Abstract:
1. A method of deconvolution of spectral data comprising: (a) directing light to be analyzed through a collimator onto a linearly variable bandpass filter; (b) directing light from the linear variable bandpass filter onto a plurality of photodetectors arranged in a linear array; each photodetector positioned with respect to the linearly variable bandpass filter to receive a predetermined bandpass; (c) providing a plurality of capacitors each corresponding to a different one of said photodetectors for accumulating a charge proportional to the light energy received by the corresponding photodetector; (d) converting the charge value on each capacitor to digital data and storing said digital data in a pixel array; and (e) correcting the digital data by adding an amount to each stored value corresponding to the proportion of a photodetector's passband captured by adjacent photodetectors, and subtracting an amount from each stored value corresponding to the amount added to adjacent photodetectors.
