Abstract: A method and apparatus are provided that interrogate, receive, and analyze full emission spectra for at least one fluorescence excitation wavelength and for at least one reflectance measurement to determine tissue characteristics and correlate same to photographic images. Further, the system and method accomplish this measurement rapidly by increasing the light throughput by integrating optics into a hand held unit and avoiding the need for a coherent fiber optic bundle being used. The method includes illuminating a first portion of a target tissue with optical energy, forming a first image of the target tissue, illuminating a second portion of the target tissue with optical energy, performing spectroscopic measurements on optical energy reflected and/or emitted by the target tissue upon illumination of the second portion of the target tissue with optical energy, and determining tissue characteristics of the target tissue based on the results of the spectroscopic measurements.

Abstract: A spectroscopy system is provided which is optimized for operation in the VUV region and capable of performing well in the DUV-NIR region. Additionally, the system incorporates an optical module which presents selectable sources and detectors optimized for use in the VUV and DUV-NIR. As well, the optical module provides common delivery and collection optics to enable measurements in both spectral regions to be collected using similar spot properties. The module also provides a means of quickly referencing measured data so as to ensure that highly repeatable results are achieved. The module further provides a controlled environment between the VUV source, sample chamber and VUV detector which acts to limit in a repeatable manner the absorption of VUV photons. The use of broad band data sets which encompass VUV wavelengths, in addition to the DUV-NIR wavelengths enables a greater variety of materials to be meaningfully characterized. Array based detection instrumentation may be exploited to permit the simultaneous collection of larger wavelength regions.

Abstract: A radiation pulse, such as from a solar simulator, is spectrally analyzed over a selected sampling pulse that is shorter in duration than the radiation pulse and is timed to begin after the start of the radiation pulse. A deformable membrane mirror is controlled to function as a high speed shutter in the path of the radiation pulse. When not deformed, the mirror reflects the radiation pulse into an optical instrument, such as a spectroradiometer. A sampling pulse is generated for a selected time after the start of the radiation pulse and is applied to the mirror to ensure total reflection of the radiation pulse only for the duration of the sampling pulse. Controls are provided to adjust the start time and duration of the sampling pulse, and to adjust the sensitivity of sensing the start of the radiation pulse.

Abstract: A system and method for controlling the light source of a cavity ring-down spectrometer (CRDS). The system comprises a resonant optical cavity having at least two high reflectivity mirrors; a source for providing a continuous wave optical signal into the optical cavity, the source comprising an electrically pumped semiconductor gain medium; and a SOA interposed between the optical signal source and the optical cavity. The SOA receives the optical signal and transmits it to the resonant optical cavity. The system also includes a first detector for monitoring the intensity of radiation emitted from said cavity and generating a first detection signal based thereon; and at least a first controller for deactivating the optical signal based on a comparison of the first detection signal and a predetermined threshold and for thereafter reactivating the optical signal after a delay period in excess of the ring-down time of the optical cavity, the deactivating and reactivating being achieved by respectively turning off and then turning on electrical current to the SOA.
