Development of a Small Opto-Electronic Distance Measuring Device

摘要

A miniaturized opto-electronic distance measuring device, suitable for mass production and capable of covering a variety of applications, was developed. The principle of time of flight measurement of light pulses is used. The basis of this development is a method of defining the beginning and the end of a time measurement. A prototype meeting the required technical specifications as to distance measuring range, distance, and angle resolution, measuring frequency and averaging, is presented. After running through a preparation phase, it can be produced in large quantities in a relatively inexpensive way. Major application fields will be automation and general distance measurements.
