The Sycatus A0070A Optical Frequency Analyzer fills a solution for the measurement of FMCW LiDRA lasers. FMCW LiDAR is a promising distance sensing technology due to its high sensitivity, excellent tolerance to background radiation and inter-LiDAR interference and less risk to eye safety. FMCW LiDAR uses a laser beam with triangular optical frequency modulation. \
The optical frequency modulation rate (Hz/s) is the key parameter for distance measurement. The laser beam is generally generated by direct modulation of a semiconductor laser. The optical frequency modulation rate of the semiconductor laser is not necessarily constant and varies transiently due to temperature changes caused by modulation. In addition, direct modulation of a semiconductor laser modulates not only the optical frequency but also the optical intensity.
The optical frequency modulation characteristics must be measured in the time domain without the influence of intensity modulation. A0070A Optical Frequency Analyzer shows the real-time optical frequency modulation waveform like an oscilloscope. SYCATUS' unique method enables measurement without being affected by optical intensity modulation. A0070A's accurate and easy measurements accelerates the development and manufacturing of lasers for FMCW LiDAR.
