Abstract
We report the design of binary-amplitude masks that in conjunction with digital restoration enable mitigation of optical aberrations. Essentially, the design process aims to maintain high modulation-transfer functions by reducing destructive interference of optical-transfer-function phasors. Two optimization techniques are described: so-called contour masks and the use of multiple pixelated masks. In general the resultant modulation-transfer function is 20% of a diffractionlimited imaging system and due to the absence of nulls recorded images can be restored to a high-contrast diffractionlimited image. Example applications are presented for correcting ocular aberrations and for conformal imaging.
