专利汇可以提供Apparatus for automatic inspection of materials专利检索,专利查询,专利分析的服务。并且Apparatus for automatically inspecting materials to locate defects or flaws by directing light onto or through the material and by providing an electrical signal from the light influenced by the material. A scanning means serves to scan the material. In one construction the scanning means is a rotatable body with light-reflective surfaces on its periphery the body being used to direct the light from a source onto the material as a line scan. In another construction the scanning means is a rotatable drum with lenses disposed around its periphery, the lenses serving to receive light influenced by the material. A static reflecting means which may comprise a cylindrical mirror or a special arrangement comprising a beam splitting device combined with one or more pieces of retroreflective tape is arranged to direct light to or from the material. The rotatable body and the detecting means producing the electrical signal are located at conjugate positions in relation to the optical system comprising the static reflecting means and the material. Two objects are at conjugate positions, that is in mutual conjugacy, when rays of light diverging from either object will be brought to focus at the other object. Alternatively the source and the rotatable drum are located at conjugate positions in relation to the said optical system.,下面是Apparatus for automatic inspection of materials专利的具体信息内容。
