An endoscope measures the topography of a surface. The endoscope contains a projection unit and an imaging unit. The projection unit and the imaging unit are arranged successively in relation to an axis of the endoscope. The configuration of the projection unit and the imaging unit arranged axially behind one another on the axis permits a significantly smaller endoscope configuration.本発明は、投影ユニット(6)と撮像ユニット(8)とを備え、表面(4)のトポグラフィを測定するための内視鏡に関し、投影ユニットと撮像ユニットとは内視鏡軸(10)に関して相前後して配置されている。【選択図】図6
