Proximity detector for use with an imaging device, method to distinguish in the case of an imaging device and imaging system with a proximity detector

摘要

Proximity detector (10) for use with an imaging means (20), comprising a flat antenna (12), which on the imaging device (20) can be arranged and which is designed, an evanescent shaft (18) to generate a signal generator unit (32), which is designed to generate an alternating signal, and this alternating signal for generating an evanescent shaft (18) of the flat antenna (12), and a sensor unit (34), which is designed for this purpose, a change in an electrical parameter of the flat antenna (12) during the production of a evanescent shaft (18) and in the case of penetration of an object (52) in the region of the evanescent shaft (18) can be seen, the detection in a detection signal and the detection signal to convert to provide.
