  • Miniaturized multimodal cars endoscope
    Patent number: 8879058
    Abstract: A miniaturized imaging system is provided that operates in multiple modes, including a coherent anti-stokes Raman scattering (CARS) mode. The imaging system includes: a laser delivery subsystem that generates an excitation signal; a scanning mechanism configured to receive the excitation signal from the laser delivery subsystem and direct the excitation signal through an optics subsystem onto a sample, such that the optics subsystem compensates for chromatic aberration in the excitation signal; and a dichroic mirror that receives emission from the sample in a backward direction and directs the emission along a collection path to a detector. The light source for the laser delivery subsystem may be a single femtosecond pulse laser.
