Latest Patents

Esa Hamalainen's latest patents include a method for detecting microscopic objects in fluids by optical sensing. This method involves obtaining prepared image data captured by an image sensor that receives light propagated across a sample volume containing a fluid, which may include microscopic objects of foreign origin. The process utilizes coherent light to illuminate the sample volume, resulting in prepared hologram patterns formed by interference fringes. The presence of microscopic objects is detected based on filtered hologram patterns derived from the prepared image data.

Another significant patent is a measuring arrangement for in-line holography microscopy. This arrangement features an illuminating setup that emits coherent light and a cuvette designed to hold a fluid potentially containing microscopic objects. The cuvette allows coherent light to enter and exit through designated openings, with an image sensor capturing hologram digital images of the light propagated across the cuvette. This innovative approach enhances the detection and analysis of microscopic objects in various fluids.
