‘Exquisitely Engineered’ Human Vision Featured in Optical Engineering
Bellingham, Washington, USA (PRWEB) June 12, 2014 -- A new special section on Human Vision in the current issue of Optical Engineering showcases optics and optical engineering research into new techniques and approaches for the study of human vision and the design of novel imaging systems. Put into practice, these new approaches enable applications such as earlier diagnosis of disease, improved treatment monitoring, and more accurate guidance for treatment and surgery. The journal is published by SPIE, the international society for optics and photonics.
The special section includes 11 papers that describe how optics is used to investigate human vision, how new methods for correcting or enhancing human vision are developed and evaluated, and how models of human vision can be used to design and evaluate other imaging systems.
Several of the articles describe new optical imaging techniques, such as quantitative anterior segment optical coherence tomography that measures 3D biometry of the cornea and the lens in the front of the eye.
“The human visual system is an exquisitely engineered system that can serve as a model and inspiration for the design of many imaging systems,” wrote Eli Peli, Harvard Medical School, in a guest editorial in the special section. “For example, advances in optical sensing and imaging have led to important discoveries about retinal image processing, and optical design tools are necessary for improving vision in patients. While advances in optics are improving our understanding of the human visual system, this understanding has also led to improvements in artificial vision systems, image processing algorithms, visual displays, and even modern optical elements and systems.”
Along with Peli, other guest editors of the special section are Susana Marcos, Institute of Optics, Consejo Superior de Investigaciones Cientificas; Stephen Burns, Indiana University; and Joyce Farrell, Stanford University.
Two articles in the section are open access:
• “Intraocular lens alignment from an en face optical coherence tomography image Purkinje-like method” by Mengchan Sun, et al., Institute of Optics, Consejo Superior de Investigaciones Cientificas, reports on new methods of measurement of intraocular lens alignments, which are typically implanted in patients during cataract surgery.
• “Impact of high power and angle of incidence on prism corrections for visual field loss” by Harvard Medical School’s Jae-Hyun Jung and Eli Peli analyzes and identifies ways to mitigate issues in treatments that prescribe prisms for visual field expansion -- often patients who have had a stroke or traumatic brain injury.
Other papers in the special section include:

Articles are available by subscription or pay-per-view in the SPIE Digital Library. Ronald Driggers, St. Johns Optical Systems, is the journal’s editor-in-chief.
The SPIE Digital Library contains over 400,000 items from SPIE journals, proceedings, and books, with approximately 18,000 new research papers added each year. Abstracts are freely searchable, and an increasing number of journal articles are published with open access.
About SPIE
SPIE is the international society for optics and photonics, a not-for-profit organization founded in 1955 to advance light-based technologies. The Society serves nearly 256,000 constituents from approximately 155 countries, offering conferences, continuing education, books, journals, and a digital library in support of interdisciplinary information exchange, professional networking, and patent precedent. SPIE provided more than $3.2 million in support of education and outreach programs in 2013.
