Abstract
Imaging apparatus suitable for photon counting applications or low light imaging includes a CCD sensor 4 arranged to receive electrons emitted from a photocathode 1. The CCD sensor includes a separate multiplication register into which signal charge from its output register is transferred to give improved noise performance and resolution.
Claims6
An imaging apparatus comprising a photocathode which emits electrons representative of incident radiation to which it is sensitive, and a CCD sensor which includes an image area, an output register which receives signal charge from the image area, a separate multiplication register into which signal charge from the output register is transferred, and means for obtaining signal charge multiplication by transferring the charge through a sufficiently high field in elements of the multiplication register, the CCD sensor being arranged to receive electrons generated at the photocathode in response to incident radiation.
Imaging apparatus substantially as illustrated in and described with reference to the accompanying drawings.
