Abstract (en)
[origin: WO2009156350A1] The invention relates to a method for detecting the contact of at least one measuring needle (1) with a device under test (3), wherein a transmitted light image of the at least one measuring needle (1) is generated on at least one line scan camera (6) during lateral illumination, the at least one measuring needle (1) and the device under test (3) are moved closer together, and the contact of the at least one measuring needle (1) with the device under test (3) can be detected by the deflection of the measuring needle (1) and the simultaneous displacement of the image on the line scan camera (6).
