Methods of depth-of-field extending of optical-digital image detectors
In this paper these methods of depth of field extending while imaging are examined: method with applying of cubic-phase mask, method with applying of coded aperture and method with sharpness transportation through color channels. All of these methods can be characterized that specially blurred image been digitized than restored to sharpness image using digital image processing. Blurring is due to modification of already existed lenses and do not needed in moving construction parts. Comparison of proposed methods between themselves is to realized using characteristics that convenient for optical systems estimation.
