Abstract

See full text

A method having the steps of obtaining prepared image data captured by an image sensor receiving light propagated across a sample volume, containing a fluid possibly comprising microscopic objects of foreign origin, while illuminating the sample volume by coherent light. The prepared image data comprising, for a microscopic object, a prepared hologram pattern with prepared spatially alternating intensity formed by the interference fringes; providing filtered image data, comprising automatically filtering the prepared image data by an edge enhancing filter. the filtered image data comprising, for a prepared hologram pattern, a filtered hologram pattern. The presence of the microscopic object associated with the filtered hologram pattern in the sample volume of the fluid is automatically detected on the basis of the filtered hologram pattern.
