Metasurface optics for full-color computational imaging (2018, background): “ce non-diffracting beams over a wide range and in conjunction with a lens can generate an elongated focus. Cubic functions are a common choice because of their simplicity and rectangular separability (30). Furthermore, it can be shown via the stationary phase method applied to an ambiguity function ”
The Light Field Camera: Extended Depth of Field, Aliasing, and Superresolution (2012, background): “Other optical designs such as wavefront coding [12] and focal sweep [13] have been proposed that attempt to recover all-focused images via approximately depthinvariant blurs that are easily deconvolved.”
Computer-assisted sperm analysis (CASA): capabilities and potential developments. (2014, methodology): “Development could startwith an integrated camera software chip [53,54] or by modifying and reprogramming today’s detector arrays [55–57].”
What spatial light modulators can do for optical microscopy (2011, background): “For example, it has been shown that special classes of pupil functions, such as cubic phase offsets, allow one to increase the depth of field [43, 44], which provides sharp image details from axially separated positions in the sample volume.”
Image and depth from a conventional camera with a coded aperture (2007, methodology): “Wavefront coding [Cathey and Dowski 1995], deliberately defocuses the light rays using phase plates so that the defocus is the same at all depths, which then allows a single deconvolution to output an image with large depth of focus, but without allowing the simultaneous estimates of depth.”
