The primary source of infrared radiation is heat — the radiation produced by the thermal motion of charged particles in matter, including the motion of the atoms and molecules in an object. The higher the temperature of an object, the more its atoms and molecules vibrate, rotate, twist through their vibrational modes, the more infrared radiation they radiate. Because infrared detectors can be “blinded” by their own heat, high-quality infrared sensing and imaging devices are usually cooled down, sometimes to just a few degrees above absolute zero.

The Optical Society (OSA) presents the 2016 Latin America Optics and Photonics Conference (LAOP), an international congress hosted by The Optical Society, with the primary objective of promoting optics and photonics related activities within the Latin American region. The conference includes a comprehensive technical program and features recognized experts in the fields of optics and photonics.

The brain is the most temperature-sensitive organ in the body. Even small deviations in brain temperature are capable of producing profound effects—including behavioral changes, cell toxicity, and neuronal cell death. The problem faced by researchers and clinicians is how to measure and understand these changes in the brain and how they are influenced by complex biochemical and physiological pathways that may be altered by disease, brain injury or drug abuse.

Today’s high-speed wired communication networks use lasers to carry information through optical fibers, but wireless networks are currently based on radiofrequencies or microwaves. In an advance that could one day make light-based wireless communications ubiquitous, researchers from Facebook Inc.’s Connectivity Lab have demonstrated a conceptually new approach for detecting optical communication signals traveling through the air.

Organic compounds in wastewater, such as dyes and pigments in industry effluents, are toxic or have lethal effect on aquatic living and humans. Increasing evidence has shown that the organic contaminants discharged from electroplating, textile production, cosmetics, pharmaceuticals are the main reasons for the higher morbidity rates of kidney, liver, and bladder cancers, etc. Organic contaminants, especially methyl blue and methyl orange, are stable to light, heat or oxidizing agents and very difficult to remove by conventional chemical or biological wastewater treatment techniques.
