CCD camera having an anti-stokes phosphor bound thereto

摘要

A camera includes a charge-coupled device (CCD). The CCD has an anti-stokes phosphor bound to the light receiving surface of the CCD. The anti-stokes phosphor emits electromagnetic radiation having wavelengths in the range of 950 nm to 1100 nm. A housing surrounds the CCD and defines a filtered aperture through which, in use, light can pass and be received by the phosphor CCD.
