Abstract:
1. Apparatus for automatically inspecting matter, comprising emitting means serving to emit a detection medium, which comprises electromagnetic radiation, to be active at said matter, receiving means in the form of a rotary polygonal mirror arranged to receive from a multiplicity of detection zones at said matter detection medium which has been varied by variations in said matter, a plurality of detecting means serving to receive the varied medium by reflection from the mirror, to detect respective wavelengths of said varied medium substantially simultaneously, and to generate detection data in respect of said wavelengths substantially simultaneously and in dependence upon the variations in said medium, and data-obtaining means connected to said detecting means and serving to obtain said detection data therefrom, the arrangement being such that the beams of the varied medium which are received at said detecting means and emanate from the respective detection zones travel along respective paths from said matter to said mirror which paths converge continuously with respect to each other from said matter to said mirror and do not substantially co-incide with any significant part of the path of the emitted detection medium from the emitting means to the matter.
