A bolometer (Greek: βολόμετρον `bolometron`, meaning measurer (-μετρον) of thrown things (βολο-) ) is a device for measuring the power of incident electromagnetic radiation via the heating of a material with a temperature-dependent electrical resistance. It was invented in 1878 by the American astronomer Samuel Pierpont Langl.....
