• Wavefront — In optics and physics, a wavefront is the locus (a line, or, in a wave propagating in 3 dimensions, a surface) of points having the same phase. Since infrared, optical, x ray and gamma ray frequencies are so high, the temporal component of… …   Wikipedia

• Wavefront coding — In optics, wavefront coding is a method for increasing the depth of field in an image to produce sharper images. It works by blurring the image using a specially shaped waveplate so that the image is out of focus by a constant amount. Digital… …   Wikipedia
