Infrared Counter-Countermeasure Efficient Techniques using Neural Network, Fuzzy System and Kalman Filter

This paper presents design and implementation of three new Infrared Counter-Countermeasure (IRCCM) efficient methods using Neural Network (NN), Fuzzy System (FS), and Kalman Filter (KF). The proposed algorithms estimate tracking error or correction signal when jamming occurs. An experimental test setup is designed and implemented for performance evaluation of the proposed methods. The methods v...

Numerical Simulation of Infrared Laser Probing Techniques

Exploiting the dependence of the refractive index on carrier concentration and temperature, various infrared laser probing techniques enable the experimental analysis of the carrier and heat flow distributions in the interior of semiconductor devices. In this work we present a complete numerical simulation sequence for the whole measurement process. It includes the electrothermal device simulat...

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.

Infrared Optical Property Measurement Techniques : Definition and Preliminary Design

Improved Infrared Face Identification Performance Using Nonuniformity Correction Techniques

In this paper, the face recognitions rate performance using infrared imagery is improved by adding nonuniformity pre-processing techniques. The infrared spectra contains the heat energy emitted by a face and it naturally present an insensitive behavior to variations in illuminations. Infrared imaging system can be formed by a Focal-PlaneArray technology, a group of photodetectors located in the...
