SPECTROMETRY APPARATUS AND SPECTROMETRY METHOD

摘要

According to the present invention a spectrometry apparatus includes: an optical filter device in which two or more filters are provided to filter incident light; an optical sensor device in which two or more optical sensors are provided to be capable of corresponding to the two or more filters so as to convert the filtered light into a charge to be outputted; and a digital signal processing unit that performs digital signal processing on an output signal of the optical sensor device to recover spectrum data on the incident light, and having at least one of the two or more filters being a random transmittance filter. According to the present invention, the resolution of the recovered optical signal is improved and recovery accuracy is improved.
