    Abstract: 本发明公开一种用于表面缺陷检测的线性光源装置及系统,该装置包括线性光源;线性光源由数个照明光源组成,照明光源呈一字型排列,相邻的两个照明光源的距离相等;沿线性光源的光线照射方向,装置依次设有准直透镜和会聚透镜,会聚透镜与准直透镜平行,准直透镜的数量与照明光源的数量相同,每个照明光源位于对应的准直透镜的焦点。本发明先将照明光源的发射光线在X轴和Y轴方向进行准直整形,将光线整形为具有较小的发散角度的准平行光,防止光线从不同角度相互补光,再进行会聚整形,使光线会聚至相机的镜头处,进而使获取的检测图像中缺陷区域与其他区域的明暗区别明显,提高检测的准确性。

    Abstract: An atomic absorption spectrophotometer for simultaneously measuring a plurality of elements different in kind from each other. A cylindrical heating furnace is provided for heating a sample being analyzed to dry, ash and atomize the sample thereby producing atomic vapor. A plurality of hollow-cathode discharge tubes corresponding in number to the elements being detected are arranged for simultaneously emitting light beams respectively containing line spectra of the respective elements, to cause the light beams to be incident upon the heating furnace at respective angles of inclination with respect to a central axis of the heating furnace. A plurality of spectral detection systems are arranged behind the heating furnace in relation to the angles of inclination, for respectively spectral-diffracting and receiving the light beams having their respective line spectra absorbed by the atomic vapor. A signal processing device is provided for carrying out calculation to obtain concentrations or quantities of the respective elements in the sample being analyzed, on the basis of respective ratios of atomic resonance absorption of the respective line spectra spectral-detected.

    Abstract: An infrared monitor for measuring the presence of at least one gas phase molecular species including a sample path for containing a sample to be monitored for the molecular species. A sample beam of infrared source emission of the molecular species to be monitored for passage through the sample path is provided to the sample path. The sample beam includes at least one primary spectral emission line which is significantly absorbed by the molecular species. The decrease in the intensity of the at least one primary infrared source spectral emission line passing through the sample path is detected as a function of the absorption of the at least one line by the molecular species present in the sample.
