17 apr 2024 · Frits Zernike was a Dutch physicist, winner of the Nobel Prize for Physics in 1953 for his invention of the phase-contrast microscope, an instrument that permits the study of internal cell structure without the need to stain and thus kill the cells. Zernike obtained a doctorate from the University.

22 apr 2024 · "Frits Zernike" published on by null. (1888–1966) Dutch physicistZernike, who was the son of mathematics teachers at Amsterdam in the Netherlands, studied at the university there, obtaining a doctorate in 1915.
10 apr 2024 · Zernike polynomials are a sequence of orthogonal polynomials that play a crucial role in optics and in particular in modeling microscopy systems. First introduced by Frits Zernike in 1934, they are particularly useful in expressing wavefront aberrations and thus imperfections of imaging systems.
12 apr 2024 · The Zernike wavefront sensor (ZWFS) uses the phase-contrast technique, first developed for microscopy, and for which Frits Zernike was awarded the Nobel Prize in 1953. This technique consists of converting phase aberrations into intensity variations that can be measured with a detector.
1 giorno fa · In order to account for correlation in the positions of particles the direct correlation function was introduced as the effective interaction between two particles in the presence of a number of surrounding particles by Leonard Ornstein and Frits Zernike in 1914.
16 apr 2024 · In 1934, Frits Zernike, a Dutch physicist, described it for the first time. Principle. Light is affected by phase shifts when passing through cells, but these changes cannot be seen by the human eye. Phase-contrast microscopes can detect these phase shifts by noticing changes in image contrast caused by changes in amplitude. Working.
