Paper Abstract

This article presents the results of an analysis and a discussion of the signal processing requirements for a video rate laser range finder. The lateral effect photodiode is chosen as the position detector for its speed, ease of use, and cost trade-offs over other sensors. Two models are presented for this sensor: the transmission line and the lumped elements. Both are investigated for possible use in circuit analysis. The latter model is selected, although it is not as accurate as the first one. However, it can yield valuable results able to show dependences between system parameters. The results of a linear circuit analysis give some trade-offs for optimum current to voltage conversion for fast response lateral effect photodiodes. Also, a discussion of the merits of techniques for position calculation, to increase the dynamic range of the system and reduce both costs and circuit complexity, is presented.
