Georges Nomarski
Georges (Jerzy) Nomarski (January 6, 1919 – 1997) was a Polish physicist and optics theoretician. 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. Biography Born in Nowy Targ, Nomarski was educated in Warsaw at the Warsaw University of Technology (known at that time as the ''Warsaw Polytechnic'') and served in the Polish Resistance during World War II. Captured by German forces, he was a prisoner of war until March 1945. After the war when the Soviets supported communists installed their regime over Poland, Nomarski had to escape to Belgium as a political refugee. He studied there briefly before he moved to France for his permanent residence in 1947. He finished his education in France and received his diploma from l'Ecole Supérieure d'Optique Paris (Grande Ecole). In 1950, Nomarski established the ''Laboratoire de Microscopie Optique de L'Inst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differential Interference Contrast
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. DIC works on the principle of interferometry to gain information about the optical path length of the sample, to see otherwise invisible features. A relatively complex optical system produces an image with the object appearing black to white on a grey background. This image is similar to that obtained by phase contrast microscopy but without the bright diffraction halo. The technique was developed by Polish physicist Georges Nomarski in 1952. DIC works by separating a polarized light source into two orthogonally polarized mutually coherent parts which are spatially displaced (sheared) at the sample plane, and recombined before observation. The interference of the two parts at recombination is sensitive to their optical path difference (i.e. the product ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nowy Targ
Nowy Targ (Officially: ''Royal Free city of Nowy Targ'', Yiddish: ''Naymark'', Goral Dialect: ''Miasto'') is a town in southern Poland, in the Lesser Poland Voivodeship. It is located in the Orava-Nowy Targ Basin at the foot of the Gorce Mountains, at the confluence of the Czarny Dunajec and the Biały Dunajec.

Warsaw
Warsaw ( pl, Warszawa, ), officially the Capital City of Warsaw,, abbreviation: ''m.st. Warszawa'' is the capital and largest city of Poland. The metropolis stands on the River Vistula in east-central Poland, and its population is officially estimated at 1.86 million residents within a greater metropolitan area of 3.1 million residents, which makes Warsaw the 7th most-populous city in the European Union. The city area measures and comprises 18 districts, while the metropolitan area covers . Warsaw is an Alpha global city, a major cultural, political and economic hub, and the country's seat of government. Warsaw traces its origins to a small fishing town in Masovia. The city rose to prominence in the late 16th century, when Sigismund III decided to move the Polish capital and his royal court from Kraków. Warsaw served as the de facto capital of the Polish–Lithuanian Commonwealth until 1795, and subsequently as the seat of Napoleon's Duchy of Warsaw. Th ...

Polish Resistance Movement In World War II
The Polish resistance movement in World War II (''Polski ruch oporu w czasie II wojny światowej''), with the Polish Home Army at its forefront, was the largest underground resistance movement in all of occupied Europe, covering both German and Soviet zones of occupation. The Polish resistance is most notable for disrupting German supply lines to the Eastern Front (damaging or destroying 1/8 of all rail transports), providing intelligence reports to the British intelligence agencies (providing 43% of all reports from occupied Europe), and for saving more Jewish lives in the Holocaust than any other Western Allied organization or government. It was a part of the Polish Underground State. Organizations The largest of all Polish resistance organizations was the Armia Krajowa (Home Army, AK), loyal to the Polish government in exile in London. The ''AK'' was formed in 1942 from the Union of Armed Struggle (''Związek Walki Zbrojnej'' or ZWZ, itself created in 1939) and woul ...

Soviets
Soviet people ( rus, сове́тский наро́д, r=sovyétsky naród), or citizens of the USSR ( rus, гра́ждане СССР, grázhdanye SSSR), was an umbrella demonym for the population of the Soviet Union. Nationality policy in the Soviet Union During the history of the Soviet Union, different doctrines and practices on ethnic distinctions within the Soviet population were applied at different times. Minority national cultures were never completely abolished. Instead the Soviet definition of national cultures required them to be "socialist by content and national by form", an approach that was used to promote the official aims and values of the state. The goal was always to cement the nationalities together in a common state structure. In the 1920s and the early 1930s, the policy of national delimitation was used to demarcate separate areas of national culture and the policy of korenizatsiya (indigenisation) was used to promote federalism and strengthen non-Rus ...

Nomarski Prism
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. Like the Wollaston prism, the Nomarski prism consists of two birefringent crystal wedges (e.g. quartz or calcite) cemented together at the hypotenuse (e.g. with Canada balsam). One of the wedges is identical to a conventional Wollaston wedge and has the optical axis oriented parallel to the surface of the prism. The second wedge of the prism is modified by cutting the crystal so that the optical axis is oriented obliquely with respect to the flat surface of the prism. The Nomarski modification causes the light rays to come to a focal point outside the body of the prism, and allows greater flexibility so that when setting up the microscope A microscope () is a laboratory instrument used to examine objects that are too small to be seen by the naked eye.
