SENSOR AND METHOD FOR RANGE MEASUREMENTS USING A TDI DEVICE

摘要

A sensor and method for taking range measurements of a target object using a TDl device as a deflector are provided. The device is positioned to detect reflections of a structured light beam on the target object. To avoid losing the range information in the TDl process, the exposition of the device to the reflection of the light beam is restricted to the first integration period of the acquisition cycle of the TDl device, so that the output of the device provides line by line an image of the light beam on the target object during this first integration period.
