Abstract
According to one embodiment, an optical sensor is disclosed. The sensor includes a bandpass filter which transmits light in a first wavelength band including a first wavelength, and includes a transmittance distribution of the light in the first wavelength band. The transmittance distribution has a maximal value at the first wavelength. The sensor further includes a notch filter which blocks transmission of light in a second wavelength band including a second wavelength shorter than the first wavelength, and includes a transmittance distribution of light in the second wavelength band. The transmittance distribution has a first minimal value at the second wavelength.
