Infrared 100 years on

摘要

The year 2010 is significant in the infrared timeline. It marks the centenary of the first published infrared photograph by Professor Robert Williams Wood. Indeed, modern-day thermal imaging and thermography owe much to this American physicist's groundbreaking work in optics and spectroscopy. In October 1910, Professor Williams Wood gave a presentation to the Royal Photographic Society entitled: 'Photography by Invisible Rays'. To commemorate this event, an Infrared Symposium was held 7-8 October 2010 at the Royal Astronomical Society in London.
