摘要:
A 3-D camera for obtaining an image of at least one surface of at least one object. The camera comprises a light source, arranged to illuminate the object, wherein a light beam emitted from the light source defines a projection optical path. The camera also includes at least one first aperture having a first predetermined size, interposed in the projection optical path such that the light beam passes through it. An image sensor receives light back-scattered by the object, the back-scattered light defining an observation optical path. At least one second aperture having a second predetermined size, is interposed in the observation optical path such that the back-scattered light passes through it. In one example embodiment of the invention, the first predetermined size is greater than the second predetermined size, and at least one optic is arranged in both the projection and observation optical paths.
