巴林格(BARRINGER)公司的莱塞荧光探测器(LF)使用紫外氮激光检测荧光物质的痕迹总量。一窄的光束从接收器的光学器件同轴发射,从靶上收集荧光。荧光的返回信号,波长大于激光波长的通过距离选通光谱分析器进行检测,用反向散射的辐射脉冲同步,定时选通该检测器使背景减弱。在整个白天可以工作。发射光谱的分布及检测时荧光光谱强度的分布用来鉴别出现在靶上的荧光物质的类型和总量。发射物的光谱信息用16道柱状图描绘,当测量时信息是由两个宽的光谱带的余辉时间值表示。在白天机载操作的高度是一千英尺,晚上是二千英尺。
BARRINGER’s Leicester Fluorescence Detector (LF) uses UV-A laser to detect the total amount of fluorescent material traces. A narrow beam of light is emitted coaxially from the optics of the receiver to collect fluorescence from the target. Fluorescent return signals, wavelengths longer than the wavelength of the laser, are detected by a distance gated spectrometer, synchronized with backscattered radiation pulses, and periodically gated to attenuate the background. Can work throughout the day. The distribution of the emission spectrum and the distribution of the fluorescence intensity at the time of detection are used to identify the type and amount of the fluorescent substance present on the target. The spectral information of the projectile is depicted by a 16-bar histogram, with the information being expressed as the afterglow time value of two broad spectral bands when measuring. The height of airborne operations during the day is one thousand feet and at night two thousand feet.
