ABSTRACT:
An apparatus and method for detecting particles. A flow tube is surrounded by eight off-axis ellipsoidal mirrors all having a common first focus coincident with a portion of the flow tube and each having a distinct second focus. In one embodiment, sources of radiation are arranged coincident with exit ports in the mirrors that are also coincident with the respective distinct second foci. These radiation sources are momentarily energized in sequence (or simultaneously), causing light to illuminate a corresponding ellipsoidal mirror. This light strikes the common first focus within a portion of the flow tube. Any particles within the first focus will then scatter the light, and depending upon the source wavelength and the particle, may also provide some amount of fluorescence. This energy is captured by detectors and analyzed to determine the type, size and quantity of particles at the first focus.
