用普通水准仪对房屋从顶到底进行大面积的测量并确定水平面时,非常困难,因此,美国俄亥俄州的一家精密仪器公司,开发出一种利用激光光束的水准仪,命名为“激光精测仪”。使用时,将激光光束对准测定方位,激光光束能在75米和35米之间的距离内完成精确测定,而且精度极高。另外,激光器还能咬住垂直度和45度的倾角跟踪测量。对于那些难度大的测点,该仪器还能在底部附加一只带V字形 Therefore, a precision instrument company in Ohio, USA, has developed a level meter that uses a laser beam and names it as a “laser sounder ”. When used, the laser beam is directed at the measuring position, the laser beam can be accurately measured within a distance of 75 meters and 35 meters, and the accuracy is very high. In addition, the laser can bite verticality and 45 degrees of tilt tracking measurements. For those difficult measuring points, the instrument can also be attached to the bottom of a V-shaped
