    • A trace species detection System for engine health monitoring, the system including a laser (32) for generating a laser beam (34), and optics for focusing the laser beam into an exhaust plume of an engine for thereby creating a spark in the exhaust plume. The System further includes spectral analysis instrumentation (40) for detecting light emissions from the spark, and statistical processing instrumentation (100) for analyzing data from the spectral analysis instrumentation (40) for thereby identifying and quantifying specific particles within a volume of the spark. The invention also provides a method of monitoring the health of an engine, the method including generating a laser beam, focusing the laser beam into an exhaust plume of the engine for thereby creating a spark in the exhaust plume, detecting light emissions from the spark, and analyzing data from the detection for thereby identifying and quantifying specific particles within a volume of the spark.

    • There is provided an imaging device comprising a plurality of photodetectors in a predetermined spatial arrangement. Each photodetector is connected to a different predetermined pair of first and second readout channels so that the spatial position of an active photodetector can be determined from the corresponding pair of active readout channels. The number of readout channels is less than the number of photodetectors. For each photodetector its first readout channel is shared with a first plurality of other photodetectors of the arrangement, and its second readout channel is shared with a second plurality of other photodetectors of the arrangement. A first option is that the second plurality is greater than the first plurality for at least some of the photodetectors, with the position of an event occurring at one of the photodetectors being determined from the active first and second readout channels, and with the energy and/or timing of the event being determined from the active firstreadout channel. A second option is that at least some of those photodetectors sharing the same first channel are not adjacent in the arrangement. A third option is that the photodetectors are silicon photomultiplier detectors. The first to third options can be used separately, in isolation, or in any combination.
    • 提供了一种具有预定空间布置的多个光电检测器的成像装置。 每个光电检测器连接到不同的预定的一对第一和第二读出通道,使得可以从相应的一对有源读出通道确定有源光电检测器的空间位置。 读出通道的数量小于光检测器的数量。 对于每个光电检测器,其第一读出通道与该布置的第一多个其它光电检测器共享,并且其第二读出通道与该布置的第二多个其它光电检测器共享。 第一选择是对于至少一些光电检测器,第二多个大于第一多个,其中在一个光电探测器处发生的事件的位置由有源第一和第二读出通道确定,并且与能量和 /或事件的定时由活动的初始通道信道确定。 第二种选择是共享相同第一通道的那些光电探测器中的至少一些在该布置中不相邻。 第三种选择是光电检测器是硅光电倍增管检测器。 第一至第三选项可以单独使用,单独使用,也可以任意组合使用。
