Forensic Investigations Using Thermography And Steam
By FLIR Systems, Inc

Investigators constantly are searching for solutions to find concrete blood evidence in less-than-ideal circumstances. This is especially important when working with fabrics carrying diluted blood stains, which could easily be affected by the common practice of adding liquid luminol. Chemistry researchers at the University of South Carolina are investigating an alternative method for detecting and recording evidence of biological fluids.

The Relationship Between Pixel Size And Sensitivity

PCO-TECH looks to debunk the myth that “large-pixel image sensors are always more sensitive than small-pixel sensors.” This article describes, in detail, the relationship between an image sensor’s pixel size and its sensitivity, and how each defines the quality of an image.

Interference Microscopy For Surface Structure Analysis

Interference microscopy encompasses a wide range of techniques when it comes to measuring the many aspects of surface structures. This article discusses the principles of interferometric dimensional metrology applied to surface features best viewed in a microscope.

Raman Spectroscopy Of Pigmented Human Tissue In The Shortwave Infrared

The researchers at Erasmus MC University Medical Center in the Netherlands have developed a method of Raman spectroscopy that will further accelerate the diagnosis of melanoma. This application note discusses how technology developed by Xenics assists this research.

How Ultra-Thin Glass Fibers Help Doctors Spot Ailments And Save Lives
