Abstract
(A1) Die Erfindung betrifft ein Bilderfassungssystem zur Rundumsicht aus zeilenförmig angeordneten optischen Kanälen mit einer Mikrolinse und einem in dessen Brennebene liegenden Detektor. Die Kameraeinheit ist dabei auf einer rotierenden oder rotationsschwingenden Rotationsachse montiert, wodurch eine Rundumsicht des Bilderfassungssystems ermöglicht wird. Verwendung finden derartige Bilderfassungssysteme in der Medizintechnik, auf Fahrzeugen, zur Inspektion von lochartigen Ausnehmungen sowie zur 360°-Bilderfassung in Räumen.

 

DE 102006019124 A1 UPAB: 20071119 NOVELTY - The system has a camera unit formed from linearly arranged optical channels with a micro lens (2), where a detector extracts a pixel from a micro-image behind the micro-lens. The camera unit is mounted on a rotating or rotational swinging axis (4). A drive (5) e.g. engine, a stepper motor or a coil in connection with a spring, is coupled in the axis of rotation. The optical axis of the individual optical channels has different inclinations such that they represent a function of the distance of the optical channel from the center of the side of the camera unit turned to the image. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for recording an image in circumferential visibility. USE - Used in a medical technology e.g. endoscopy, for recording image and inspecting hole-like recesses. Can also be utilized in a vehicle (claimed). ADVANTAGE - The camera unit is mounted on the rotating or rotational swinging axis, where the drive is coupled in the axis of rotation, thus achieving a mechanical balancing in the image recording system and avoiding the undesired and the inadvertent change of the line of sight of the camera and providing the stable mechanical structure for the system.
