Laser Rangefinder
A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object. The most common form of laser rangefinder operates on the time of flight principle by sending a laser pulse in a narrow beam towards the object and measuring the time taken by the pulse to be reflected off the target and returned to the sender. Due to the high speed of light, this technique is not appropriate for high precision sub-millimeter measurements, where triangulation and other techniques are often used. Pulse The pulse may be coded to reduce the chance that the rangefinder can be jammed. It is possible to use Doppler effect techniques to judge whether the object is moving towards or away from the rangefinder, and if so, how fast. Precision The precision of the instrument is determined by the rise or fall time of the laser pulse and the speed of the receiver. One that uses very sharp laser pulses and has a very fast detector can ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optoelectronics
Optoelectronics (or optronics) is the study and application of electronic devices and systems that find, detect and control light, usually considered a sub-field of photonics. In this context, ''light'' often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible light. Optoelectronic devices are electrical-to-optical or optical-to-electrical transducers, or instruments that use such devices in their operation. '' Electro-optics'' is often erroneously used as a synonym, but is a wider branch of physics that concerns all interactions between light and electric fields, whether or not they form part of an electronic device. Optoelectronics is based on the quantum mechanical effects of light on electronic materials, especially semiconductors, sometimes in the presence of electric fields. * Photoelectric or photovoltaic effect, used in: ** photodiodes (including solar cells) ** phototransistors ** photomultipliers ** ...

International Defence Exhibition And Seminar
The International Defence Exhibition and Seminar, more commonly referred to as IDEAS, is a defence sector event, held biannually, in Pakistan. Since its inception by President Pervez Musharraf in 2000, it has grown to include more than 54,000 trade visitors, 290 delegates members (from 43 countries), 133 national exhibitors and 294 exhibitors from around the world in latest IDEAS 2016 held from 22 to 25 November 2016. The Pakistan government attaches a high level of importance to IDEAS; despite the fact that it attracts a large number of delegates, it is seen as a vehicle for facilitating their own indigenous arms trade. The level of political involvement has been known to reach the highest echelons, with President Asif Ali Zardari personally inviting the Amir of Kuwait Sheikh Sabah Al-Ahmad Al-Jaber Al-Sabah to the event in 2008 in order to boost the chances of Pakistan's export of its indigenously developed al-Khalid main battle tanks.

AN/PVS-14
The AN/PVS-14 Monocular Night Vision Device (MNVD) is in widespread use by the United States Armed Forces as well as NATO allies around the world. It uses a third generation image intensifier tube, and is primarily manufactured by Litton Industries (Now L-3 Warrior Systems) and Elbit Systems of America (formerly Harris Night Vision, formerly Exelis, formerly ITT). It is often used 'hands free' using a head harness or attached to a combat helmet such as the PASGT, MICH TC-2000 Combat Helmet, Advanced Combat Helmet, Marine Lightweight Helmet or IHPS. It can also be used as a weapons night sight. In addition, it was part of the equipment fielded in the U.S. Army's Land Warrior program. Morovision Night Vision was the law enforcement distributor of the NEPVS-14 for ITT. The designation AN/PVS translates to Army/Navy Portable Visual Search, accor ...

AN/PVS-4
AN/PVS-4 (Night Vision Sight, Individual Served Weapon, AN/PVS-4) is the U.S. military designation for a specification of the first second generation passive Night vision device. The AN/PVS-4 first saw widespread use during the Gulf War and later some deployment in the Iraq War and has since been replaced by modern third-generation weaponsights. Introduction Although passive night vision technology capable of allowing vision under ambient starlight conditions has existed since the 1950s, it was not until the AN/PVS-4 was developed that a practical, high quality device that met military requirements was first made available. Unlike earlier passive starlight weaponscopes the AN/PVS-4 provided a high quality image without significant distortion, could adjust to changing ambient light conditions, was able to take multiple reticles to operate in many roles and had protective features allowing it to shut down in the event of exposure to bright light, but still recover in time after ...

Thermal Imaging
Infrared thermography (IRT), thermal video and/or thermal imaging, is a process where a thermal camera captures and creates an image of an object by using infrared radiation emitted from the object in a process, which are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 μm) and produce images of that radiation, called thermograms. Since infrared radiation is emitted by all objects with a temperature above absolute zero according to the black body radiation law, thermography makes it possible to see one's environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds; humans and other warm-blooded animals become ...

Night Vision Device
A night-vision device (NVD), also known as a night optical/observation device (NOD), night-vision goggle (NVG), is an optoelectronic device that allows visualization of images in low levels of light, improving the user's night vision. The device enhances ambient visible light and converts near-infrared light into visible light which can be seen by the user; this is known as I2 ( image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum. A night vision device usually consists of an image intensifier tube, a protective housing, and may have some type of mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front lens (ie. objective lens) on NVDs to protect the latter from damage by environmental hazards and some can incorporate [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Optical Physicist
Optics is the branch of physics that studies the behaviour and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behaviour of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties. Most optical phenomena can be accounted for by using the classical electromagnetic description of light. Complete electromagnetic descriptions of light are, however, often difficult to apply in practice. Practical optics is usually done using simplified models. The most common of these, geometric optics, treats light as a collection of rays that travel in straight lines and bend when they pass through or reflect from surfaces. Physical optics is a more comprehensive model of light, which includes wave effects such as diffraction and interference that cannot be ...
