Device and method for recording and evaluating microscopic and / or speckle images of samples or surfaces of a sample plane with a Auflichtaufbau and their use

摘要

The invention relates to a device for recording microscopic images and/or speckle images of samples or surfaces of a sample plane and the use thereof. Here, an epi-illumination design, in which coherent light is directed perpendicularly onto a sample plane from a punctiform illumination source, is present. Light reflected by the sample plane and/or a sample arranged on the sample plane is directed to an effective surface of a detector array, which is aligned parallel to the sample plane, without an imaging optical element arranged therebetween in the beam path. Here, the detector array is connected to a data processing unit, in which there is a calculation of microscopic images and/or speckle images, which were registered at time intervals M and/or after the occurrence of at least one event, and further variables derivable therefrom.
