Abstract
A light source apparatus is provided with the emission section in which a plurality of vertical-cavity surface-emitting laser light-emitting elements is arrayed, the driving circuit section that causes the plurality of light-emitting elements of the emission section to emit light, the temperature detection section that includes a plurality of temperature sensors arranged to detect the temperature of the emission section, and a control section. The control section is configured to, during an emission target period when the light-emitting elements of the emission section are driven by the driving circuit section, correct a detection value from each of the plurality of temperature sensors by using a correction value set for each of the temperature sensors.
