Abstract:
In this report are represented the possibilities of the contemporary electronic elements when building optoelectronic measurement devices. In this type of devices the basic components are: a light beam source, photo receiver, managing system for both the light source and the light receiver (this system also processes the received light information and displays it on an indicator). The universal digital managing and processing unit of the devices is based on FPGA. One of its advantages is the possibility to load different processing algorithms for the received information trough JTAG interface with no changes on the schematic of the devices. In this report are described two practical approaches for measurement of distance based on triangulation and measurement of physical dimensions based on laser parallel scanning beam.
