However, these systems were simply methods of illumination with the obvious, and sometimes very dangerous drawback, that everyone could see the source of the light. For this reason it became vital that a solution be found for military use - a decisive advantage was to be achieved by gaining the ability to see at night without being seen. In 1887, Heinrich Hertz first discovered photoemission, on which night vision technology is based. In 1905, no lesser person than Albert Einstein theoretically explained the principle - the release of electrons from a solid material due to energy put in to it from radiation and light. The breakthrough came about in 1936 when the first Active Infrared system was developed using a silver photocathode. These systems were very bulky and primitive by todays standards, but at the time they represented a major military advantage. Active Infrared systems continued in use until the late 1970’s in some countries, but NATO forces were phasing them out by the late 1960’s. The main drawback of Active Infrared systems was that to operate they required powerful infrared lamps, which meant the range was restricted by the performance of the lamp.

    A Guide To Canada’s Export Control List December 2018 Introduction INTRODUCTION The issuance of export permits under the Export and Import Permits Act (EIPA) is administered by the Trade and Export Controls Bureau of Global Affairs Canada. To assist exporters, the Trade and Export Controls Bureau publishes on its website (www.exportcontrols.gc.ca) important information, such as the Export Controls Handbook, Export Controls Online (EXCOL), Notices to Exporters, Frequently Asked Questions (FAQs), Commodity Codes, and the contact information for the divisions in the Trade and Export Controls Bureau administering export controls for specific items. For information on how to apply for an export permit and additional information on export controls, please refer to our website: www.exportcontrols.gc.ca. For detailed information on export controls, please refer to the Export Controls Handbook: The main reference tool to assist exporters with questions about the administration of Canada’s export controls (except export of logs). The handbook includes how to obtain the necessary permits for the export or transfer of controlled items and how to comply with the requirements of the Export and Import Permits Act and its related regulations. To enquire on the status of an export permit application: Recognized EXCOL users can check the status of an export permit application on-line. Non-recognized users can obtain, from our website (www.exportcontrols.gc.ca), the contact information for the appropriate division responsible for administering the specific control and request a status by providing their export permit application identification (ref ID) number.

  • Introduction to Image Intensifier Tubes
    Introduction to Image Intensifier Tubes General The basic principle of image intensification is identical for all different intensifier versions. Fig. 1: Basic principle An image - ultraviolet, visible light, or near infrared - is projected onto the transparent window of the vacuum tube as shown in Fig. 1. The vacuum side of this window carries a sensitive layer called the photocathode. Light radiation causes the emission of electrons from the photocathode into the vacuum which are then accelerated by an applied DC voltage towards a luminescent screen (phosphor screen) situated opposite the photocathode. The screen's phosphor in turn converts high energy electrons back to light (photons), which corresponds to the distribution of the input image radiation but with a flux amplified many times. The terminology "image intensifier" and "image converter" are frequently confused. In par- ticular, image conversion refers to the transfer from an invisible to a visible spectral range, such as image converters used in night vision. On the other hand, image intensifiers which perform as the name suggests often also function as image converters. Image intensifiers are classified in three categories: first, second, and third generation. Each generation has specific advantages and disadvantages. 1 First Generation Image Intensifiers (Intensifier Diodes) Intensifier tubes in this category feature especially high image resolution, a wide dynamic range (the ability to reproduce the ratio between the bright and dark parts of an image), and low noise. They possess moderate gain in the range of some hundreds of Lumens per Lu- men (Im/Im). First generation tubes utilize only a single potential difference to accelerate electrons from the cathode to the anode (screen).

  • Charge-Coupled Devices (Ccds) Are Well Suited As Synchrotron X-Ray Detectors
    ^c --/-/ Presented at the 5th National Conference on Synchrotron Radiation Instrumentation, Madison, Wisconsin, June 21-25, 1987 CCD SENSORS IN SYNCHROTRON X-RAY DETECTORS* M. G. Strauss, I. Naday+, I. S. Sherman, M. R. Kraimer E. M. Westbrook and N. J. Zaluzec Argonne National Laboratory cntav Rinmn- n Argonne, Illinois 60439, USA o/uoiu -i/ ABSTRACT DE88 002930 The intense photon flux from advanced synchrotron light sources, such as the 7-Gev synchrotron being designed at Argonne, require integrating-type detectors. Charge-coupled devices (CCDs) are well suited as synchrotron x-ray detectors. When irradiated indirectly via a phosphor followed by reducing optics, diffraction patterns of 100 cm2 can be imaged on a 2 cm2 CCD. With a conversion efficiency of ~1 CCD electron/x-ray photon, a peak saturation capacity of >10e x rays can be obtained. A programmable CCD controller operating at a clock frequency of 2 0 MHz has been developed. The readout rate is 5xlO6 pixels/s and the shift rate in the parallel registers is 106 lines/s. The test detector was evaluated in two experiments. In protein crystallography diffraction patterns have been obtained from a lysozyme crystal using a conventional rotating anode x-ray generator. Based on these results we expect to obtain at a synchrotron diffraction images at the rate of ~l frame/s or a complete 3-dimensional data set from a single crystal in ~2 min. * Work supported by the U.
