Abstract
The invention is directed to a touch probing device for inspecting an object which includes a fixed part, movable part coupled to and movable with respect to the fixed part for measuring the motion between the fixed and the movable parts, and a contact means coupled to the movable part for contacting a surface of the object. The contact means is preferably coupled to the movable part via a shock absorber. Alternatively, or in addition weight compensating means are provided for compensating the weight of the movable part. The weight compensating means preferably uses a magnetic field for compensating the weight of the movable part.
Claims28
A touch probing device for inspecting an object, comprising:
- a fixed part,
- a first movable part coupled to and movable with respect to the fixed part,
- measuring means for measuring the displacement of the fixed part relative to the first movable part and for supplying a measuring signal indicative of the relative displacement, and
- contact means coupled to the movable part for contacting a surface of an object,
- wherein
- the contact means is coupled to the first movable part via a shock absorber.
A touch probing device for inspecting an object, comprising
- a fixed part,
- a movable part coupled to the fixed part in such that it allows for a motion of the movable part with respect to the fixed part,
- measuring means for measuring the displacement of the fixed relative to the movable part and for supplying a measuring signal indicative of the relative displacement,
- contact means coupled to the movable part for contacting a surface of the object, and
- weight compensating means for compensating the weight of the movable part,
- wherein
- the weight compensating means uses a magnetic field for compensating the weight of the movable part, wherein the magnetic field generates a quasi-linear compensating force with an excursion range of the movable part relative to the fixed part.
