Abstract:
Methods and devices are provided for the trapping, including optical trapping; analysis; and selective manipulation of particles on an optical array. A device parcels a light source into many points of light transmitted through a microlens optical array and an Offner relay to an objective, where particles may be trapped. Preferably the individual points of light are individually controllable through a light controlling device. Optical properties of the particles may be determined by interrogation with light focused through the optical array. The particles may be manipulated by immobilizing or releasing specific particles, separating types of particles, etc .
Abstract:
An imaging system. An array of light sources and an array of lenses corresponding to the light sources and having optical axes substantially parallel to one another are provided. The lenses produce collimated output beams. An afocal optical relay having an optical axis substantially parallel to the optical axes of the lenses is also included, the array of lenses being positioned relative to the afocal optical relay so as to form an optical system that produces an image of each collimated output beam on an image plane, each image having a prescribed depth of focus and spot size. The light sources preferably are lasers producing an array of respective laser beams having high intensity and a long waist. A system for writing information on a light-sensitive label includes the imaging system. Methods of imaging and of writing information on a light-sensitive label are also provided.

Abstract:
L'instrument optique, destiné à être utilisé sur satellite, permet d'observer simultanément ou quasi-simultanément dans deux directions angulairement séparée. Il comprend au moins deux télescopes (TA, TB) ayant des directions d'observation angulairement écartées, ayant chacun une pupille de sortie réelle et accessible et des champs images respectifs plans ou superposables, de largeur au moins 5 fois supérieure à celle de la pupille dans une direction déterminée. Des moyens optiques placés à la pupille de sortie sont disposés de façon à former les champs images dans un plan focal commun en recouvrement sauf dans des zones latérales dont la largeur est sensiblement celle de la pupille de sortie des télescopes. Dans le plan focal commun, un ensemble de plusieurs détecteurs matriciels sont disposés et orientés sur la zone de superposition des champs images des télescopes dans le front d'onde.

Abstract:
The present disclosure relates to an improved optical arrangement for an optical imaging system or the like, comprising: an optical device; a digital micromirror device having a plurality of individually addressable micromirrors; a convex mirror; and a concave mirror concentric to the convex mirror. The convex mirror and the concave mirror define an optical triplet which is located in an optical path with the digital micromirror device and the optical device. The concave mirror comprises two concave mirror sections, one or both concave mirror sections being moveable relative to the convex mirror so as to control an image mapping between the digital micromirror device and the optical device.
