Abstract: [0040] An advanced image intensifier assembly provides enhanced functionality. A grounded photocathode provides shielding from electromagnetic interference, improving the ability to work in multiple light conditions. Bi-directional wireless communication and non-volatile storage allow critical information to be permanently stored and read wirelessly at a scanning station, easing in identification of units. Because bi-directional communication components can be embedded within an image intensifier assembly, existing end-user night vision devices can be upgraded by simply replacing the image intensifier assembly. For enhanced safety, a programmable shutdown capability is provided. This renders the device inoperative in the absence of continuous input, either wireless or manual, from an authorized operator, thus rendering the device useless if captured by enemy combatants. Finally, direct 1- volt operation enables the device to be powered by, for example, a single AA battery.

Abstract: The invention provides a switchable photomultiplier switchable between a detecting state and a non-detecting state comprising a cathode upon which incident radiation is arranged to impinge. The photomultiplier also comprises a series of dynodes arranged to amplify a current created at the cathode upon detection of photoradiation. A first dynode of the series is operatively closest to the cathode and is at a first potential and the electrical potential of the cathode is switchable between a second potential, below the first potential, when the photomultiplier is in the detecting state and a third potential, above the second potential, when the photomultiplier is in the non-detecting state. The invention also provides a detection system arranged to detect radiation-emitting material in an object. The system comprises a detector switchable between a detecting state in which the detector is arranged to detect radiation and a non-detecting state in which the detector is arranged to not detect radiation. The system further comprises a controller arranged to control switching of the detector between the states such that the detector is switched to the non-detecting state whilst an external radiation source is irradiating the object.

Abstract: A photocathode in which the photocathode plate can be securely fixed without using any adhesive. Even under the severe condition that a high vibration resistance is required or thermal stress occurs because of great temperature variation, it can be used widely for an image intensifier, a streak tube, or a photomultiplier. The photocathode plate (16) of the photocathode (10) is sandwiched between a faceplate (11) and a support plate (19). First pins (12, 13) buried in the faceplate (11) are joined to the support plate (19). Therefore the photocathode plate (16) can be readily fixed securely to the faceplate (11) without using any adhesive. An electron tube is also disclosed.

Abstract: PROBLEM TO BE SOLVED: To provide a photocathode plate capable of obtaining highly sensitive characteristics stably, and to provide an electron tube using such a photocathode plate. SOLUTION: In a photomultiplier tube 1, an insulating layer 63 is formed between a semiconductor electron-discharging layer 51 in the photocathode plate 23A and a first electrode 65 electrically connected to an electron emission section 59. The insulating layer 63 can perform heat cleaning to the photocathode plate 23A at a high temperature in a stage before an active layer 61 is formed at an exposed portion in the semiconductor electron-discharging layer 51 at the electron emission section 59, thus effectively cleaning the exposed portion in the semiconductor electron-discharging layer 51 at the electron emission section 59, stabilizing physical properties at the exposed portion, and hence stably obtaining the highly sensitive characteristics in the photocathode plate 23A and the photomultiplier tube 1 using the photocathode plate 23A.
