    Abstract: One embodiment of the present invention provides a system that characterizes a biological sample by analyzing light emissions from the biological sample in response to an excitation. The system first radiates the biological sample with a laser impulse to cause the biological sample to produce a responsive light emission. Next, the system uses a wavelength splitting device to split the responsive light emission into a set of spectral bands of different central wavelengths. The system applies temporal delays to the set of spectral bands so that each spectral band arrives at an optical detector at a different time, thereby allowing the optical detector to temporally resolve the responsive light emission for each spectral band separately. Next, the system captures the delayed spectral bands within a single detection window of the optical detector. The system then processes the captured spectral bands.

    Abstract: A new architecture for implementing a time-resolved Raman spectrometer is 2-3 orders of magnitude faster than current systems. In one embodiment, the invention employs a rotating optical switch to time multiplex an input signal through multiple band-pass filters and into a single optical detector which is electrically activated only when the filtered input light pulse is about to impact it.Time-multiplexing the input signal through multiple optical filters and time-sequencing the optical detector enables the device to detect and analyze 2-3 orders of magnitude faster than current designs. In one embodiment, the system may be employed for the diagnostics of a pathological condition of skin tissue in patients, such as malignant melanoma or other types of skin cancers and abnormal conditions.

    Abstract: Apparatus for registering the spectral signature of a dynamic source event include an imaging-sensor array configured to register electromagnetic energy over a predetermined range of electromagnetic wavelengths and an optical system configured for imaging onto the imaging-sensor array a dispersion pattern of electromagnetic energy emitted from a source event external to the optical system. The optical system includes (i) a focusing element and (ii) a selected set of optical dispersion apparatus. Among the optical dispersion apparatus are at least a first optically dispersive element that disperses a first selected set of wavelengths within the sensitivity range of the imaging-sensor array and at least a second optically dispersive element that disperses a second selected set of wavelengths within the sensitivity range of the imaging-sensor array such that wavelengths emitted from a source event that are within the first and second selected sets of wavelengths impinge simultaneously upon the imaging-sensor array along, respectively, a first extrapolated axis and a second extrapolated axis that is non-parallel to the first extrapolated axis.

    Abstract: A new architecture for implementing a time-resolved Raman spectrometer is 2-3 orders of magnitude faster than current systems. The system additionally is compact, environmentally rugged, low cost and can detect multiple components of a sample simultaneously. In one embodiment, the invention employs a rotating optical switch to time multiplex an input signal through multiple bandpass filters and into a single optical detector which is electrically activated only when the filtered input light pulse is about to impact it.The combination of time-multiplexing the input signal through multiple optical filters and time-sequencing the optical detector enables the device to detect and analyze 2-3 orders of magnitude faster than current designs, processing spectra within milliseconds instead of seconds. The system can process multiple material samples (25+) simultaneously, instead of sequentially, and its mechanical ruggedness and simplicity enables using the system in harsh physical environments when traditional spectrometers can not be used reliably.
