Abstract: A stimulated Raman scattering tomography system includes means for generating a first input light beam, means for generating a second input light beam, an objective, a condenser and a detector. The first input light beam is phase-modulated while the second input light beam is amplitude-modulated. The objective is configured to direct the first and second input light beams onto a sample. The condenser is configured to collect an output light beam from the sample. The is detector configured to detect at least a portion of the output light beam corresponding to the first input light beam. The system further includes means for forming a depth-resolved image of the sample from the detected portion of the output light beam.
