Abstract/Summary Hopping between potentials in optical tweezers yields a treasure trove of information. Here we use video and photodiode measurements coupled with a detailed theoretical picture of the optical potential to observe the properties of Brownian motion versus the scaling of trapping parameters. We show that this can be treated as a method of determining fluid and local environmental properties without requiring excessively precise measurements of particle parameters.
