Ernst Abbe and the Foundation of Scientific Microscopes

Last year marked the 100th anniversary of the death of Ernst Abbe, who passed away on January 14, 1906—just a few days short of his 65th birthday. In addition to his groundbreaking optical work, which includes his diffraction theory for image formation and the formulation of the sine condition and Abbe number, he was also a noted entrepreneur, astronomer and social reformer.

Welcome to the Wonderful World of 3D: Anaglyph Experiments. Third article of a four-part series.

The first two installments in this four-part series explored the history and principles of 3D imaging and provided instructions for creating 3D images. This article is devoted to anaglyph experiments, which use complementary colors to create 3D illusions.

Intrinsic Coherence: A New Concept in Polarization and Coherence Theory

The concept of interference has always been critical to our grasp of the nature of the light—from the time of Christiaan Huygens and Isaac Newton to the groundbreaking work of Emil Wolf and Roy Glauber on coherence theory. Building on the latter contributions, these authors analyze intrinsic coherence properties of partially polarized light.

The History of OSA

Reminiscences

In 1973, OSA president-elect Dow Smith wrote to several previous OSA presidents and medalists, asking them to recount memories from OSA meetings. This article captures the responses of past presidents George Harrison (1945-1946) and Stanley Ballard (1963), and the 1973 C.E.K. Mees medalist Erik Ingelstam.

Microstructure Technique “Blackens” Metals

A new laserablation technique alters the surfaces of metals such as platinum and tungsten, so that the metals absorb nearly 100 percent of the light that falls on them.
