Thermal Imaging and Clandestine Surveillance using Low‐Cost Polymers with Long‐Wave Infrared Transparency

Towards longwave infrared tuneable filters for multispectral thermal imaging applications

Many thermal imaging applications stand to gain from the inclusion of multispectral capabilities in the long wave infrared (LWIR). While infrared spectral imaging systems presently exist, the addition of multispectral capabilities will provide a number of advantages, including the ability to accurately quantify the temperature distribution a scene, and the potential for dramatically improved ta...

Human Detection using Infrared Thermal Imaging System

Image processing techniques were used to enhance the recorded thermal images and to remove unwanted noise. The skin surface area centered on the tip of the face was specified by a square that covered the region using Haarlike feature method. The face is detected and then tracked. The camera adjusts its pan and tilt continuously to capture the face at center location of display screen. Experimen...

Longwave infrared compressive hyperspectral imager

Physical Sciences Inc. (PSI) is developing a longwave infrared (LWIR) compressive sensing hyperspectral imager (CS HSI) based on a single pixel architecture for standoff vapor phase plume detection. The sensor employs novel use of a high throughput stationary interferometer and a digital micromirror device (DMD) converted for LWIR operation in place of the traditional cooled LWIR focal plane ar...

Diagnosis of Breast Cancer using a Combination of Genetic Algorithm and Artificial Neural Network in Medical Infrared Thermal Imaging

Introduction This study is an effort to diagnose breast cancer by processing the quantitative and qualitative information obtained from medical infrared imaging. The medical infrared imaging is free from any harmful radiation and it is one of the best advantages of the proposed method. By analyzing this information, the best diagnostic parameters among the available parameters are selected and ...
