Spatial frequency projection imaging of coherent anti-Stokes Raman scattering (SPIFI-CARS) (Conference Presentation)

Paper Abstract

Conventional CARS microscopy requires scanning a point focus through the specimen limits imaging speed. We present a spatial frequency projection imaging (SPIFI) method for CARS microscopy to spatially multiplex CARS microscopy. A spinning disk modulator is used to rapidly modulate the Stokes field with a rapidly swept spatially periodic transmission grating. SPIFI-CARS images are obtained by Fourier transforming the single pixel signal. Images of CARS and second harmonic generation from histological slices will be presented. The physics of image formation and the impact of multiplexing on SNR will be discussed. Prospects for scaling to high speed CARS imaging will be discussed.
