摘要

Laser triangulation displacement sensor using the single point laser or linear laser as the source is widely used in industry. The sensor uses the triangulation principle among light source, tested object and receiver with high speed and non-contact advantages. However, the structure of most of traditional laser triangulation sensors is split that an external amplifier controller is necessary, causing a complicated system. An integrated structure of laser triangulation displacement sensor is put forward in this paper. All signal collection and processing systems are integrated in the probe so that the sensor can be convenient to measure. The limited volume of sensor leads to the change of layout. So the image quality of spots also changes as well. The layout and the principle of the sensor are introduced. The expression of the light spot is also analyzed. A new measurement method of spot processing is also proposed at the same time. Some experimental results are also given to show the efficiency of the new algorithm.
