摘要:
A beam irradiation apparatus includes a light source which outputs a laser beam, a convergent lens into which the laser beam output from the light source is entered, and a scanning portion which makes the laser beam transmitted through the convergent lens scan on a target region. In the beam irradiation apparatus, the laser light source is arranged such that a pn junction surface of a laser chip is parallel with the vertical direction. Length of the laser beam in the vertical direction on the target region is set by length of a light emitting portion of the laser light source in the vertical direction. Further, a wavefront aberration of the convergent lens with respect to the laser beam is set to be 0.15 λrms or less.

A mirror actuator includes a turning axis for turning a mirror; a support section for supporting the turning axis so as to be capable of turning; and a sliding contact member that is arranged on the turning axis and is opposed to the support section in a direction parallel to the turning axis with a predetermined clearance from the support section. The turning axis is biased in one direction parallel to the turning axis. This biasing causes the sliding contact member to contact the support section.

A beam irradiation device includes a laser light source which emits laser light; an actuator which causes the laser light to scan a targeted area; and a wiring portion which supplies a drive signal to the actuator. The actuator includes a first movable portion which is pivotally movable around a first axis, an optical element which is disposed on the first movable portion, and on which the laser light is entered, and a first coil which is disposed on the first movable portion. The wiring portion includes a wiring member which is electrically connected to the first coil, and has a spring property in a flexing direction. The wiring member is disposed at such a position as to urge the first movable portion toward a first scan start position around the first axis, using the spring property.

A laser radar according to an embodiment of the invention includes a beam irradiation head which emits a laser beam and a control circuit which controls the beam irradiation head to perform scan in a two-dimensional direction with the laser beam. In the laser radar, the beam irradiation head includes a laser beam source; a mirror to which the laser beam emitted from the laser beam source is incident; and a driving mechanism which rotates the mirror in first and second directions about a first rotating axis and a second rotating axis perpendicular to the first rotating axis respectively. The control circuit controls the rotation of the mirror in the first direction and the second direction such that a scan region of the laser beam becomes a rectangular shape.

A projection optical system is provided with a diffractive optical element which converts laser light emitted from a laser light source into light having a dot pattern by diffraction and projects laser light onto a target area with a predetermined dot pattern. The diffractive optical element is formed in such a manner that the density of dots in a peripheral portion of a target area is set larger than the density of dots in a center portion of the target area. With this arrangement, in performing a pattern matching operation for a segment area in the vicinity of the outer side of the target area, the number of dots to be included in the segment area increases. This enhances the precision in the pattern matching operation.
