Paper, 'Preliminary note on the "radio-micrometer" a new instrument for measuring the most feeble radiation' by C V [Charles Vernon] Boys

Reference number: PP/10/24

Date: 1887

Description

Boys writes: 'Till lately the thermopile and galvanometer have afforded the most delicate means of detecting and measuring radiant energy. This combination has been surpassed by Professor Langley, who has made use of the increased resistance of metallic wires or the diminished resistance of a carbon filament when warmed. It seems difficult to believe, in consequence of the very small change of resistance which even iron undergoes when slightly warmed, that this is the best principle to make use of in designing the most sensitive possible instrument.'
