An optical resonance imaging system includes a light emitting device to emit laser pulses onto a subject. The laser pulses include a first pulse and a second pulse to place the subject in an excited state. The laser pulses also include a third pulse to stimulate emission of one or more third order signals from the subject. The system also includes a spectrometer to receive the one or more third order signals and to generate spectrum signals commensurate with intensities of the one or more third order signals. The system may further include circuitry configured to analyze the spectrum signals, generate one or more images of the subject based on the analysis, and construct one or more maps of positions of the subject based on the one or more images.

Systems and methods for optical resonance imaging

A technique for forming a two-dimensional electronic spectrum of a sample includes illuminating a line within a portion of the sample with four laser pulses; where along the entire line the difference in the arrival times between two of the laser pulses varies as a function of the position and the difference in the arrival times between the other two pulses is constant along the entire line. A spectroscopic analysis may then be performed on the resulting pulsed output signal from the illuminated line to produce a single-shot two dimensional electronic spectroscopy.
