Abstract

The invention relates to an optical arrangement which can be used in particular as a 360° optical system for applications in which the use of a camera with a classic objective in the direct beam path is not possible. The invention proposes an optical arrangement which comprises at least one belt lens (1) and at least one optical sensor (2) that is at least partly arranged in the beam path of the at least one belt lens (1). In particular, optical signals pass through the belt lens without being reflected. Thus, a belt lens optical system suitable for a 360° view is provided in combination with a centrally arranged image sensor system, which can be used in order to reliably detect and analyze moving objects, preferably from a bird's-eye view. The belt lens optical system in combination with the image sensor system constitutes a 360° monitoring system which operates effectively and which can be integrated easily into technological processes. A preferred embodiment is characterized by a belt lens design with a fast lens speed and a central image sensor system for monitoring the surroundings with a movement analyzing function.
