Document Type and Number:
WIPO Patent Application WO2003020146
Kind Code:
A3
Abstract:
The invention relates to a passive signal sensor (10) of an optical coordinate detection system for medical use, comprising a retroreflection surface (11) for radiation in the ultraviolet, visible or near to middle infrared range. The retroreflection surface is encapsulated in a vapor-tight manner and can be autoclaved, wherein the area covering the housing consists of a transparent material for the radiation used in the coordinate detection system.
