Techniques for Enhancing DOF in Image Processing

Several techniques have been employed to enhance the depth of field in image processing. These include the use of shaded apertures, depth-scanning microscopes, coded gratings, and annular apertures with optical equalization.

Shaded apertures improve the coherent optical transfer function, thereby increasing the depth of field.

Depth-scanning microscopes utilise an aluminised membrane to produce a varifocal mirror effect.

Coded gratings, combined with a selective mask in the spatial spectrum plane, optimise the depth of field for transparent specimens.

Another method involves the use of annular apertures, coupled with optical equalization of the modulation transfer function.

These techniques have been critical not only in enhancing the depth of field but also in fostering advancements in high-resolution microscopy.

As such, they represent significant strides in image processing technology.
