WebOptical Frequency Domain Reflectometry (OFDR) is an optical measurement method using the coherence of laser light. OFDR can perform remote, non-contact, and high-precision measurement in various fields. Wavelength Swept Light Source for OFDR Our company has developed a wavelength swept light source for OFDR. WebBy using chirped fiber Bragg gratings, mode-locked optical pulses can be made that appear as continuous wave signals that completely fill the mode-locked pulse period. In addition, optical amplifying systems can be configured that completely circumvent the conventional limitation imposed by short pulse gain saturation.
