    Abstract: A hybrid photon detector with a photocathode in reflective mode where the same vacuum tube components acts both as a perfect incoming light concentrator and as a perfect focusing electron lens and the photoelectrons are electrostatically focused by the same CPC-shape in the opposite direction (i.e., from the small light collection surface towards a point-like region in the middle of the large-area entrance aperture). The CPC is electrically conductive and split into two electrodes by a narrow nonconductive interval positioned in a particular place along the CPC. The photocathode covers the light collection area of the CPC, and the photocathode is operated in the reflective mode such that photoelectrons emerge from the same surface through which the photons enter. Photoelectrons emerging from the entire photocathode are accelerated and focused onto a small electronic sensor placed in the middle of the entrance aperture of the CPC.

    Abstract: An imaging camera includes a housing that defines a proximal end and a distal end. A Fresnel lens is installed in the proximal end of the housing. Moreover, a reflection mode photocathode is installed in the distal end of the housing opposite the Fresnel lens. An electron sensor is disposed in the center of the Fresnel lens. A conductive layer is disposed on the interior of the housing. Further, the Fresnel lens establishes plural concentric optically passive surfaces that are parallel to a central axis defined by the imaging camera. A conductive layer is disposed on each optically passive surface, and an electron lens is established by the conductive layer on the interior of the housing and the conductive layers on the Fresnel lens.
