INTELLIGENT PHOTONIC MEASUREMENT FOR SPECTROPHOTOMETERS

Rainer Riesenberg, Andreas Wuttig

Abstract

Experimental results of intelligent adaptive detection made with spectral sensors are presented.
Firstly for a commercial detector array spectrometer the single entrance slit is replaced by a slit array. Differently patterned one-dimensional arrays are used. There are switched and fixed versions of arrays. An improvement of the detected signal and the signal-to-noise-ratio by the factor 10 has been achieved.
Secondly the measured noisy signal is compared with known expected signals. Weak signals can be detected with an high probability and thus an increased sensitivity.
