IMAGE IMPROVEMENT [6 records]

Record 1 2013-12-19

English

Subject field(s)
  • Scientific Instruments
  • Photoelectricity and Electron Optics
CONT

Scanning transmission electron microscopy(STEM) combines the principles of transmission electron microscopy and scanning electron microscopy and can be performed on either type of instrument. Like TEM [transmission electron microscopy], STEM requires very thin samples and looks primarily at beam electrons transmitted by the sample. One of its principal advantages over TEM is in enabling the use of other signals that cannot be spatially correlated in TEM, including secondary electrons, scattered beam electrons, characteristic X-rays, and electron energy loss. Like SEM [scanning electron microscopy], the STEM technique scans a very finely focused beam of electrons across the sample in a raster pattern. Interactions between the beam electrons and sample atoms generate a serial signal stream, which is correlated with beam position to build a virtual image in which the signal level at any location in the sample is represented by the gray level at the corresponding location in the image. Its primary advantage over conventional SEM imaging is the improvement in spatial resolution.

Subject field(s)
  • National Bodies and Committees (Canadian)
  • Dog and Cat Breeding
  • Police
OBS

The Canadian Police Canine Association was formed in 1978 by several dog handlers who were interested in seeing how their counterparts were performing in the same job as themselves. The CPCA has grown considerably since those early years, however, our main objectives have remained the same : to promote friendship and brotherhood between all those interested in the training and utilization of the Police Service Dog; to unite and assist Police Departments in the training and continued improvement of Police Service Dogs; to establish and conduct regular “Police Service Dog Trials” for the purpose of establishing levels of proficiency; to provide educational material through publications and a website; to coordinate the exchange of any advanced techniques of training in the utilization of Police Service Dogs; to improve the image of the Police Service Dog to the general public.

Record 4 2008-01-14

English

Subject field(s)
  • Photography
CONT

An improvement over the first "panoramic" system involved eliminating the rotation of the photographic apparatus, and instead disposing the object to be photographed in front of the objective lens and rotating the object itself. As in a "panoramic" system, the image of the object is recorded on a photographic film which is moved linearly at the same speed as the speed of rotation of the object. Such a system is known as a "periphotographic system".

French

Domaine(s)
  • Photographie
DEF

[Système qui] permet de reproduire sur un plan, avec n'importe quel appareil photographique, l'image de toute la surface latérale d'un objet de forme de révolution.

OBS

[Le banc périphotographique] permet, à partir d'une motorisation, de transmettre le mouvement de rotation au plateau qui supporte l'appareil photographique.

OBS

Le banc périphotographique [...] pourra en effet servir non seulement à étudier les vases antiques mais aussi tout autre objet approximativement cylindrique.

Subject field(s)
  • Launching and Space Maneuvering
DEF

... the time it takes the satellite to complete a full cycle and pass exactly above the same point.

CONT

A significant improvement of RADARSAT-2 over its predecessor and other synthetic aperture radar satellites is its ability to image on either the left or right, nominally requiring 10 minutes to switch between either side. This capability will reduce the re-visit time for imaging opportunities of any region.

OBS

repeat cycle: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).
