Title:
IMPROVED OPTICAL SURFACE ROUGHNESS MEASURING DEVICE, DEVICE FOR CONTROLLING THE POSITIONING OF THE PRISM THEREOF, METHOD FOR CONTROLLING THE PRISM POSITIONING AND METHOD FOR POSITIONING SAID PRISM
Document Type and Number:
WIPO Patent Application WO2005095046
Kind Code:
A3
Abstract:
The inventive optical measuring device comprises a system (14) for illuminating a surface area (12) connected upstream of a light source by light transmitting means (18) and a system (22) for receiving the image of said surface area (12). The light source comprises a laser source and said light transmitting means (18) comprises a single-mode transmission optical fibre (20). A device for controlling the positioning of the prism (34) of said device, a method for controlling the prism (34) positioning and method for positioning said prism using the method for controlling said positioning are also disclosed.
