Abstract
Manipulation and management of fiber optic light at the optical fiber level. Use of beam steering techniques on optical fibers that are part of fiber optic probes results in an improved fiber optic probe assembly for low light spectrographic analysis that exhibits improved response to subtle light-matter interactions of high analytical importance and reduced sensitivity to otherwise dominant effects. This is accomplished by adjusting the illumination and collection fields of view in order to optimize the probe's sensitivity. Light manipulation is applied at the optical fiber level so that the probe's delivery pattern and field of view do not require external manipulation and are not adversely affected by investigated media. This allows the light delivery pattern or field of view or both to be aggressively steered off-axis to achieve significantly increased performance levels. Aggressive beam steering is accomplished by employing internally reflective surfaces in the fiber. A reflective metal coating or low refractive index coatings or encapsulants can be used to facilitate internal reflection.
