Optical Heterodyning - Focus Correction

Engineers at Mitsubishi Electric have announced that they developed a special coded aperture that refocuses an image after it’s been taken. In the system which is called a “heterodyne light field camera,” the depth of field is increased by as much as 10 times. This is a vast improvement over the handheld plenoptic camera concept that refocuses an image after its capture using software, but which produced an image so reduced is resolution that it lost any real benefit.

Optical Looks promising but also has shortfalls, please visit Refocus Photos for more info on the project and also Deblurring Flutter Shutter Camera on another interesting development from the same team.
