1. A tissue spectroscopy device for use with an interventional device, comprising:
- a spectrometer module including;
a light source having a distal facing, light-emitting output end;
a plurality of light detectors arranged distally of the light source, wherein an output end face of each of the plurality of light detectors is arranged along an axis transverse to a longitudinal axis of the spectrometer module; and
an optically non-linear member positioned distally of the light source and configured to amplify a frequency of light emitted from the output end;
wherein the spectrometer module is selectively detachable from the interventional device during operation.

Abstract
A miniaturized spectrometer is adapted for placement within a body near tissue to be characterized. The spectrometer includes a light source and a plurality of light detectors. The light source generates light to illuminate the tissue. The detectors detect optical signals from the illuminated tissue and convert these optical signals to electrical signals. The miniaturized spectrometer can be disposed at the distal end of an interventional device. Optical conduits, such as fiber optic cables or strands, extending the length of the interventional device are not required when the miniature spectrometer is employed.
