CIRCUIT ARRANGEMENT FOR CREATING LIGHT AND TEMPERATURE DEPENDANT SIGNALS, PARTICULARLY FOR AN IMAGING PYROMETER

摘要

The invention relates to a circuit arrangement for creating light and temperature dependant signals, comprising a plurality of first and second sensor elements that generate a plurality of first and second electric signals as a function of received electromagnetic radiation. The first sensor element are designed to generate the first electric signals as a function of electromagnetic radiation from a first wavelength range (62) comprising at least a large part of the visible light. The second sensor elements are designed to create the second electric signals as a function of electromagnetic radiation from a second wavelength range (64) comprising mainly infrared radiation. According to an aspect of the invention, the first wavelength range (62) overlaps the second wavelength range (64), and thus also contains infrared radiation. The new circuit arrangement is preferably used for an imaging pyrometer.;COPYRIGHT KIPO & WIPO 2010
