- Аннотация: This chapter describes recent results of basic research in the area of fiber array system development with major focus on fiber array architectures, integration of adaptive optics (AO) and beam control capabilities, as well as coherent beam combining and atmospheric compensation techniques with the common goal of the projected beam power density increase at either unresolved (point source) or resolved (extended or speckle) targets. The chapter explains turbulence-induced phase aberration compensation with fiber array-integrated piston and tip—tilt control. The phase conjugate control of the combined beam transmitted by the fiber array was implemented by computing the phase of the target return wave originating from a monochromatic coherent small size light source (beacon) located at the target plane. The chapter concludes with a discussion on practical issues related with the experimental implementation of the target-in-the-loop (TIL) coherent beam combining over tactical-range atmospheric paths.
