Title
(EN) TRANSMISSION MODE 1.06$g(m)M PHOTOCATHODE FOR NIGHT VISION AND METHOD
(FR) PHOTOCATHODE SEMI-TRANSPARENTE A SENSIBILITE 1.06 $g(m)M POUR VISION NOCTURNE ET PROCEDE
Abstract
(EN)
An improved photocathode (12) and image intensifier tube (10) are disclosed along with a method for making both the tube (10) and photocathode (12). The disclosed image intensifier tube (10) creates a visible light image (20) from an image emitting photons (22). The tube (10) comprises a photocathode (12) having an indium-gallium-arsenide active layer (26) and an aluminum-gallium-arsenide window layer (28). The photocathode (12) is operable to emit electrons (23) in response to the photons (22). A display apparatus is coupled to the photocathode (12) and is operable to transform the emitted electrons (23) into a visible light image (24). An embodiment of the invention is capable of detecting 1.06 $g(m)m radiation.
(FR)
L'invention se rapporte à une photocathode (12) et à un tube intensificateur d'image (10) perfectionnés, ainsi qu'à un procédé de fabrication du tube (10) et de la photocathode (12). Le tube intensificateur d'image (10) crée une image en lumière visible (20) à partir de photons (22) émetteurs d'image. Le tube (10) comprend une photocathode (12) comportant une couche active d'indium-gallium-arséniure (26) et une couche fenêtre d'aluminium-gallium-arséniure (28). La photocathode (12) est conçue pour émettre des électrons (23) en réponse aux photons (22). Un appareil d'affichage est raccordé à la photocathode (12) et peut être utilisé pour transformer les électrons émis (23) en une image en lumière visible (24). Dans un mode de réalisation de l'invention, le dispositif peut détecter un rayonnement à 1.06 $g(m)m.
