摘要： Particle detection systems without knowledge of a location and velocity of a particle passing through a volume of space, are less efficient than if knowledge of the particle location is known. An embodiment of a particle position detection system capable of determining an exact location of a particle in a fluid stream is discussed. The detection system may employ a patterned illuminating beam, such that once a particle passes through the various portions of the patterned illuminating beam, a light scattering is produced. The light scattering defines a temporal profile that contains measurement information indicative of an exact particle location. However, knowledge of the exact particle location has several advantages. These advantages include correction of systematic particle measurement errors due to variability of the particle position within the sample volume, targeting of particles based on position, capture of particles based on position, reduced system energy consumption and reduced system complexity.

摘要： A particle detection system that images and detects particles in a fluid flow stream through use of detector array(s) is described. The detection system may include light source arrays that may selectively illuminate a particle in a fluid stream. The detection system may also include a detector array employing smart binning to read the measured signals. The smart binning of the detector array may be achieved through knowledge of an exact particle location provided by a position sensitive detector. The detector array(s) may be low cost based on intelligence built into the system. This particle detection system may be particularly useful for detection and discrimination of different particle types since the read-out of the particle signals can be accomplished with low noise and can be flexible enough to optimize the read out measurements for each particle. The particle detection system may be used, for example, in early warning contamination detection systems and manufacturing processes.

摘要： Biological aerosols are detected in real time by passing air, which may contain the aerosols, through a duct having a pair of photodetectors adjacent the duct for detecting fluorescence of the aerosols produced by ultraviolet laser beam illumination of the airflow. A pair of opposed mirrors, make the effective sample air volume large, by producing multiple ultra-violet beam illumination paths through adjacent portions of the duct for each single pulsed beam, in turn increasing the magnitude of the detected fluorescence signal.

摘要： A parametric generator for efficiently converting short duration pump pulses of a first frequency to a signal beam of a desired frequency is described. The parametric generator includes a second order nonlinear parametric medium, a retro-reflector, and an optical re-imaging system. Each optical sub-path through the parametric medium is substantially distinct and non-overlapping. At least two optical sub-paths have a direction within a phase matching acceptance angle of the parametric material which corresponds to the desired wavelength. The parametric generator can be configured to be compact because it utilizes multiple transmissions through the parametric medium and it employs only a single pump beam input.
