Abstract

The unique structure of frequency combs, light sources whose lines are perfectly evenly-spaced, allows for new avenues in the measurement of optical signals. I will discuss our work on frequency comb ptychoscopy, a radiometric technique that allows the spectrum of passive sources to be measured by many comb lines at once.1 Because the heterodyne signals from many signals are folded on top of one another at intermediate frequencies, an inversion algorithm is demonstrated that is able to unravel these beatings. This technique combines the resolution and speed of heterodyne spectroscopy with the bandwidth of comb spectroscopy, and has particular promise in the domain of remote sensing.
