Abstract
A dosimetry probe for monitoring light irradiation dosages and for providing irradiance measurements to monitor the application of light during a phototherapy procedure. The dosimetry probe includes a light delivery optical fiber operable to transmit optical radiation to target tissue and a plurality of dosimetry optical fibers substantially coextensive with the light delivery optical fiber, the distal ends of each of the dosimetry optical fibers arranged at a different axial distance from the light delivery optical fiber to provide irradiance measurements at a number of different axial distances. The dosimetry probe may include a safety feedback optical fiber to monitor the intensity of the treatment light independent of the influence of the optical properties of the target tissue. The dosimetry probe may also include a source dosimetry optical fiber for carrying a modulated dosimetry light signal, which can be selectively detected by means of frequency lock-in technology.
