TL;DR: In this article, the feasibility of using low-order adaptive optics by applying phase-only corrections over horizontal propagation paths is investigated, and a Shack-Hartmann wave-front sensor was built and data were gathered on paths 1 m and 2.5 km.

TL;DR: In this paper, a hand-supportable planar laser illumination and imaging (PLIIM) based device with a light transmission aperture is presented, where a linear image formation and detection (IFD) module is mounted within the housing, and a linear array of image detection elements and also image formation optics with a field of view (FOV).

TL;DR: In this paper, a free-space adaptive optical laser communication system has been proposed, where wavefront sensing and wavefront correction mechanisms are employed along signal transmission and reception channels of all terminals in the communication system (i.e. adaptive optics) to improve the condition of the laser beam at the receiver.

TL;DR: In this article, a wavefront sensing and compensating system for detecting and correcting for distortion in light wavefronts is described in which the wavefront is divided into a plurality of sub-apertures and light intensified and imaged as spots of light from each subaperture onto a detector array.
