   Phase contrast is a microscopy technique that improves a contrast of unstained biological specimens. It allows for visualizing differences in light phase caused by passing different parts of the specimens, otherwise invisible to human's eye. This technique was developed in 1930's by Frits Zernike, who was awarded a Nobel Prize in 1953.
