Abstract
A sensor and method for taking range measurements of a target object using a TDI device as a detector 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 TDI 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 TDI 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.
