Mieczysław Wolfke

From Wikipedia, the free encyclopedia

Mieczysław Wolfke (1883 – 1947) was a Polish physicist.

Wolfke is known for his discovery of two types of liquid helium, of which He II is still the only known superfluid liquid. He did ground-breaking work in holography, an area of optics dealing with the creation and recording of three-dimensional images: in 1920 he divided the process of creating such images into two distinct phases by using two beams of light, each having a different wavelength.

Dennis Gabor, the 1971 Nobel laureate in physics, named Mieczysław Wolfke as one of his precursors in the development of holography.
