductor laser, for a system comprising two laser sources and an sample interaction unit. At least the beam of one of the laser passes through said sample interaction unit before being combined on a detector. The first laser is tuned (40=>42) by an amount keeping the tuning result within the available detector bandwidth (55). Then the second laser is roughly tuned by the same amount as the tuning of the first laser to bring back the signal to the vicinity (48) of the original place in the RF-domain and within the bandwidth (55) of the detector. The tuning steps are repeated with different value of mode spacing for reconstructing the sample spectrum and provide a high resolution image of the dip (41) absorption line (40).

摘要： A phase-diverse coherent optical spectrum analyzer is presented. An optical receiver receives a first input signal and a second input signal, and produces at least a first output signal, a second output signal, and a third output signal based on mixing the first input signal and the second input signal. A processing unit isolates heterodyne components from the first output signal, the second output signal and the third output signal, wherein the heterodyne components comprise a first signal and a second signal that represent the phase-diverse nature of the optical mixing process. Phase diversity of the heterodyning between the first input signal and the second input signal is achieved by the coherent optical spectrum analyzer.

摘要： An optical image measuring apparatus capable of effectively obtaining a direct current component of a heterodyne signal which is composed of background light of interference light is provided. The optical image measuring apparatus includes: an optical interference system in which a light beam from a light source is divided into signal light and reference light by a beam splitter, a frequency of the reference light is shifted by a frequency shifter, and the signal light propagating through an object to be measured and the reference light reflected on a mirror are superimposed on each other by the beam splitter to produce interference light; beam splitters for dividing the interference light into interference light beams; shutters serving as an intensity modulating unit for modulating intensities of the respective interference light beams at predetermined intervals; CCDs for receiving the respective interference light beams whose intensities are modulated and outputting electrical signals; and a signal processing portion serving as a calculating unit for calculating an intensity of the direct current component corresponding to the background light of the interference light based on the outputted electrical signals.
