摘要： An x-ray imaging system includes an x-ray source for providing x-ray photons which are directed towards a subject and impinge on a scintillating screen. The scintillating screen converts the x-ray photons into a visible light image. The screen is formed of discrete, elongate fiber optic elements arranged side-by-side, having a mirrored surface at one end thereof. The elements are formed of a mixture of glass and rate earth elements which convert the x-ray photons into visible light by first phosphoring and then lasing. The system includes a camera system for capturing the visible light image for remote viewing. A method of constructing the scintillating screen of the invention is disclosed.

摘要： In a streak tube wherein a photocathode and an acceleration electrode are disposed in confronting relation to each other for accelerating a photoelectron beam emitted from the photocathode, at least one of the photocathode and the acceleration electrode is formed on a strip-like electrode. A pulse voltage is applied to the strip-like electrode, whereby a very intensive pulsed electric field is developed between the photocathode and the acceleration electrode with the application of a relatively low pulse voltage. Interactive regions of the photocathode and the acceleration electrode are closely position with high accuracy. The streak tube can thus generate a streaked image with a very high time resolution without an increase in the background emission on a phosphor screen.

摘要： An optically functional device has a semiconductor substrate, a light receiving portion disposed on the semiconductor substrate for receiving input light, a light emitting portion disposed on the light receiving portion for emitting output light, a window disposed above the light emitting portion, through which input light and output light pass and a resistance layer made of a semiconductor for functioning as load resistance. The resistance layer is disposed at least in either place between the semiconductor substrate and the light receiving portion, or between the light receiving portion and the light emitting portion, or on the light emitting portion. The light emitting portion has a light emitting layer made of semiconductor material having an energy of forbidden band width of more than the energy of a main peak of input light. The light receiving portion has a base and a collector each of which is made of a semiconductor material having an energy of forbidden band width equal to or less than the energy of a main peak of input light. The light emitting portion is adapted to feed back a part of the output light to the light receiving portion. Thereby a nonlinear output response to input light is performed based on the feedback effect of the output light absorbed by the light receiving portion.

摘要： An integrated LIDAR receiver includes a single detection element to provide both imaging and ranging functions. The single detection element includes an opaque photocathode, a microchannel plate (MCP) electron multiplier, and a phosphor coated anode covered with a metalized layer. The metalized layer on the phosphor anode allows electrons striking the anode to be detected as a prompt electrical current and used as a first output signal to provide ranging information. Visible light (photons) is also output from the anode in response to electrons striking the phosphor in the anode, and is used to provide an intensified image of a scene. The visible light may thereafter be detected by an imaging sensor, such as a CCD camera. The phosphor anode is biased at ground potential. A transimpedance amplifier is coupled to the metalized layer on the phosphor anode and, with the anode being at ground potential, operates with a virtual null input.

摘要： A wafer of neutron transmutation doped silicon having a p-n junction between extended opposite surfaces is formed with bevelled edges. A single or plurality of reverse biased signal contacts is disposed on one surface to provide a single or integrated array of avalanche photodiodes. In addition, an avalanche photodetector (APD) capable of detecting a single photoelectron or imaging multiple photoelectrons comprises a light sensitive photocathode, similar to that in a photomultiplier tube, acting as a converter to produce photoelectrons, which are then accelerated to an anode. The anode comprises a single avalanche photodiode (AP) for detecting or an array (APA) for imaging photoelectrons. The energetic photoelectrons striking the AP or the APA serve as the AP or APA's input signal, respectively.

摘要： Electrons emitted from a photocathode in response to incident X-rays are accelerated and focused onto a microchannel plate (MCP). The electrons multiplied by the MCP are converted into a visible light image by a phosphor screen. An envelope tube is curved at a halfway portion, and the electrons are deflected by a deflection coil so as to travel along the curved envelope tube and enter the MCP. Even if X-rays are transmitted from the photocathode, they do not enter the MCP directly and hardly contribute to the background noise. A limiting aperture ring may further be employed to prevent the X-rays reflected by the inside wall of the envelope tube from entering the MCP.

摘要： An electron tube, such as a streak tube, is equipped with a gate element for gating unnecessary photoelectrons to prevent them from appearing as a pseudo output signal. A deflection voltage of main deflection plates (typically travelling-wave type) is delayed by a predetermined time and provided to the gate element. The gate element may be shifting deflection plates for sweeping the photoelectrons in a direction perpendicular to the main sweeping direction, a microchannel plate for multiplying the photoelectrons, or a photocathode.
