Title:
METHOD AND CIRCUIT FOR PROCESSING SIGNALS THAT ARE INDICATIVE OF THE SPECTRAL FEATURES OF LIGHT
Document Type and Number:
WIPO Patent Application WO2007118716
Kind Code:
A8
Abstract:
The invention relates to a method and to an electronic circuit for processing signals which as such are indicative of the features or characteristics of the spectral distribution of light which is supplied for spectrometric measurements combined with an LED light source. The problem of the invention is to provide solutions which allow the informative value of spectrometric measurements to be increased. For this purpose, a reference curve for the spectral emission is calculated based on a reference measurement and at least two additional measurements on the same reference, said spectral emission being used as a reference when carrying out measurements of practically any objects. This curve is determined in such a manner that it corresponds to a curve of the spectral emission at a temperature that is outside or far outside the temperature range of the actual temperatures of the LED during the measurements.
