First Claim
Patent Images
1. A spectral measurement device comprising:
- an optical band-pass filter section that has first to n-th wavelengths (n is an integer of 2 or more) having a predetermined wavelength width as a spectral band thereof;
a light receiving section that receives light from the optical band-pass filter section;
a correction operation section that performs an operation to correct a reception signal obtained from the light receiving section; and
a signal processing section that executes predetermined signal processing based on the reception signal corrected by the correction operation section,wherein the correction operation section corrects the reception signal based on a change in a spectral distribution of the reception signal.

Abstract
A spectral measurement device includes: an optical band-pass filter section that has first to n-th wavelengths (n is an integer of 2 or more) having a predetermined wavelength width as a spectral band thereof; a correction operation section that corrects a reception signal based on an output optical signal from the optical band-pass filter section; and a signal processing section that executes predetermined signal processing based on the reception signal corrected by the correction operation section that corrects the reception signal based on the change in the spectral distribution of the reception signal.
