Tuning Parameters of IR-sensor in Control Systems

This paper describes the method of practical tuning parameters of a built-in infrared (IR) sensor with matrices of photosensitive elements aimed to register light pulses in order to control different automatic systems. The method searches the optimal values of the low and high frequencies of the bandpass filter and the sampling period of the switcher using the genetic algorithm of optimization. The optimality criterion is based on comparison of the bandpass filter with the optimal filter. The experimental results have shown possibility to significantly improve signal-to-noise ratio during pulse detection and its amplitude measurement.
