SIGNAL LIGHT MANUFACTURING APPARATUS FOR USING OPTICAL FIBER AND ROTATION SENSING APPARATUS

摘要

PURPOSE: A signal optical generation device using optical fiber for increasing the accuracy of rotation measurement is provided to reduce central wavelength variation about temperature variation and pump power. CONSTITUTION: An optical fiber(130) is gain medium. A source light source(100) radiates the pumping light. A stabilizing unit(120) stabilizes the peak wavelength of the signal beam through the compensation of the peak wavelength rate of the signal beam according to the temperature change of the optical fiber. An optical coupler transfers the radiated pumping light to the optical fiber. The optical coupler outputs the signal beam turning back around in the optical fiber.
