摘要： A method and apparatus for identifying a material type in an article, such as wholly or partly transparent bottle of plastic or glass, including, with the aid of a detector station, irradiating the article with rays from an infrared radiation source, detecting rays which have passed through the article non-absorbed, and then carrying out a correlation analysis of such detected rays. The article is made to pass through the detector station in a continuous or discontinuous movement. The rays from the radiation source are successively filtered by the filters consisting of wholly or partly transparent materials which have different spectral characteristics. The rays filtered by the filters and non-absorbed by the article are intercepted in order to form a sequence of measured values representing characteristic transmission signatures of the article. A correlation analysis of the signatures is carried out in relation to statistical models in order to determine the material type of the article.

摘要： The present invention relates to an adjustable interference filter, especially for use in gas detection with infrared light within a chosen range, comprising at least two essentially parallel reflective surfaces separated by a chosen distance defining a cavity delimited by the reflective surfaces between which the light may oscillate, and at least one of said surfaces being semitransparent for transmission of light to or from the cavity. The filter comprises a transparent material with a chosen thickness and having a high refractive index positioned in the cavity, and adjustable separation means for adjusting the cavity length between the reflecting surfaces, so as to obtain a cavity constituted by the transparent, high refractive index material and a an adjustable part.

摘要： This invention relates to an interference filter, especially for use in gas detection with infrared light within a chosen range, comprising at least two essentially parallel and partially reflective surfaces with a chosen distance between them thus defining a cavity delimited by the reflecting surfaces between which the light may oscillate, and wherein at least one of said surfaces is partially transparent for transmission of light to or from said cavity. The filter comprises a first transparent material having a high refractive index, e.g. silicon, positioned in at least a part of said cavity, and at least one of said reflective surfaces being divided into a three dimensional pattern with varying shift relative to its plane, thus to provide a position dependent resonance condition between them for separation of different wavelengths in the light.
