Estimating volume turbulence from light-fields

Abstract

We report on our progress in using light-fields of a distant, static object, observed through distributed volume turbulence to recover an estimate of the turbulence phase at discrete intervals along the path. Our approach is similar to those used by phase diversity and multi-conjugate adaptive optics but instead uses imagery from a single light field frame. Similar to those approaches ours provides a joint estimate of both the scene and the turbulence volume. We present results featuring multiple scenes, integrated turbulence strengths, and isoplanatic angles. Light field sampling effects are also considered.
