| Abstract | A light source module including: an LD element outputting a laser light; a lens receiving the laser light and outputting a focused light; an optical filter having transmission wavelength characteristics, inputting the focused light, and outputting a transmitted light and a reflected light based on the transmission wavelength characteristics, a light-receiving element detecting the reflected light which passes thorough the lens and generating a detection signal; and a control unit configured to control an output wavelength of the LD element based on the detection signal. |
