Paper Abstract

For applications involving optical beam propagation through the atmosphere, knowledge of the path extinction can be a critical measurement. Measurement of this parameter has been performed in a variety of ways in the past. These approaches have been effective but require careful calibration and expensive Focal Plane Arrays (FPAs) for imaging. In this work, we describe the development of a Near-Infrared (NIR) imaging device utilizing a single detector element, forming a type of single-pixel camera specialized for extinction measurements. This approach somewhat simplifies the calibration process and avoids the expense of an FPA. We demonstrate the capability of the device to measure path extinction through extended real-world testing.
