Sažetak
The infrared radiation measurement system based on the cooled PbS photoconductive detector with a preamplifier and a mechanical chopper in the moisture meter with one beam is designed by the authors and analyzed in this paper. Two pairs of the band pass near infrared (NIR) filters, the first one being 1800nm, and the second one 1940nm, are embedded in the wheel which is rotated by the motor. The mechanical chopper has a double function. First, the reference NIR radiation which is not absorbing for water and narrow band at 1940nm which is absorbing for water extracts from the incident radiation generated by the source. Second, the reference and the absorbing beam are mechanically modulated by the signal of designated frequency and directed to the tested sample. So in the frequency specter of the signal produced by the PbS detector consequent upon the reflected radiation from the sample contains information about moisture content. The basic aim of this paper is to carry out a frequency analysis. The final aim is to develop an optimal optoelectronical measuring system for the infrared moisture meter for practical use but with some specific substances in the firs place. The overall results can be kept in the numerous variety applications later.
