Comparing the extended depth-of-field imaging performance of spherical aberration and asymmetric wavefront coding

We compare the image quality between asymmetric wavefront codings and the simpleto-manufacture spherical aberration over an extended focal range. We verify and explain the superior performance of the spherical aberration via simulation results. c © 2009 Optical Society of America OCIS codes: (060.2320) Fiber optics amplifiers and oscillators; (060.4510) Optical communications

Spherical coded imagers: Improving lens speed, depth-of-field, and manufacturing yield through enhanced spherical aberration and compensating image processing

Recently, joint analysis and optimization of both the optical sub-system and the algorithmic capabilities of digital processing have created new digital-optical imaging systems with system-level benefits. We explore a special class of digital-optical imaging systems called spherical coding that combine lens systems having controlled amounts of spherical aberration with digital sharpening filter...

Piezoelectric annular array for large depth of field photoacoustic imaging

A piezoelectric detection system consisting of an annular array is investigated for large depth of field photoacoustic imaging. In comparison to a single ring detection system, X-shaped imaging artifacts are suppressed. Sensitivity and image resolution studies are performed in simulations and in experiments and compared to a simulated spherical detector. In experiment an eight ring detection sy...

Depth-of-Field and Coded Aperture Imaging on XSlit Lens

Recent coded aperture imaging systems have shown great success in scene reconstruction, extended depth-of-field and light field imaging. By far nearly all solutions are built on top of commodity cameras equipped with a single spherical lens. In this paper, we explore coded aperture solutions on a special non-centric lens called the crossedslit (XSlit) lens. An XSlit lens uses a relay of two ort...

Experimental Testing on an Effective Technique to Reconstruct the Far- Field Pattern of a Long Antenna from Near-Field Measurements Acquired via Spherical Spiral Scan

In this paper, the experimental validation of a fast and accurate near-field – far-field (NF–FF) transformation with spherical spiral scanning for elongated antennas is provided. Such a transformation relies on a nonredundant sampling representation of the voltage measured by the probe, obtained by using the unified theory of spiral scans for nonspherical antennas and adopting a cylinder ended ...
