Paper Abstract

Reports a laser diode alignment system for monitoring dam, building, bridge, etc. It comprises a light source and a receiving unit. The former is mainly composed of a laser diode for emitting light in red spectrum band at wavelength of 680nm, a single mode fiber for spot transforming and mode selecting, and a reverse telescope for collimating the emission light beam. The whole light source is mounted on a 4-dimension adjustable table fixed on a tripod. The latter is an embedded computer based on PC104 architecture. It contains a mainboard, an image grabber, a LCD display and a CCD. Central position of the light spot is calculated according to barycenter method. It is proved by experiments in lab that within a span of 8m the direction stability of the alignment system is up to 1X10-6 magnitude order.
