  • Publication number: 20220268900
    Abstract: Ranging systems with increased accuracy without increased mounting area are disclosed. In one example, a ranging system includes a drive unit, a sensor, a measurement unit and a ranging observation unit. The drive unit outputs a drive signal to cause a light emitting element to emit light to irradiate an object according to a trigger signal. The detects reflection light from the object. The measurement unit measures a delay time between the trigger signal and a timing at which the light emitting element actually emits light. The ranging observation unit calculates the distance to the object based on the timing of the trigger signal, a light receiving timing of the reflection light, and the delay time. The measurement unit charges a capacitor during a period between the trigger signal and the drive signal, and acquires the delay time according to a charging voltage of the capacitor.
