Document Type and Number:
Japanese Patent JP2010507154
Kind Code:
A
Abstract:
The invention relates to an arrangement (10) and a method for detecting an object (18) arranged on a body (14). The arrangement comprises a vibration device (12), which sets the body (14) in a mechanical vibration of predetermined vibration frequency and predetermined vibration phase, an emission device (20) which emits in the direction of the body (14) a coherent electromagnetic detection radiation (26), the radiation frequency of which is selected such that it is reflected at least in part by the body (14) and the object (18) to be detected, a receiver device (30), which receives the radiation (28) reflected by the body (14) and the object (18), and an evaluation device (32) which filters out of the radiation (28) received the portions having the predetermined vibration frequency and evaluates them with respect to their vibration phase difference from the predetermined vibration phase.
