    摘要: An imaging device captures both a visible light image and a diagnostic image, the diagnostic image corresponding to emissions from an imaging medium within the object. The visible light image (which may be color or grayscale) and the diagnostic image may be superimposed to display regions of diagnostic significance within a visible light image. A number of imaging media may be used according to an intended application for the imaging device, and an imaging medium may have wavelengths above, below, or within the visible light spectrum. The devices described herein may be advantageously packaged within a single integrated device or other solid state device, and/or employed in an integrated, single-camera medical imaging system, as well as many non-medical imaging systems that would benefit from simultaneous capture of visible-light wavelength images along with images at other wavelengths.

    摘要: A semiconductor opto device is disclosed. One embodiment provides an optodiode. The optodiode has a relative spectral sensitivity that is adapted to the relative spectral sensitivity of an eye, wherein, correspondingly adapted to the spectral sensitivity of the eye, a switch-on or switch-off process of the optothyristor or optotriac is triggered.

    摘要: An improved THz detection mechanism includes a heterojunction thyristor structure logically formed by an n-type quantum-well-base bipolar transistor and p-type quantum-wellbase bipolar transistor arranged vertically to share a common collector region. Antenna elements, which are adapted to receive electromagnetic radiation in a desired portion of the THz region, are electrically coupled (or integrally formed with) the p-channel injector electrodes of the heterojunction thyristor device such the that antenna elements are electrically connected to the p-type modulation doped quantum well interface of the device. THz radiation supplied by the antenna elements to the p-type quantum well interface increases electron temperature of a two-dimensional electron gas at the p-type modulation doped quantum well interface thereby producing a current resulting from thermionic emission over a potential barrier provided by said first-type modulation doped quantum well interface. This current flows over the p-type channel barrier to the ntype quantum well interface, thereby causing charge to accumulate in the n-type quantum well interface. The accumulated charge in the n-type quantum well interface is related to the intensity of the received THz radiation. The heterojunction-thyristor-based THz detector is suitable for many applications, including data communication applications and imaging applications.

A first enclosing one of the semiconductor regions containing all other ones of the semiconductor regions is of the second conductivity type. A plurality of reset switches each has a first terminal coupled to a different one of the alternating semiconductor regions, and a second terminal switchably coupled to a reset potential. Each one of a plurality of storage nodes is coupled to a separate one of the plurality of alternating semiconductor regions.

    摘要: Large current gains and high degrees of sensitivity to impinging primary photons are realized in photon feedback photodetectors embodying the invention. A photocurrent generated by an internal photodiode (10, 11) in response to the primary photons (6) causes secondary photons to be emitted by internal serially connected luminescence diodes (12, 13; 14, 15). Secondary photons traveling away from the photodiode are redirected by a reflector (16) to impinge on the photodiode and thereby sustain the photocurrent. Gains of the order of 100 are realized by these photodetectors.

    摘要: A phototransistor is operated with a floating base but with the transistor operating point defined by prebiasing the base, typically by injecting the base current through a prebias emitter in the collector region outside of the depletion layer. The phototransistor has a signal to noise ratio comparable to those of optimized avalanche photodiodes but operates at a significantly lower voltage and without need for temperature compensation. The phototransistor is especially well-suited for optical communications at high data rates.
