“…Because of this strong relationship between shear layers and system performance, the aerooptical effects associated with free-shear layers have been of interest to researchers for years [23,24,[66][67][68][69][70][71][72][73]. Investigation into the aero-optical properties of shear layers, specifically as they relate to beam directors, began in the 1970s with the ALL program.…”

This paper serves as Part II of a two-part tutorial on ``aero-optical effects.'' In Part I, we provide introductory material with an emphasis on system-level considerations, particularly for those who are new to the field of aero-optics. In Part II, we move on to survey several sources of aberrations. For example, we cover foundational sources like boundary layers and shear layers, as well as miscellaneous sources like mechanical contamination, shock waves, and aero acoustics. Throughout Part II, we emphasize drivers for system-level performance, which appropriately builds on the system-level considerations covered in Part I. This emphasis will inform future efforts looking to develop airborne-laser systems flying at subsonic, supersonic, and hypersonic speeds.

“…However, the properties of sapphire are limited by the quality and manufacturing technique [8,9]. Meanwhile, the dome is heated by the atmosphere around whose temperature increases due to the thermal radiation, while part of the thermal radiation is accepted by the infrared sensor which results in a radiated interference [10,11]. The thermal radiation of the dome increases with the increase of the temperature, which produces a sharp increase in background radiance and reduces the detection capability and the traceability of detectors.…”
