Abstract
The disclosed charge transfer signal processor includes a vacuum housing having an input face and an output face, a 2-D electromagnetic input means cooperative with said input face for providing a 2-D input electronic charge signal within the vacuum housing, transfer means for imaging the 2-D input electronic charge signal in a region of the vacuum housing proximate the vacuum housing output face, and charge feedthrough means coupled to the vacuum housing output face for transferring the imaged 2-D electronic charge signal externally to the vacuum housing. In one embodiment, the charge transfer signal processor is operable as Gen-1 charge transfer amplifier. In another embodiment, a microchannel plate assembly is disposed in the vacuum housing intermediate the input and output faces, and the charge transfer signal processor is operable as a high-gain charge transfer signal amplifier. In a futher embodiment, a power microchannel plate assembly is disclosed that is disposed in the vacuum housing intermediate the input and output faces, and the charge transfer signal processor is operable as a high-current charge transfer signal amplifier. The disclosed power microchannel plate assembly preferably includes a 2-D array of axially-aligned discrete dynodes, and a voltage divider network operatively coupled to the 2-D array for providing an electron accelerating potential gradient and for replacing charge as it is depleted by secondary electron emission processes in the several discrete dynodes. The 2-D input electromagnetic signal may either be optical, electronic, or a combination of these two. Various output devices externally mounted to the output face of the vacuum housing are disclosed. Utility includes spatial phase and/or amplitude light modulation, 2-D optical signal processing, and, among others, electromagntic signal detection. A method and an apparatus are disclosed for fabricating the charge feedthrough means.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
