Abstract

Active, laser based 3-D sensing techniques can provide several practical advantages for direct, real time depth measurement. Numerous active techniques exist ranging from camera based structured light used for object detection and height measurement through scanning laser radar systems targeted for complex tasks like robot navigation. In all systems the performance is limited by the level of optical and electronic noise in the system. This paper identifies the fundamental sources of optical and electronic noise and presents data which can be used to estimate the performance of several system configurations. The data is generally useful for improving the signal detection capability of many types of imaging systems. Implementation of noise reduction techniques can provide extraordinary optical and electronic dynamic range, particularly when laser scanning 3-D imaging systems are used.
