Classification: CPC G | IPC G

Claim 13:
14. A method for measuring time-gated Raman spectrum, wherein the method comprises:
generating a pulse of light towards a target, wherein the target will subsequently emit an optical radiation comprising at least a first portion and a second portion;
providing a time delay to the first portion of the emitted optical radiation, wherein the second portion of the emitted optical radiation bypasses the at least one optical delay element;
dispersing the delayed first portion and the second portion of the emitted optical radiation into a dispersed radiation having a plurality of wavelengths, wherein each wavelength of the dispersed radiation is split into an angularly separate direction, and wherein the dispersed radiation of each portion exits the optical spectral disperser with predetermined relative delays; and
receiving each wavelength of the dispersed radiation on a different spatial region thereof, and measuring the light intensity associated with each wavelength of the dispersed radiation;
recording the measured light intensity associated with each wavelength of the dispersed radiation measured by the sensor element to form a time-resolved optical spectrum.
