Light source driving device

Abstract

One example of this is shortening the interval between pulses output from the light source. [Solution] The light source driving device 20 comprises a plurality of capacitive elements 22, a power supply 21, and a discharge control unit 23. The plurality of capacitive elements 22 are arranged in parallel with each other, and each supplies power to the light-emitting element 10 during discharge. The power supply 21 charges the plurality of capacitive elements 22. The discharge control unit 23 individually controls the timing of discharge of the plurality of capacitive elements 22. The light-emitting element 10 is, for example, a light source in a distance measuring device.

Claims

[Claim 1] Multiple capacitive elements are arranged in parallel with each other, and each of them supplies power to the light-emitting element during discharge, A power supply for charging the aforementioned plurality of capacitive elements, A light source driving device comprising a discharge control unit that individually controls the timing of discharge of the plurality of capacitive elements.
