A laser radar device includes: a projection part repeatedly performing processing of projecting measurement light that is of a pulsed laser beam to a predetermined monitoring area in a measurement period having a predetermined first length, the processing being repeated in c cycles (c&#x2267;2) in a detection period having a predetermined second length; a light receiver including n1 (n1&#x2267;2) light receiving elements and receiving reflected light of the measurement light in directions different from one another; a selector selecting light receiving signals of the n1 light receiving elements in each measurement period and output n2 (n2&#x2267;2) light receiving signals; a sampling part sampling the light receiving signals output from the selector s (s&#x2267;2) times every time the measurement light is projected; and a detector performing processing of detecting an object in a detection-period-based period based on sampling values.

Laser radar device and object detection method

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.

Laser radar device placed on glass surface of vehicle

An object sensing device has a radiation part that radiates an exploring wave forward, a sensing part having a first sensing element and a second sensing element, wherein the first sensing element and the second sensing element sense a reflected wave of the exploring wave radiated by the radiation part; and a determination part. The determination part determines a rainfall state ahead based on an intensity of the reflected wave sensed by the first sensing element. The determination part determines existence or non-existence of an object positioned forward based on an intensity of the reflected wave sensed by the second sensing element. A visual-field restricting member is disposed in front of the first sensing element. The visual-field restricting member causes a visual field, in which the first sensing element senses the reflected wave, to differ from a visual field, in which the second sensing element senses the reflected wave.
