| Popis: | This paper focuses on the design of a temperature sensor for use in a nanosatellite. The system uses a light source whose wavelength can be tuned in a moderate range and a Fiber Bragg Grating (FBG). The interrogation system incorporates a temperature controller, a laser current controller, and a compact signal processing system. A climatic chamber is used to calibrate the sensor and obtain the relationship between wavelength and temperature. Experimental results show a temperature range from 50°C to 100°C with a sensitivity of 30pm/°C, and the feasibility of achieving ranges up to 400°C using an FBG with a sensitivity of 10pm/°C is studied. |
