    • A detector for optically detecting biological aerosols in a sample volume using non-imaging optical components (NIOCs) includes a light source configured to stimulate bio-fluorescence of tryptophan or nicotinamide adenine dinucleotide. A first NIOC is disposed adjacent to the light source and is configured to direct light away from the first light source. A detector is configured to detect bio-fluorescence associated with biological aerosols, and a second NIOC is disposed adjacent to the detector and is configured to direct light toward the first detector. In at least one embodiment, each NIOC comprises a compound parabolic collector. In one embodiment, the volume is disposed between the first and second NIOC, and in other embodiments, the volume is disposed distally of both NIOCs. To facilitate volume production, the NIOC can be formed as an integral structure. Preferably, the sample is a volume of a gaseous fluid, such as air.
    • 使用非成像光学部件(NIOC)光学检测样品体积中的生物气溶胶的检测器包括被配置为刺激色氨酸或烟酰胺腺嘌呤二核苷酸的生物荧光的光源。 第一NIOC设置成与光源相邻,并且被配置为将光引导离开第一光源。 检测器被配置为检测与生物气溶胶相关联的生物荧光,并且第二NIOC被设置为与检测器相邻,并且被配置为将光引向第一检测器。 在至少一个实施方案中,每个NIOC包括复合抛物线收集器。 在一个实施例中,体积设置在第一和第二NIOC之间,并且在其他实施例中,体积被放置在两个NIOC的远端。 为了促进批量生产,NIOC可以形成为一体的结构。 优选地,样品是气体流体的体积,例如空气。
