Spectrometer and Method for Measuring spectrum using the same

摘要

The present invention discloses a spectroscope including a first unit spectral filter which absorbs or reflects light of a partial wavelength band of an incident optical spectrum of an object, a second unit spectral filter which absorbs or reflects light of a wavelength band which is different from the partial wavelength band, a first photodetector for detecting a first optical spectrum passing through the first unit spectral filter, a second photodetector for detecting a second optical spectrum passing through the second unit spectral filter, and a processing unit for performing a reconstruction function of the incident optical spectrum of the object from the spectrum of the light detected by the first photodetector and the second photodetector. Accordingly, the present invention can easily perform 2D integration with a simple process at low costs.
