Patent

CA 2207439

The invention is intended for use in instrument making and concerns in particular optical location devices. The invention in essence comprises a pulsed light source (1) with transmission optics (2), a synchronisation unit (3), control unit (4), optical image receiver (5) with a receiving objective (6), and an objective control unit (7). With the proposed device, it is possible to obtain an image of uniform brightness of objects at differing distances using either natural light to illuminate the observation zone or artificial lighting and to differentiate between individual objects within the said zone.

L'invention est utilisée dans la production d'instruments et concerne en particulier des dispositifs de localisation optique. L'invention comprend principalement une source de lumière pulsée (1) avec un système optique de transmisison, une unité de synchronisation (3), une unité de commande (4), un récepteur d'image optique (5) équipé d'un objectif récepteur (6), ainsi qu'une unité de commande d'objectif (7). Le dispositif de l'invention permet d'obtenir des images de brillance homogène, d'objets situés à différentes distances, la zone d'observation étant éclairée au moyen de lumière naturelle ou au moyen de lumière artificielle, et permet de différentier des objets individuels à l'intérieur de ladite zone.
