Low light level television (LLLTV) is a type of electronic sensing device, usually a CCD camera sensitive to wavelengths above the normal "visible" (0.4 to 0.7 micrometre) wavelengths, and into the short-wave Infrared - usually to about 1.
0 to 1.1 micrometres. This allows viewing of objects in extremely low light levels, where they would not be seen by the naked eye.
LLLTVs tend to be more affordable than infrared cameras, which typically cover ranges from 3 to 5Â m (MWIR)or 8 to 12Â m (LWIR)

History of CCD camera
Originally called Remsheg (or Ramshag), meaning "the place between" in the Mi'kmaq language. The homes of the Acadians who lived in the village were burned as part of the Bay of Fundy Campaign (1755) during the French and Indian War. Wallace and near-by Tatamagouche, Nova Scotia were the first villages in Acadia to be burned because they were the gateway through which Acadians supplied the French Fortress Louisbourg.
Fourteen other ranks of the Royal Fencible American Regiment took up land grants in Remsheg following the American Revolutionary War, as did the Westchester Refugees from Westchester county, New York (sometimes known as DeLancey's 'Cowboys' for their cattle raids to help the British cause). Scottish immigrants followed and the village was renamed Wallace in honour of Scottish folk hero William Wallace as well as the first colonial treasurer of Nova Scotia, Michael Wallace. The village is located at the mouth of the Wallace River where it meets Wallace Bay on the Northumberland Strait.
Wallace Harbour is deep and straight, at one time being used by large ships hauling lumber and quarry stone. The Wallace River is a major river in northern Cumberland County and was once home to quarries and lumber mills and used to transport their products by sailing ships. Many of these ships were built in Wallace and surrounding areas.
Construction of the Montreal and European Short Line Railway Company began on the north shore of Nova Scotia in 1888, with the aim being to link Oxford with Pictou and onward to a superport under consideration for Canso. The section between Oxford and Pictou opened in 1890 and was known as the "Short Line" - in reference to the shorter distance between New Brunswick and Pictou County, rather than following the main line south from New Brunswick to Truro. Wallace's importance as a shipping port, quarrying industries, and small-scale manufacturing saw a spur line built from the Short Line at Wallace Station, approximately 3 kilometres inland, to the south of the village.
By the post-war years, Wallace's importance for marine traffic declined and its small shipping port fell into disrepairthe Canadian Coast Guard even began decommissioning its lighthouses there. The railway connection was removed and rail service in the area was abandoned in the mid-1980s. The village's primary mode of transportation is by automobile and the village is situated on Trunk 6 which hosts a scenic route named the Sunrise Trail.
Discovery of CCD camera
On the night this minor planet was discovered at Brorfelde Observatory, Poul Jensen also discovered the Jupiter trojan (6002) 1988 RO, the 12-kilometer size main-belt asteroid (9840) 1988 RQ2, as well as (12689) 1988 RO2, (14364) 1988 RM2, (14837) 1988 RN2, and (24664) 1988 RB1, all main-belt asteroids of inner, middle and outer region of the asteroid belt, respectively. A first precovery was taken at Palomar Observatory in December 1954, extending the asteroid's observation arc by 34 years prior to its discovery.

Basic principlesComparison with other techniques of CCD camera
Advantages- Unlike several other flow imaging techniques, PLIF may be combined with particle image velocimetry (PIV).
This allows for the simultaneous measurement of a fluid velocity field and species concentration. Limitationsflowfield must contain molecular species with an optical resonance wavelength that can be accessed by laser temperature measurements typically require two laser sources velocity measurements typically practical only for high Mach number flows (near sonic or supersonic) signal-to-noise ratio often limited by detector shot-noise fluorescence interferences from other species, especially from hydrocarbons in high pressure reacting flows attenuation of laser sheet across flow field or reabsorption of fluorescence before it reaches detector can lead to systematic errors
Physical characteristics of CCD camera
1988 RA1 is an assumed, carbonaceous C-type asteroid, while most larger Jupiter trojans are D-types. It has a typical VI color index of 0.
97. LightcurveIn February 1994, 1988 RA1 was observed by Stefano Mottola and Anders Erikson at La Silla Observatory in Chile, using the ESO 1-metre telescope and its DLR MkII CCD-camera. The photometric observations were used to build a lightcurve showing a rotation period of 12.

Orbit and classification of CCD camera
1988 RA1 is a dark Jovian asteroid in a 1:1 orbital resonance with Jupiter. It is located in the trailering Trojan camp at the Gas Giant's L5 Lagrangian point, 60 behind its orbit (see Trojans in astronomy).
It is also a non-family asteroid of the Jovian background population. It orbits the Sun at a distance of 4. 65.
8Â AU once every 11 years and 10 months (4,333 days; semi-major axis of 5.2Â AU). Its orbit has an eccentricity of 0.

Mission of CCD camera
Like its successor UoSAT-2 it carried a CCD camera and a Digitalker speech synthesiser, and transmitted telemetry data on a 145.
826Â MHz beacon at 1200 baud using asynchronous AFSK. The Astrid package sold by British firm MM Microwave, consisting of a fixed frequency VHF receiver set and software for the BBC Micro, could display the telemetry frames from either UoSAT-1 or UoSAT-2. UoSAT-1's solar arrays were of an experimental design reused for UoSAT-2.

Biography of CCD camera
D'Onofrio graduated in Law at the University of Naples Federico II and achieved a Master in Law at the Harvard University under the guidance of Henry Kissinger, teaching a few years later Public Law at the Sapienza University of Rome.
In 1982, D'Onofrio joined the Christian Democracy, with which he has been elected to the Senate in 1983 and to the Chamber of Deputies in 1987 (he entered in Parliament only in 1990, replacing his colleague Giovanni Galloni who was elected to the CSM) and in 1992. From 12 April 1991 to 24 April 1992, he joined the Andreotti VII Cabinet as undersecretary at the Ministry for Constitutional Reforms and at the Ministry for Regional Affairs. In 1994, he joined Pier Ferdinando Casini's Christian Democratic Centre, allied with Silvio Berlusconi's Forza Italia, and is re-elected one more time to the Chamber of Deputies.
In May 1994, D'Onofrio is appointed Minister of Public Education in the Berlusconi I Cabinet. He is later re-elected to the Senate in 1996, in 2001 and in 2006. From 1996 to 2001, D'Onofrio has been the group leader in Palazzo Madama of the Christian Democratic Centre, while from 2006 to 2008 he has been the group leader of the Union of the Centre.
He decided not to run again for a seat in Parliament in 2008. He is currently a columnist of the online newspaper Formiche.net.
Working of CCD camera
A PLIF setup consists of a source of light (usually a laser), an arrangement of lenses to form a sheet, fluorescent medium, collection optics and a detector. The light from the source, illuminates the medium, which then fluoresces. This signal is captured by the detector and can be related to the various properties of the medium.
The typical lasers used as light sources are pulsed, which provide a higher peak power than the continuous-wave lasers. Also the short pulse time is useful for good temporal resolution. Some of the widely used laser sources are Nd:YAG laser, dye lasers, excimer lasers, and ion lasers.
The light from the laser (usually a beam) is passed through a set of lenses and/or mirrors to form a sheet, which is then used to illuminate the medium. This medium is either made up of fluorescent material or can be seeded with a fluorescent substance. The signal is usually captured by a CCD or CMOS camera (sometimes intensified cameras are also used).
Timing electronics are often used to synchronize pulsed light sources with intensified cameras.
