Measuring endoscope

摘要

An endoscope measures the topography of a surface. The endoscope contains a projection unit and an imaging unit. The endoscope is characterized in that an objective unit is provided as a component both of the projection unit and the imaging unit. By the integration of the projection unit and the imaging unit, which both use a common objective unit, the structural volume required by both units is reduced resulting in a smaller endoscope.

主权项

1. An endoscope for measuring a topography of a surface, the endoscope comprising:
a projection unit outputting projection rays; an imaging unit receiving imaging rays; an objective unit being both a component of said projection unit and also of said imaging unit, said objective unit receiving and conditioning both the projection rays and the imaging rays; and said projection unit having an annular mirror lens being rotationally symmetrical relative to an optical axis, said annular mirror lens disposed adjacent to and upstream from said objective unit.
