Abstract

The suitability of a fast, short range time-of-flight distance sensor for industrial applications is considered. Critical characteristics of the sensor are evaluated and compared to those of other type of sensors. Results obtained with a few experimental devices are given. At a range of a few meters the speed of measurement can be up to 2.10⁶ measurements/s with a single pulse resolution of the order of 10 mm. Using averaging the resolution can be improved down to the level of about 100 pm. An example of the design of a fast, short range time-of-flight distance sensor is given. The sensor described is designed to be used at short ranges (<5 m) for passive targets mainly in 3D image acquisition applications. The construction described gives a good concept of the technique needed and its suitability for industrial use.
