    • The invention relates to a device (1) suitable for controlling a surface (8) of an object (7), notably with respect to raised areas on said surface (8). The device (1) comprises a light source (2, 3) for generating a light beam (5, 6) directed towards the surface as well as a light sensor (4) for detecting light scattered by a raised area on the surface (8). The light beam (5, 6) generated by the light source (2, 3) is configured so as to scan the surface (8) in such a way that the raised area on the surface scatters the light beam (5, 6). If there is no raised area the light beam (5, 6) undergoes ideally no, or else only slight, changes. The light sensor (4) is arranged in such a way that at least part of the scattered light can be detected. In this manner it is possible to detect, for example, impurities on uneven or structured surfaces.
    • 本发明涉及适于控制物体(7)的表面(8)的装置(1),特别是相对于所述表面(8)上的凸起区域。 装置(1)包括用于产生朝向表面的光束(5,6)的光源(2,3)以及用于检测由表面上的凸起区域散射的光(8)的光传感器(4) )。 由光源(2,3)产生的光束(5,6)被构造成以使得表面上的凸起区域散射光束(5,6)的方式扫描表面(8)。 如果没有凸起区域,则光束(5,6)理想地经历没有,或者仅稍微改变。 光传感器(4)以能够检测散射光的至少一部分的方式配置。 以这种方式,可以检测例如在不均匀或结构化表面上的杂质。

    • The invention relates to a method and a device for quantitative and qualitative on-line differentiation of biotic and abiotic particles. The methods and devices are used to ensure quality and to monitor production as well as in analysis procedures for particular contamination's of gaseous media. The methods and devices are chiefly used in pharmacology, food technology, medicine, biotechnology and health care and in controlling maximum admissible concentration values. According to the inventive method, the gas sample to be measured is briefly heated at very high temperatures in a heating chamber (3). Dimensional distribution of particle contamination is determined before and after heating by means of diffuse light sensors (1, 2). Dimensional changes of biotic panicles caused by heating make it possible to determine their proportion in total particle load of the gas sample and their composition.
    • 本发明涉及用于生物和非生物颗粒的定量和定性在线分化的方法和装置。 这些方法和设备用于确保质量和监测生产以及特定污染气体介质的分析程序。 方法和装置主要用于药理学,食品技术,医药,生物技术和医疗保健以及控制最大允许浓度值。 根据本发明的方法,待加热的气体样品在加热室(3)中在非常高的温度下短暂加热。 通过漫射光传感器(1,2)在加热之前和之后确定颗粒污染物的尺寸分布。 通过加热引起的生物穗的尺寸变化使得可以确定它们在气体样品的总颗粒载荷中的比例及其组成。
