Research output: Patent


The system has a silicon slice (3) clamped between molybdenum sheets (4), and an optical fiber (51) made of quartz glass. A multi-mode fiber is connected with a demodulator. The demodulator demodulates reflecting wavelength of reflecting light sent by a fiber grating temperature sensor into a temperature signal to obtain real-time information of the temperature in a thyristor copper shell. The demodulator transmits demodulated data to a background computer via a network line
