Sensors for detection and spectroscopy

摘要

For multicolor fluorescence detection or spectroscopy with low signal-to-noise ratio and rapid readout, signals from multiple sensors are combined in analog form so that only one signal per fluorescent response needs to be read from a sensor array. The contributions of sensors in the array to a given output signal are programmable, for exclusive selection of the desired information. As the contributions of sensors to output signals are electronically programmed, the energy of the light source can be filtered electronically. Such devices can be programmed in real time for adaptive measurements.
