Radial lens assembly with optical zoom device and optical sensor having such a radial lens assembly

摘要

The present invention relates to a radial lens assembly (100) for generating an optical image of a detection area. The radial lens assembly (100) includes a central light redirecting unit (120) that is configured and arranged to break and directionally transmit light (10) from the sensing area. The radial lens assembly (100) further comprises a light collection unit (160) configured and arranged to receive light (12) propagated from the central light redirecting unit (120) and to generate the optical image on an observation surface (110) of the light collection unit (160). to project. The central light redirecting unit (120) comprises a number of optical rings (122, 124, 126) fixedly disposed in the radial lens assembly (100, 200), wherein a respective one of the plurality of optical rings (122, 124, 126) is an outer one Mantle surface comprises (122-1; 124-1; 126-1) which faces in the radial direction, and wherein the central light deflection unit (120) is arranged such that the light (10) coming out of the detection area is deposited on the respective outer mantle surface (12). 122-1; 124-1; 126-1). According to the present invention, the central light redirecting unit (120) further comprises an optical zooming device (127) for zooming in and out of an observation portion of the detection range, the observation portion being magnified by zooming in on the observation surface (110), and wherein the observation section is reduced in size by the zooming out on the observation surface (110).
