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.
