摘要： An illumination system for increasing a light signal from an object passing through a reflection cavity. The reflection cavity is disposed between spaced-apart, opposed first and second surfaces disposed on opposite sides of a moving stream of objects. A light collection system is disposed substantially orthogonal to a plane passing through the surfaces and the stream so as to collect light that is scattered from or emitted by the objects as they pass through a field of view disposed between the first and second surfaces. A beam of light from a laser source is directed through the stream of moving objects in a direction nearly orthogonal to the stream (but slightly inclined) and lying in the plane that extends through the surfaces and the stream. Due to the reflection angle and the distance between the stream and the first surface, the point at which the light reflected from the first surface intersects the stream on a second pass is displaced from where it passed though the stream on its initial pass. The light is reflected back and forth between the surfaces a plurality of times, illuminating a different portion of the field of view with each pass until, having ranged over the field of view, the light exits the reflection cavity. The “recycling” of the light beam in this manner substantially improves the SNR of the detection system by increasing an average illumination intensity experienced by the objects in the stream.

摘要： An illumination system for increasing a light signal from an object passing through a reflection cavity. The reflection cavity is defined by spaced-apart, opposed first and second surfaces disposed on opposite sides of a central volume. Preferably the first reflecting surface forms an acute angle with the second reflecting surface. A beam of light is directed into the reflection cavity so that light is reflected back and forth between the first and second surfaces a plurality of times, illuminating a different portion of the central volume with each pass until, having ranged over the central volume, the light exits the reflection cavity. The “recycling” of the light beam in this manner substantially improves the signal to noise ratio of a detection system used in conjunction with the reflection cavity by increasing an average illumination intensity in the central volume.
