A projection optical system includes a laser diode; a laser diode module having a plurality of the laser diodes one-line arranged; a light projecting lens to adjust spread of light emitted from the respective laser diodes; and an optical deflector to deflect light passing through the light projecting lens and irradiate a target with the deflected light. The laser diodes emit light such that the light spreads at a first angle in a first direction and spreads at a second angle being wider than the first angle in a second direction being perpendicular to the first direction. The laser diode modules are disposed such that an arrangement direction thereof coincides with the first direction and they are placed along the second direction and shifted in position relative to each other in the first direction. The light projecting lenses are disposed with corresponding to the laser diode modules.

Projection optical system and object detection device

A vehicle power-supply control device has a battery charger that converts an externally-supplied AC voltage into a DC voltage used to charge a vehicle high-voltage battery, a low-voltage power generator that converts the DC voltage output from the battery charger into a DC voltage used to drive a vehicle auxiliary machine, and a controller that controls the battery charger and the low-voltage power generator. The battery charger includes a power factor correction circuit that corrects a power factor of the AC voltage and a first DC/DC converter that generates a predetermined DC voltage based on an output of the power factor correction circuit. The low-voltage power generator includes a second DC/DC converter that steps down the DC voltage output from the battery charger and a synchronous rectifier that rectifies an output of the second DC/DC converter in synchronization with a switching operation of the second DC/DC converter.

A laser radar device has a light projection part that projects light to a monitoring area outside a vehicle from a vehicle interior through a glass surface, a light receiving part that is placed a given distance away from the light projection part in a substantially horizontal direction to receive reflected light from an object outside the vehicle in the light projected by the light projection part through the glass surface, a measuring part that measures the distance to the object in the monitoring area based on timing when the light projection part projects the light and timing when the light receiving part receives the reflected light, and a light-projection shielding part that shields the light projected to an outside of the monitoring area in the light projected by the light projection part.
