Title: **Hendrik Tjalling Dijkstra: Innovator in Optical Technology**
Introduction
Hendrik Tjalling Dijkstra, an accomplished inventor based in Eindhoven, Netherlands, has made significant contributions to the field of optical technology. With a remarkable portfolio of 12 patents, Dijkstra has been at the forefront of innovation, particularly in methods for detecting blood cells and platelets in fluid samples.
Latest Patents
One of Dijkstra's latest patents is the **Optical Platelet Counter Method**. This groundbreaking invention involves detecting platelets or blood cells in a fluid sample by adjusting the focal depth of a microscope. The microscope is equipped with a mounted sample and an objective lens that can be optimized using either a spherical aberration correction unmatched to the utilized cover plate or a numerical aperture that is not matched to the illumination source for the sample. The method records images at various specific focal depths and across multiple z planes in a fluid containing the platelets. This process generates a distinctive light-dark pattern, indicative of the platelets at particular positions and depths in the fluid media, enabling accurate analysis of these vital components.
Career Highlights
Throughout his impressive career, Dijkstra has worked with notable companies such as U.S. Philips Corporation and Koninklijke Philips Corporation N.V. His experiences within these organizations have greatly influenced his innovative capabilities and contributed to his success as an inventor.
