Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
A device for recording object contours in which a contour of an object is marked and the marked contour is sensed and recorded optically, characterized in that an optical system of the device comprises a mirror system comprising at least three mirrors (13) arranged about the object to cover the entire contour, a lens (14) associated with each mirror to project sub-images of the marked contour onto a common collecting member (15) to combine the sub-images for the formation of a single image of the marked contour and project it onto the input surface of an image sensing device (17) which, together with the collecting member, is positioned on an isocentric axis (4).
Claim 2
Independent Claim
113 words
A device for recording object contours in which a contour of an object is marked and the marked contour is sensed and recorded optically, characterized in that an optical system of the device comprises a mirror system comprising at least three mirrors (13) arranged about the object to cover the entire contour, a lens (14) associated with each mirror to project sub-images of the marked contour onto a common collecting member (15) to combine the sub-images for the formation of a single image of the marked contour and project it onto the input surface of an image sensing device (17) which, together with the collecting member, is positioned on an isocentric axis (4).
Claim 3
Dependent Claim
43 words
A device as claimed in Claim 1, characterized in that the lenses (4) form an angle-corrected faithful sub-image of a contour portion on the optical collecting member which forms from the sub-images a focussed, faithful image of the contour on the image-forming device.
Claim 4
Dependent Claim
35 words
A device as claimed in Claim 2, characterized in that the mirror system is of duplicate construction with mutually equal reading angles and mutually equal optical beam path lengths to a common optical collecting member.
Claim 5
Dependent Claim
26 words
A device as claimed in Claim 1, 2 or 3, characterized in that the image-sensing device comprising a television camera to which a monitor is adapted.
Claim 6
Dependent Claim
16 words
A device as claimed in Claim 4, characterized in that a video memory is associated therewith.
Claim 7
Dependent Claim
28 words
A device as claimed in Claim 4 or 5, characterized in that an analog-to-digital converter and a computer are associated therewith for the recording and comparison of contours.
Claim 8
Dependent Claim
20 words
A medical irradiation apparatus comprising a device for recording object contours as claimed in any one of the preceding Claims.
Claim 9
Independent Claim
25 words
An apparatus for a treatment of work pieces, comprising a device for recording object contours as claimed in any one of Claims 1 to 6.
