ABSTRACT:
Optical monitoring apparatus for detecting the angles at which light rays leave a material surface scanned by a light bead such as an incident laser beam includes a row of individual Fresnel lenses arranged edgewise directly adjacent each other to focus light leaving the surface onto respective arrays of photodetectors arranged in their focal planes.
The outputs from the photodetectors are connected together by processing means to allow evaluation of their output signals. The row of Fresnel lenses may also be used for other optical monitoring purposes.
