Aero-optical effects have received increasing attention in recent decades with the
continuous development of high-speed missiles' imaging guidance systems, airborne laser …

In recent years, the demand for optical imaging and detection in hypersonic aircraft has
been on the rise. The high-temperature and high-pressure compressed flow field near …

Wall-modeled large-eddy simulations of turbulent boundary-layer flows over a flat plate at
Mach 3.5, 7.87, and 13.64 were carried out, and the aero-optical distortions resulting from …

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 …

Compressible wall-modeled large-eddy simulations of Mach 8 turbulent boundary-layer
flows over a flat plate were carried out for the conditions of the hypersonic wind tunnel at …

changes in the refractive index at the high-speed flow over the wedge, using a combination …

Aero-optical distortions arise when light travels through flow fields with varying density,
causing beam distortion proportional to the density fluctuations. These distortions, quantified …

Aero-optics refers to optical distortions due to index-of-refraction gradients that are induced
by aerodynamic density gradients. At hypersonic flow conditions, the bulk velocity is many …
