Abstract
A phase distortion device/method has been developed to improve images. A wave source generates waves, which stimulate the reflection and/or emission of narrow-band waves from an object of interest or a nearby object. The phase distortion of the narrow-band waves is used to obtain an impulse response function, which is then used to correct an image formed by illumination waves.
