LASER LEVELING TOOL WITH IMPROVED LASER PATTERN PROJECTION

A laser leveling tool(1) comprising: a laser source(2) configured to emit a laser beam; and a digital laser beam projection system which transmits the laser beam emitted from the laser source(2) and converts the laser beam into a projection pattern that is to be projected to a target surface; wherein the digital laser beam projection system comprises a pixel panel(6) arranged to receive the laser beam emitted from the laser source(2) and comprising pixel units which are selectively activated to reflect or transmit the laser beam, the reflected or transmitted laser beam conforming to a desired projection pattern to form a patterned laser beam. 一种激光标线仪(1)包括：激光源(2)，其配置成发射激光束；和数字式激光束投影系统，其传输从激光源(2)发射的激光束并将激光束转化成将被投射至目标表面的投影图案；其中数字式激光束投影系统包括像素板(6)，其布置成接收从激光源(2)发射的激光束并且包括像素单元，这些像素单元被选择性地激活以便反射或透射激光束，反射的或透射的激光束与期望的投影图案相符，以形成图案化激光束。
