Imagine Techniques for Passive Atmospheric Turbulence Compensation
|
Solid State Scientific Corp (SSSC) develops algorithms for imaging through atmospheric turbulence. SSSC algorithms improve upon one of the traditional techniques for imaging through atmospheric turbulence, the so-called "Lucky Look" technique by applying Fourier analysis to select the sharpest regions from a sequence of collected images.

The images above demonstrate SSSC's turbulence processing for imagery of two buildings in Boston as observed from Pack Monadnock 55 mile to the northwest. The left frame of each illustrates the imagery without turbulence compensation. The center frame of each is the result of turbulence restoration based on 16 frames. The right frame of each has been restored based on 320 frames. Note that the structure in the building is more easily discerned in the processed imagery, and that the processed imagery is free of overshoots that occur with conventional sharpening.
