1. A vehicle-mountable system for detecting a characteristic of an object, the system comprising:
- a radiation source adapted to generate a simultaneously pulsed radiation pattern;
at least one detector having a plurality of pixels;
a processor adapted to process data from the at least one detector when radiation from the radiation source is reflected by an obj ect and detected by the at least one detector;
a synchronization means interfacing between the at least one detector and the radiation source;
wherein the synchronization means is adapted for synchronizing the at least one detector with the radiation source so that detection by the detector of radiation to be processed is detected only during the radiation pulses,wherein the radiation source comprises at least one laser adapted for generating a plurality of laser spots constituting said pulsed radiation pattern,wherein the processor is adapted for determining a characteristic of the object by determining a displacement of detected spots detected with the at least one detector with reference to predetermined reference spot positions,and wherein said determining of said displacement is performed with sub-pixel accuracy by multipixel fitting said detected spots.

Abstract
A system for detecting the profile of an object. The system having a radiation source for generating a radiation pattern. The system also having a detector which has a plurality of pixels and a processor for processing data from the detector when radiation from the radiation source is reflected by an object and detected by the detector. The system also has a synchronization device for interfacing between the detector and the radiation source. The radiation source is designed for operating in pulsed mode and the synchronization device can synchronize the pulses of the radiation source with the sampling of the detector.
