Abstract:

At compressible flow speeds, the flow around blunt objects such as optical turrets creates time- and spatially-varying density fields. These inhomogeneous density fields mean that an inhomogeneous index-of-refraction field exists around the optical-turret. As a result, as light traverses through this field, an otherwise collimated wavefront becomes distorted. these distortions reduce the far field irradiance that can be delivered on a target.
