Imaging through Atmospheric Turbulence

Overview

Imaging through atmospheric turbulence is a fundamental problem for long-range imaging systems. Purdue i2Lab has specialities in several aspects of the subject:

  • Wave optics theory

  • Turbulence simulators

  • Forward imaging models that can be used for deep neural networks

  • Image reconstruction algorithms

  • Object recognition
