Ecological restoration is an increasingly important tool for managing and improving highly degraded or altered environments. Faced with a large number of sites or ecosystems to restore, and a diverse array of restoration approaches, investments in ec

The speckle size metric known as power-averaged speckle size (PASS), which is based on the integral of the power spectral density of the data, is insensitive to target asymmetry. PASS is defined as the inverse of the median frequency of the power spe

Robust reconstruction of coherent speckle images from non- imaged laser speckle patterns in the aperture plane of an optical system requires adequate sampling of the speckle intensity at the focal plane. Although detector size cannot be changed dynam

This paper describes the use of an auto-correlation technique to determine the minimum speckle size of a speckle pattern collected by a focal plane array of pixels. Object support for initialization of speckle image processing algorithms, as well as

In classical imaging, the optical transfer function (OTF) conveys information about how well the optical system transmits individual spatial frequencies of the object. This OTF is based on the point spread function of the system; that is, the ability

The imaging of a moving target by a typical CCD or CID camera with a finite integration time and finite-sized detectors presents a challenging problem in modeling and analysis. This problem is further complicated if the target is illuminated with a p

The recovered object in sheared beam imaging is an accumulated average of instantaneous "speckled" image frames. Atmospheric perturbations cause a random tilt in the phase of the return speckle pattern. This tilt induces a random translation in each

In sheared beam imaging, a target is coherently illuminated with three sheared and modulated beams. Both target motion and the temporal distribution of the laser illumination affect image recovery. Movement of the target will cause a corresponding mo
