Paper Abstract

This paper studies the influence of radiation thermometer optical system properties on the total radiating energy upon an optoelectronic detection device when the measuring distance ins variable. The first pat is a brief analysis of characteristics of concentrating IR radiation through the thermometer objective. The sources used are smaller, larger or equal than the detection device field of view. When using the equal sources, the specific shape of the measuring area was taken into account, and included in the total field of view. Catoptric objective was used. In addition, this paper present the main error sources on concentrating IR radiation on the detection device in following conditions: the calibration is performed at a finite and infinite distance, the radiation source is assumed to be perfectly Lambertian and the objective is catoptric.
