Wavefront distortion (WD) is white noise that usually occurs in video processing. It is caused by the aberrations in the components you are using to display your image. The most common type of wavefront distortion is chromatic aberration (CA), which is caused by the refraction of light through a lens or a filter.

In the past, video processing applications would often introduce unwanted wavefront distortion into their videos due to the limitations of the hardware and software they used. This would lead to an uneven, blurry, and distorted picture. The introduction of Wavefront Distortion (WD) into video processing opened the door for a new era of image quality and consistency.

WD is a technique that corrects for the wavefront distortion that occurs in video processing. It is based on a mathematical model that takes into account the wavefront distortion caused by lenses, optical or mechanical sensors, and other sources of wavefront distortion. This model can then be used to correct for wavefront distortion in real time, resulting in a more consistent and sharper image.

WD can be applied to a variety of video applications, such as digital cinema cameras, aerial surveillance, automotive safety systems, and virtual reality video. In all these applications, it is important that the video is accurately rendered and reproduced without wavefront distortion. WD provides the tools to correct for these distortions, resulting in a sharper, smoother, and more accurate image quality.

The working principle of WD is relatively straightforward. It begins with the application of a mathematical model to the video data. This model takes into consideration the wavefront distortions that can be caused by various sources, such as lenses, optical or mechanical sensors, and other sources of wavefront distortion. It then calculates the necessary corrections to make the video data appear correct and of high quality.

Once the correction is applied, the video data is then processed using a variety of methods. These methods depend on the video application and can range from simple 2D digital image processing techniques, to more complex 3D image processing techniques. These techniques can then be used to improve the overall image quality and consistency.

WD is a powerful tool for video processing and is used in many industries, including medical, entertainment, advertising, and education. With the introduction of WD into video processing, manufacturers now have the tools to deliver sharper, more consistent, and higher quality images than ever before.
