I describe new wave optics results in cosmological lensing of compact sources, including FRBs and gravitational waves. The wave regime opens up a new window of precision measurement, and requires Picard-Lefschetz theory to compute and interpret the resulting Kirchoff Path Integrals. These results include microlensing mass measurements, planet and dark matter detection, gravitational and plasma lensing, imaginary images, and the possibility of direct measurement of cosmic acceleration utilizing interference effects.
