Detecting Interstellar Objects Through Stellar Occultations

Stellar occultations have been used to search for Kuiper Belt and Oort Cloud objects. We propose a search for interstellar objects based on the characteristic durations ($\sim 0.1 \mathrm{s}$) of their stellar occultation signals and high inclination relative to the ecliptic plane. An all-sky monitoring program of all $\sim 7 \times 10^6$ stars with $R \lesssim 12.5$ using 1-m telescopes with $0.1 \; \mathrm{s}$ cadences is predicted to discover $\sim 1$ interstellar object per year.
