Differential interference contrast (DIC) microscopy, also known as Nomarski interference contrast (NIC) or Nomarski microscopy, is an optical microscopy technique used to enhance the contrast in unstained, transparent samples.
Georges (Jerzy) Nomarski (January 6, 1919 – 1997) was a Polish physicist and optics theoretician. He was the creator of differential interference contrast (DIC) microscopy. The method is widely used to study live biological specimens and unstained tissues and in many languages bears his name.
A Nomarski prism is a modification of the Wollaston prism that is used in differential interference contrast microscopy. It is named after its inventor, Polish and naturalized-French physicist Georges Nomarski .
The success of the phase-contrast microscope has led to a number of subsequent phase-imaging methods. In 1952, Georges Nomarski patented what is today known as differential interference contrast (DIC) microscopy. [8] It enhances contrast by creating artificial shadows, as if the object is illuminated from the side.
A congressman is pushing for a law change that would allow President Trump to run for a third term -- but would prevent other living presidents from returning to the White House.
1955: Georges Nomarski, professor of microscopy, published the theoretical basis of differential interference contrast microscopy. [ 14 ] 1957: Marvin Minsky , a professor at MIT , invents the confocal microscope , an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to ...
