Abstract
The invention provides a laser receiver with an adjustable reception precision. The laser receiver is a three-stage laser receiver. Among the three sets of laser detectors of the laser receiver, the two sets which are arranged in parallel can move relatively. Along a laser source direction, an upper set of laser detector can shield a lower set of laser detector, such that the laser receiving range of the shielded set of laser detector can be changed, and the precision of the laser receiver is changed. Therefore, the laser receiver provided by the invention can be used in high-precision application occasions, such as indoor decoration with a millimeter-grade precision requirement, and can also be used in low-precision application occasions, such as agricultural flattened lands.
