Widening the angle of view in wavefront coding
説明
The cubic phase mask is known to cause significant changes of point spread function (PSF) as the angle of view increases. view. Instead of the conventional on-axis PSF in the best focal plane, we utilized the arithmetic-average of PSFs at various angles of view to generate the deconvolution filter for wavefront coding, and confirmed that the effective angle of view was successfully expanded about 1.6 times than conventional.
