Abstract: An image sensor array has overlapping responsive zones, for detecting incident radiation. The sensor array includes a plurality of collection electrodes for sensing charge and a charge distribution layer in contact with the collection electrodes. The charge distribution layer is configured to distribute charge generated from incident radiation to more than one collection electrode, effectively providing overlapping responsive zones that reduce adverse aliasing effects.

Abstract: A thin-film, flat panel, pixelated detector array serving as a real-time digital imager and dosimeter for diagnostic or megavoltage X rays or gamma rays, including a plurality of photodiodes (30) made of hydrogenated amorphous silicon arrayed in columns and rows upon a glass substrate (12). Each photodiode (30) is connected to a thin film field effect transistor (52) also located upon the glass or quartz substrate (12). Upper and lower metal contacts (38, 22) are located below and above the photodiodes (30) to provide the photodiodes (30) with a reverse bias. The capacitance of each photodiode (30) when multiplied by the resistance of the field effect transistor (52) to which it is connected yields an RC time constant sufficiently small to allow fluoroscopic or radiographic imaging in real time.

Abstract: A solid state radiation sensor array panel (10) comprising a thick deposited radiation detector layer (16) capable of generating electron-hole pairs in response to being irradiated, and a matrix array of transistors comprising source and drain electrode elements, a charge-transport layer (22), and a dielectric layer (34) disposed over one surface of the detector layer. Means are provided for establishing an electric field across the detector layer, which field is collapsible to establish a higher field in irradiated areas so as to establish a current path, between the source and drain electrode elements, through pixel areas of the charge-transport layer. The currents passing through pixel areas are passed to a readout circuit for processing the radiation image information.

Abstract: An image-sensing apparatus (10) of the type employing resolving and sensing means is provided with sensors (30) of selected size and geometry to allow approximation of desired response. The sensors may be incorporated into compact, self-contained image-resolving and-sensing apparatus having a transparent substrate (12) for resolving an incident image by refraction, diffraction or other suitable mechanism. The sensors may be located directly on a surface (14) of the substrate. Logic and select circuitry (20) may be integrally and simultaneously formed with the sensors. The size and geometry of the sensors may enable approximation to color inhibition and other effects to allow approximation to the spectral response of the human eye.

Abstract: A compact, self contained image resolving and sensing apparatus of the type used in electronic imaging applications includes a plurality of sensing devices (30) such as photodetectors formed on a transparent substrate (12) capable of resolving a polychromatic image incident thereupon. The mechanism by which the substrate resolves the incident image may be refraction, diffraction or other suitable mechanism. The sensing devices are sized and located on the substrate such that they are capable of detecting one or more wavelength components of the resolved polychromatic image. Logic and select circuitry may be formed on the substrate generally contemporaneously and of similar materials as the sensing device. In one embodiment, the sensing devices (30) are located on a primary surface (14) of the substrate, and polychromatic light is incident on a bevelled adjacent surface (16). The light is refracted, with different wavelength components being detected by different sensing devices (30). The incident light may be reflected from a document (50) and focussed onto the sensing apparatus by a lens (52).
