可调谐光源 meaning in English

tunable optical generator

The demodulation method of fiber grating is the key method of fiber grating sensor . the main demodulation method includes : grating matching method , tunable fabry - perot cavity method , non - balance mach - zehnder interferometer method and tunable narrow - band light source method . the tunable fabry - perot cavity method is discussed in detail , and a demodulation system based on dsp is put forward
