PROBLEM TO BE SOLVED: To provide a laser scanner having high reliability.SOLUTION: The laser scanner includes a light source 11 emitting laser light, a liquid crystal element for partially transmitting the laser light emitted from the light source 11, an optical element 13 for deflecting the laser light transmitted through the liquid crystal element, and a light-receiving element for detecting the laser light reflected by an object. The liquid crystal element has a plurality of regions each of which can be set into one of a transmitting state and a light-shielding state, and transmits laser light in the laser light emitted from the light source, incident to at least one of the plurality of regions.SELECTED DRAWING: Figure 6 【課題】信頼性の高いレーザ走査装置を提供する。【解決手段】レーザ走査装置は、レーザ光を発光する光源１１と、光源１１から出射されたレーザ光を部分的に透過させる液晶素子と、液晶素子を透過したレーザ光を屈折させる光学素子１３と、対象物によって反射されたレーザ光を検知する受光素子とを含む。前記液晶素子は、透過状態及び遮光状態の一つにそれぞれが設定可能な複数の領域を有し、前記光源から出射されたレーザ光のうち前記複数の領域の少なくとも1つに入射するレーザ光を透過させる。【選択図】図６
