the q8344a makes use of a fourier spectrum analysis approach basedon a michelson interferometer. because of this, the q8344a canmeasure optical coherence that cannot be obtained directly usingdiffraction-type optical spectrum analyzers which usemonochromators to make their measurements.
the features of this analyzer make it very effective for theevaluation of laser diodes used in optical data storage equipment,fiber optic gyroscopes, and related applications. the q8344a has abuilt-in he-ne laser that functions as the wavelength reference andensures the wavelength measurement accuracy is maintained within+/- 0.1 nm (at 1.3 micro m). because of this internal referencesource, no calibration is needed, thereby allowing this analyzer toprovide long-term repeatable measurements.
this instrument is exceptionally well suited to the measurement ofcoherence length of ld and led optical sources operated incontinuous wave mode only.
