ABSTRACT:
A system for time resolved spectroscopy comprises a CCD device arranged to receive a time varying spectrum. Time resolved spectroscopy is the analysis of a spectrum that varies with time due to any cause. The variation with time of the spectrum may be due, for example, to (i) changes of the spectrum from a given sample space with time (such as due to emission decay); and (ii) changes in the spectrum as successive portions of a sample space are sampled (such as laser scanning microscopy). The CCD device comprises an array of photosites arranged to detect the time varying spectrum and to produce signal charge representative of the spectrum, and one or more CCD multiplication registers arranged to receive the signal charge and to provide charge multiplication. An enhancement of speed and sensitivity is given by a storage area which receives the signal charge in parallel from the array of photosites to provide the charge in serial to the one or more multiplication registers.
