Advances in single-pixel imaging toward biological applications
In this work, we discuss two new methods for single-pixel imaging. First, we leverage advances in laser metrology and frequency synthesis to measure small shifts in the center frequency of an optical pulse. Pulses acquire such shifts when probing a transient optical susceptibility, as in impulsive stimulated Raman scattering, which we use to demonstrate the technique. We analyze the limits of this technique with regard to fundamental noise, and predict detection sensitivity in these limiting cases. We then present work on imaging in two dimensions, both x-y and x-z, using single element detectors. ...
