The aberration introduced by the primary optical element of a lightweight large aperture telescope can be corrected with a diffractive optical element called the liquid crystal spatial light modulator. Such aberration is usually very large, which makes the design and modeling of such a system difficult. A method to analyze the system is introduced, and the performance limitation of the system i...

The numerical modeling of field-assisted ion exchange in glass through a finite aperture is carried out. The effects of unequal ion mobilities and thermal diffusion are included we believe for the first time in the 2-D case. This allows for the modeling of optical channel waveguides with graded index profiles. It is demonstrated that annealing of backdiffused channel guides is far superior to b...

The paper describes an approach to the optical transmission network modeling. The modeling process is based on two main assumptions – transmission network carries IP datagrams using layer 2 protocol as a framing technique and Wavelength Division Multiplexing (WDM) is used as a transmission technique on the physical layer. Protection and restoration mechanisms have been implemented on the photon...

A computer program called IMD is described. IMD is used for modeling the optical properties ~reflectance, transmittance, electric-field intensities, etc.! of multilayer films, i.e., films consisting of any number of layers of any thickness. IMD includes a full graphical user interface and affords modeling with up to eight simultaneous independent variables, as well as parameter estimation ~incl...

IEEE Computer Graphics and Applications 11 The Optical Diagnostics and Applications Laboratory (ODALab) is investigating methods and technology for 3D visualization and imaging. Specifically, we’re integrating and assessing systems driven by real-world applications that can benefit from or enhance distributed collaborative environments. Although optics is at the core of the research program, th...

We present a ray-tracing application in the modeling of an optical detection element employed as a sensor of refractive index of surrounding fluids or gases. The detection element is a solid glass microstructure having a surface of the second order. We exploit the sensitivity of internal reflection of light on the element’s surface to the refractive index of the surrounding medium, operation ne...

Objectives: In this article, a new procedure for increasing the light penetration depth in a tissue is studied and simulated. It has been reported that the most important problem in biomedical optical imaging relates to the light penetration depth, and so this makes a dramatic restriction on its applications. In the optical imaging method, the detection of the backscattered pho...
