摘要：
A light detecting apparatus receives input light branched and output by a branching device, to calculate transmittance and reflectivity from the input light, acquires a wavelength corresponding to the calculated transmittance and reflectivity to calculate a gain value corresponding to input light intensity, acquires a driving current value corresponding to a calculated gain value and an acquired wavelength, and outputs an acquired driving current value.
