3. The Supercontinuum Laser Source: Fundamentals with Updated References (Book)

   Explore Article Springer US (Jun 27 2009) Broadband Sources , Textbooks

   Photonics and nonlinear optics are important areas of science, engineering and technology. One of the most important ultrafast nonlinear optical processes is the supercontinuum (SC) – the production of intense white light pulses covering: uv, visible, NIR, MIR, and IR. It is produced using ultrashort laser pulses (ps/fs) to produce the ultrabroad band of frequencies. This book covers the fundamental principles and surveys research of current thinkers and experts in ... (Read Full Article)

4. Assessment of Scleral Spur Visibility With Anterior Segment Optical Coherence Tomography

   Explore Article LWW Online (Jun 15 2009) Ophthalmology

   Purpose: To develop a grading system to evaluate the scleral spur visibility and to investigate the association between this and the angle width. Methods: Sixty healthy normal subjects (33 with open angles and 27 with narrow angles on dark room gonioscopy) underwent anterior segment imaging with the Visante OCT (Carl Zeiss Meditec, Dublin, CA). The anterior chamber angles at 12-o' clock hour positions were imaged and analyzed. The scleral spur ... (Read Full Article)

5. Imaging systems and methods to improve backscattering imaging using circular polarization memory

   Explore Article PatFT » Page 1 of 1 (Apr 7 2009) Patents

   An optical technique to improve the imaging of a target inside suspensions of scattering particles includes the illumination of the scattering particles with circularly polarized light. The backscattered light from the host medium preserves the helicity of incident light, while the backscattered light reflected from the target is predominated with light of opposite helicity. Based on the observed helicity difference in the emerging light that originated at the target and ... (Read Full Article)
