Optimization of Free-Form Illumination Optics

Abstract:

We have developed optimization methods for generating free-form surfaces. The main applications are in the industrial on-line spectroscopic and machine visions measurements, where spectral and spatial uniformity, good efficiency and pass-line stability are required parameters. We used commercial software for ray-tracing engine. We have developed in-house optimization routines, but used also build-in functions. In this work we have designed a speckle free alternative for laser line generation based on the LED sources. The optical system is based on the collimation part and a free-form mirror. Simulation results are presented.
