DIVISION VIII: OPTICAL and INFRARED TECHNIQUES

Polarimetry Techniques at Optical and Infrared Wavelengths

The techniques and components used to measure both linear and circular polarization at wavelengths from 0.3 μm to 20 μm are reviewed. Some emphasis is given to the implementation of polarimetry on the latest generation of large-aperture telescopes and some of the difficulties being encountered are addressed.

Refractive Dual Band Infrared Imager Optical Design

Infrared imagers are important for reorganization and monitoring. This paper discusses the design of an infrared imager. Optical design in medium wavelength infrared (MWIR) and long wavelength infrared (LWIR) bands is different and needs distinct detectors and materials. Reflective systems are not suitable due to their small field of view (FOV) and vignetting. Refractive dual band optical syste...

Emerging Optical CDMA Techniques and Applications

In this paper we present an in-depth review on the trends and the directions taken by the researchers worldwide in Optical Code Division Multiple Access (OCDMA) systems. We highlight those trends and features that are believed to be essential to the successful introduction of various OCDMA techniques in communication systems and data networks in near future. In particular we begin by giving a c...

Infrared Optical Property Measurement Techniques : Definition and Preliminary Design

High-speed All- Optical Time Division Multiplexed Node

In future high-speed self-routing photonic networks based on all-optical time division multiplexing (OTDM) it is highly desirable to carry out packet switching, clock recovery and demultplexing in the optical domain in order to avoid the bottleneck due to the optoelectronics conversion. In this paper we propose a self-routing OTDM node structure composed of an all-optical router and demultiplex...
