The resolution of an optical imaging system – a microscope, telescope, or camera – can be limited by factors such as imperfections in the lenses or misalignment. However, there is a fundamental maximum to the resolution of any optical system which is due to diffraction. An optical system with the ability to produce images with angular resolution as good as the instrument's theoretical limit is said to be diffraction limited.  2, record 2, English, - diffraction%20limited

Limite de diffraction – Les instruments optiques contiennent le plus souvent une chambre noire. La lumière passant par l'ouverture de la chambre noire subit une diffraction. Or la diffraction limite le pouvoir de résolution des instruments optiques : un objet ponctuel donne une image «floue», appelée tache de diffraction. Si deux détails d'un objet sont trop proches, les taches de diffraction se chevauchent et il devient impossible d'obtenir des images séparées de ces détails.  3, record 2, French, - limit%C3%A9%20par%20la%20diffraction

The unique and distinctive characteristics of LUCIE allow it to surpass currently available underwater cameras and make it a tool of choice for activities involving search and rescue, investigation and underwater surveillance. The camera can identify targets at up to five times greater distances than conventional cameras. LUCIE possesses the ability to eliminate backscattering-this elimination is unavailable on conventional cameras and enables the camera's imaging system to focus on light reflected from objects a specific distance away while filtering out light reflected from particles in suspension.  1, record 4, English, - laser%20underwater%20camera%20image%20enhancer

Ultra-Fine mode, available on RADARSAT-2, will acquire images at a spatial resolution of 3 meters. In this mode, the radar operates with sampling rate, therefore the ground coverage is limited(10 to 20 km) to keep the acquisition within the recording limits. The Ultra-Fine imaging mode will provide the best resolution available commercially with a spaceborne SAR system. This capability will allow the ability to detect more clearly targets that are closely spaced and provide enhanced definition of other targets, thereby reducing ambiguities and increasing confidence in the data.  3, record 5, English, - ultra%2Dfine%20mode

Le mode Ultra-Fin de RADARSAT-2 permettra l'acquisition d'images avec une résolution spatiale de 3 mètres, soit la meilleure résolution spatiale disponible commercialement par télédétection radar. Lors de l'utilisation de ce mode, le radar fonctionne avec une fréquence d'acquisition très élevée. Par conséquent, la fauchée au sol est limitée entre 10 et 30 km afin de ne pas excéder les capacités d'enregistrement. Le mode Ultra-Fin permettra de détecter les objets plus clairement et améliorera la discrimination entre les surfaces observées, facilitant ainsi l'analyse et l'interprétation des données.  4, record 5, French, - mode%20ultra%2Dfin
