O1.3 - Sensitive measurement of partial coherence using a pinhole array

Paul Petruck, Rainer Riesenberg & Richard Kowarschik
For applications which require partially coherent light, e.g. in miniaturized interference setups like microimaging systems, the area of spatial coherence should fit to the optical design. For example, we apply partial coherence to lenseless inline holographic microscopy. Even if high coherent sources are suitable for the requirements of interference, a high degree of coherence is responsible for many disturbing effects within the optical system. Especially statistical interferences due to rough surfaces, so called speckles, are...
