Method for the Detection of Objects Enclosed in a Medium, and Measuring Apparatus for Carrying Out Said Method

摘要

The invention relates to a method for detecting objects ( 12 ) that are enclosed in a medium ( 10 ). According to said method, a test signal ( 18 ) that makes it possible to obtain information about the position of the enclosed object ( 12 ) is generated via at least one transmission coil ( 14 ) and at least one receiving conductor loop system ( 16 ) which are inductively coupled to each other The frequency (f_M) of the test signal (U_M) is modified in accordance with the signal intensity of the detected test signal ( 18 ). The invention further relates to a measuring apparatus, especially a hand-held locating device ( 24, 124 ), for carrying out the disclosed method.
