摘要	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.
其他摘要	投影光学系统包括激光二极管;激光二极管模块，具有多个单线排列的激光二极管;一种光投射透镜，用于调节从各个激光二极管发出的光的扩散;光学偏转器，用于使穿过光投射透镜的光偏转，并用偏转的光照射目标。激光二极管发光，使得光在第一方向上以第一角度扩散，并且在垂直于第一方向的第二方向上以比第一角度宽的第二角度扩散。激光二极管模块被布置成使得其布置方向与第一方向一致，并且它们沿第二方向放置并且在第一方向上相对于彼此移位。光投射透镜设置成对应于激光二极管模块。
主权项	A projection optical system comprising: a laser diode, the laser diode being a light source; a laser diode module having a plurality of the laser diodes arranged in a row; a light projecting lens configured to adjust spread of light emitted from each of the laser diodes; and an optical deflector configured to deflect light passing through the light projecting lens and irradiate a target with the deflected light, wherein the laser diodes emit light such that the light spreads out at a first angle in a first direction and spreads out at a second angle in a second direction, the second angle being wider than the first angle and the second direction being perpendicular to the first direction, wherein a plurality of the laser diode modules is disposed such that an arrangement direction of the laser diodes coincides with the first direction and that the laser diode modules are placed side by side in the second direction and shifted in position relative to each other in the first direction, and wherein a plurality of the light projecting lenses is disposed such that the light projecting lenses correspond to the laser diode modules, respectively.
