[Laser profilometry--a measuring system for biomedical applications].
A non-contacting opto-electronic measurement station is described which readily lends itself for measuring delicate or fragile surfaces, such as those represented by a skin or cornea. A whole family of autofocussing optical sensors is available with differing specifications each suited to a particular application area. The sensors feature a spot footprint of 1 micron, a measuring range of up to 1 mm and a resolution of up to 10 nm. The measuring station is suitable for measuring 3D surface profiles, and a comprehensive software package is available which allows scientific treatment of the data.
