摘要： A beam irradiation device includes a light source for emitting laser light, an actuator for displacing a propagation direction of the laser light in accordance with a control signal, and a scan expansion lens for increasing a swing width of the laser light to be generated by the actuator. A spectral element is arranged between the actuator and the scan expansion lens. The spectral element allows at least a part of the laser light to be incident from the actuator to transmit, and reflects at least a part of the laser light to be incident from the scan expansion lens. The beam irradiation device further includes a light detector for receiving the laser light to be reflected on the spectral element to output an electrical signal.

摘要： A light refracting element formed in parallel plate shape is attached to a support shaft of a mirror holder, a semiconductor laser and a PSD are disposed at positions between which the light refracting element is sandwiched. The light refracting element is rotated by rotation of the mirror holder, and whereby a laser beam irradiation position is changed on a light acceptance surface of PSD. The laser beam irradiation position on a light acceptance surface corresponds to the mirror rotation position, so that the mirror rotation position and a laser beam scanning position in a target area can be detected based on an output from the PSD.

摘要： An attachment lens is arranged in a stage subsequent to a scanning lens. After a laser beam is converged by the scanning lens, the laser beam is converted into a parallel beam by the attachment lens. When the scanning lens is displaced in a direction perpendicular to an optical axis of the laser beam, a traveling direction of the laser beam is bent by a predetermined angle immediately after the laser beam passes through the scanning lens. Then, the traveling direction of the laser beam is further bent by a predetermined angle in the same direction by the passage of the laser beam through the attachment lens. Accordingly, a final swing angle of the laser beam outgoing from an outgoing window is increased by a swing angle imparted by the attachment lens compared with the case where the attachment lens is not arranged. One of lens surfaces of the attachment lens is formed in a toroidal surface, which allows the laser beam to have a long outline in a vertical direction.
摘要翻译：附着透镜布置在扫描透镜之后的阶段中。在激光束被扫描透镜会聚之后，激光束被附着透镜转换成平行光束。当扫描透镜在与激光束的光轴垂直的方向上移位时，激光束的行进方向在激光束通过扫描透镜之后立即弯曲预定角度。然后，激光束的行进方向通过激光束通过附着透镜而沿相同方向进一步弯曲预定角度。因此，与未配置附件镜头的情况相比，从出射窗口射出的激光束的最终摆动角度增加了由附着镜头施加的摆动角度。附着透镜的透镜表面之一形成在环形表面中，这允许激光束在垂直方向上具有长轮廓。

摘要： A scan trajectory of a laser beam is controlled based on external signals each related to a driving direction and a driving speed, a result obtained by detection of an obstacle, and signals related to distances to the obstacle. For example, at the time of a right turn, a scan trajectory for increasing scan frequency on a portion shifted in a right-turn direction from a center axis in a driving direction is set. At the time of high-speed driving, a scan trajectory for increasing scan frequency on a center portion in the driving direction is set. When the obstacle is detected at a position corresponding to a distance shorter than a threshold distance, a scan trajectory for increasing scan frequency in the vicinity of the obstacle is set. Detection of the obstacle and monitoring of a state thereof are adequately and smoothly performed at the time of changing of the driving direction, the time of high-speed driving, and the time of detection of the obstacle.
