Abstract :
A SiC UV detector integrated with and onboard solar cell and an oscillator circuit is used to monitor UV emission from an acetylene torch that simulates conditions inside a jet engine. UV emission intensity can be used to monitor the efficiency of combustion in jet engines and other related applications and in chemical sensing based on flame analysis. The oscillator circuits converts the UV detectorpsilas output to a 60 MHz signal that is frequency modulated by the detected UV intensity. The signal is then directly transmitted to an external receiver. The wide-spectrum optical emission inside the engine is used to power the wireless sensor using the solar cell. A tunnel diode circuit is developed and is used to shift the voltage levels from 0.6 Volts to 3.1 volts or higher wherever is needed.
