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.

Detectability of Occultations of Stars by Objects in the Kuiper Belt and Oort Cloud
The serendipitous detection of stellar occultations by outer solar system objects is a powerful method for ascertaining the small end (r 15 km) of the size distribution of Kuiper Belt objects and may

We explore the possibility of detecting small Kuiper belt objects (KBO) by serendipitous observation of stellar occultations: We show that such unpredictable occultations may allow us to detect a
Measuring the Abundance of Sub-kilometer-sized Kuiper Belt Objects Using Stellar Occultations
We present here the analysis of about 19,500 new star hours of low ecliptic latitude observations (|b| ≤ 20°) obtained by the Hubble Space Telescope's Fine Guidance Sensors over a time span of more
A single sub-kilometre Kuiper belt object from a stellar occultation in archival data
An analysis of archival data reveals an occultation by a body with an approximately 500-metre radius at a distance of 45 astronomical units that implies that sub-kilometre-sized Kuiper belt objects are undergoing collisional erosion, just like debris disks observed around other stars.
An Observational Upper Limit on the Interstellar Number Density of Asteroids and Comets
