Frits Zernike was born on July 16, 1888, in Amsterdam, the son of two mathematicians, Carl Frederick August Zernike and Antje Dieperink Zernike.
Zernike published these findings in 1934, and by 1935 he was applying these same principles to microscopes, which he knew had optical problems that were similar to telescopes.
The Zernike polynomials are a method he developed regarding the wave theory of light and are widely used by mathematicians.

 Nikon MicroscopyU: Phase Contrast Microscopy - Introduction
Phase contrast microscopy, first described in 1934 by Dutch physicist Frits Zernike, is a contrast-enhancing optical technique that can be utilized to produce high-contrast images of transparent specimens, such as living cells (usually in culture), microorganisms, thin tissue slices, lithographic patterns, fibers, latex dispersions, glass fragments, and subcellular particles (including nuclei and other organelles).
Zernike's development of phase contrast optical theory is an excellent example of how research results from a highly specialized field (in this case, theoretical physics) can yield innovative new developments in seemingly unrelated disciplines, such as biology and medicine.
Vector representation of wave interactions in phase contrast microscopy was introduced by Frits Zernike, and later developed in detail by Robert Barer.

 Untitled Document
Diffraction theory has been greatly advanced in the 1930-1940's by the joint work of Frits Zernike, the later 1953 Nobel Prize winner because of his invention of the phase-contrast microscope (see photograph), and his PhD-student Bernard Nijboer (thesis submitted in 1942).
Using the famous circle polynomials developed by Zernike, the work of Nijboer has focused on using these polynomials for an efficient representation of the complex field in the exit pupil and in the focal plane.
The collaboration is between a mathematician (Augustus J.E.M. Janssen) and an optics experimentor Peter Dirksen (Bio and Pic), both from Philips Research, and Joseph Braat, teaching optics at Delft University and still active at the Philips Research Laboratories on a part-time basis.

 Olympus Microscopy Resource Center: Specialized Microscopy Techniques - Introduction to Differential Interference ...
Living cells and other transparent, unstained specimens are often difficult to observe under traditional brightfield illumination using the full aperture and resolution of the microscope objective and condenser system.
Phase contrast, first developed by Frits Zernike in the 1930s, is often employed to image these challenging specimens, but the technique suffers from halo artifacts, is restricted to very thin specimen preparations, and cannot take advantage of the full condenser and objective apertures.
The basic differential interference contrast (DIC) system, first devised by Francis Smith in 1955, is a modified polarized light microscope with two Wollaston prisms added, one to the front focal plane of the condenser and a second at the rear focal plane of the objective (see Figure 1).

Optical data processing was inherent in the work of Abbe in 1873 and spatial filtering had its origins in the phase contrast technique invented in 1935 by Frits Zernike.
Although other optical techniques, e.g., shadowgraph and schlieren, could also do this, the phase contrast technique provides a linear relation between phase retardation and image intensity.
Zernike built a microscope based on the principle in 1938 and received the Nobel Prize in 1953.
