SYSTEM-LEVEL ANALYSIS AND OPTIMIZATION OF TASK-ORIENTED IMAGING SYSTEMS

The design of an electro-optical system such as a vision system is classically made by optimizing its constituting parts independently. However, because of the complexity of the overall system, the best performance of a single element may not correspond to that of the complete processing chain. In this paper a tool named SLALOM, acronym of “System Level AnaLysis and OptiMization” is proposed. SLALOM is a C-based extension to optical design software that includes the modeling of the electronic subsystem not encompassed by the software itself. It consists in two complementary tools that share a common core and can be executed independently to perform lens design at system level, and to simulate the overall system performance.
