7 April 1998 Sensing applications of diffractive optics with broadband illumination
Author Affiliations +
The flexibility of diffractive optics can offer interesting solutions to a variety of sensing problems. Here, we consider two examples: (1) the determination of the color of LEDs and (2) correlation spectroscopy. In both cases, optical setups are matched to a specific task which results in efficient and impulse systems. This makes them interesting for sensing applications in process control and monitoring. Compact micro-optical systems result by using lithographic fabrication and integration of the free-space optical components on single substrates. We describe principles and basic applications of our concept.
