Abstract
A scanning tunable detection system and related method for analyzing samples includes a source of time varying excitation signals and a tunable optical filter for selectively transmitting time-varying optical signals emanated from a sample following irradiation with the time varying excitation signals. A detector is provided for converting the time-varying optical signals to electrical detection signals. The system can identify components in a sample using phase sensitive or time sensitive detection. A slew scan mode can be used to permit slow scanning through spectral regions rich in information but quickly in regions without such information.
Claims26
A scanning tunable detection system for analyzing a sample, comprising:
- a source of time varying excitation signals;
- a tunable optical filter for selectively transmitting time-varying optical signals emanated from said sample following irradiation with said time varying excitation signals, and
- a detector for converting said time-varying optical signals to electrical detection signals.
A method for identifying at least one component in a sample, comprising the steps of:
- providing a source of time-varying radiation;
- irradiating said sample with said time-varying radiation, wherein a time-varying optical signal emanates from said sample;
- converting said time-varying optical signals to electrical detection signals, and
- processing said electrical detection signals to provide time-varying measurements relating to said sample.
