ABSTRACT:
An analyzing method and system includes projecting light onto a specimen, detecting an optical spectrum from the specimen, dividing the detected optical spectrum by a predetermined time interval, applying a weighting vector and a gain and offset vector to the divided spectra to generate a resolution vector, quantizing an analog signal of the resolution vector to a digital signal, and applying a synthesis vector to the quantized spectra to restore the quantized spectra to a size of the optical spectrum. A spectrum having a large amplitude difference is temporally divided and is analyzed by applying different resolutions to individual time intervals. Spectral portions of the spectrum having relatively small peak amplitudes are selected as a region of interest (ROI) to be modified.
