Abstract

A spectroscopic sensor that applies lights in a wavelength band containing plural wavelengths to an object and spectroscopically separates reflected lights or transmitted lights from the object using plural light band-pass filters that transmit the respective specific wavelengths and plural photosensor parts to which corresponding transmitted lights are input based on output results of independent photosensors. The spectroscopic sensor may be integrated in a semiconductor device or module by integration using a semiconductor process and downsizing may be realized.
