Abstract

The imaging apparatus detects the presence in a field of view of an emitter of electromagnetic radiation of characteristic wavelength and comprises a semiconductor charge transfer device which is sensitive to the radiation and is capable of providing a useful output. The apparatus further comprises a radioactive decay source of radiation of a wavelength to which the charge transfer device is sensitive, to illuminate the semiconductor device. Preferably the source is such that radiation from the source incident upon the charge transfer device biases it to at least primed zero however low is the intensity incident on the charge transfer device of the background radiation. Preferably the apparatus includes a narrow band optical filter which attenuates strongly all wavelengths except those within a narrow band comprising the characteristic wavelength.
