Abstract:
1. An endoscopic video measurement system comprising: a proximal operating part, an insertion part, and an interchangeable head which can be attached thereto, wherein the proximal operating part comprises a connection for electrical and optical supply for the system, a first optical transmitter for object illumination and electrical supply and transmission lines for an electronic image sensor, which is arranged in a distal end portion of the insertion part, are provided in the insertion part, the interchangeable head comprises a second optical transmitter for the object illumination and object imaging, a single-mode glass fiber in the distal end portion of the insertion part, an opening in a distal end surface of the insertion part that transmits light out of the insertion part, an entrance surface of the interchangeable head that receives light from the opening when the interchangeable head is attached to the insertion part, and an optical system associated with the single-mode glass fiber in the distal end portion of the insertion part that produces a collimated measurement beam bundle by collimating the light transmitted out of the insertion part to increase positioning tolerances between the insertion part and the interchangeable head.
