MODULAR LUMINESCENCE-BASED MEASURING SYSTEM USING FAST DIGITAL SIGNAL PROCESSING

摘要

the invention relates to an optical system (11) and electronic (29, 37, 51, 55, 59) incorporated, based on the luminescence, which is used to measure the temperature or other parameter based on the time of breakdown of a luminescence sensor (25).to this end, a low noise amplifier and high bandwidth (31) applies a signal detected by a luminescence decay digital system (29, 37, 51), which acquires the signal and processes in order to determine the characteristics of the time of disintegration, i was then correlated with temperature or other parameter to be measured.the operation of the digital signal processing technique of numerical curve fitting. a luminescent material is preferred to measure the temperature of a material of yttrium gallium garnet doped with chromium. all optical parts and electronic measurement system on a single card to hold circuits (131).
