Abstract

An intensified solid-state imaging sensor includes a photo cathode for converting light from an image into electrons, an electron multiplying device for receiving electrons from the photo cathode, and a solid-state image sensor including a plurality of pixels for receiving the electrons from the electron multiplying device through a plurality of channels of the electron multiplying device. The solid-state image sensor generates an intensified image signal from the electrons received from the electron multiplying device. The plurality of channels are arranged in a plurality of channel patterns, and the plurality of pixels are arranged in a plurality of pixel patterns. Each of the plurality of channel patterns is mapped to a respective one of the plurality of pixel patterns such that electron signals from each of the plurality of channel patterns is substantially received by the single respective one of the plurality of pixel patterns.

Claims

1. An intensified solid-state imaging sensor comprising:

a photo cathode for converting light from an image into electrons;

an electron multiplying device for receiving electrons from the photo cathode, the electron multiplying device outputting a greater number of electrons than the electron multiplying device receives from the photo cathode; and

a solid-state image sensor including a plurality of pixels for receiving the electrons from the electron multiplying device through a plurality of channels of the electron multiplying device, the solid-state image sensor generating an intensified image signal from the electrons received from the electron multiplying device,

the plurality of channels being arranged in a plurality of channel patterns, and the plurality of pixels being arranged in a plurality of pixel patterns, each of the plurality of channel patterns being mapped to a respective one of the plurality of pixel patterns such that electron signals from each of the plurality of channel patterns is substantially received by the single respective one of the plurality of pixel patterns.

2. The intensified solid-state imaging sensor of claim 1 wherein each of the plurality of channel patterns comprises a single channel, and each of the plurality of pixel patterns comprises a single pixel.
