  • Skin Lesions Classification with Optical Spectroscopy
    to assist the dermatologist seems natural. Complicating matters is. a blood cancer called Cutaneous T-Cell Lymphoma, which also exhibits. symptoms as skin lesions. We propose a framework using optical spectroscopy. and a multi-spectral classification scheme using support vector machines to. assist
  • Optical Spectroscopy
    A customer who is completing his doctorate in Chemistry at the California Institute of Technology has identified the need to measure fast optical signals using fast photo-detectors. The signal pulse width is as short as 2ns. Signals will be acquired at a 1KHz repetition rate, with a record length of
  • PC-Based Digitizers Empower Modern Optical Spectroscopy (.pdf_
    Modern optical spectroscopy experiments require intensive use of high-powered computers to collect, analyze, store, and display data. Usually the most demanding data-creation component is the high-speed digitizer, which transforms a raw analog voltage signal from an optical detector
  • Ultrasonics Beats Optical Methods for Measuring Some Critical Attributes
    these obvious advantages, the applications of traditional a electromagnetic spectroscopy methods are limited, in particular for process analysis in opaque samples and concentrated dispersions as well as samples without required optical activity (absorption spectrum). Therefore, certain physical
  • Automated Optical Positioning Helps Automate FT-IR Analysis
    , and Nicolet Instrument Corporation, Madison, Wisconsin, have maintained their leadership role in infrared spectroscopy with the development of the Nic-Plan microscope, an instrument that offers the highest level of optical automation currently available. The OMNIC FT-IR software for WindowsTM that controls
  • Optical Properties of Aluminum Oxide: Determined from Vacuum Ultraviolet and Electron Energy-Loss Spectroscopies
    Alumina has a variety of applications as a structural ceramic and as an optical material, for example, in sodium-vapor arc lamps and in thin-film devices. The latter applications make use of the electronic structure and bonding present in alumina. For an understanding and improvement
  • Optical Touch Pointer for Fluorescence Guided
    . The objective of this. study was to develop and evaluate a hand-held optical. touch pointer using a fluorescence spectroscopy system to. quantitatively distinguish healthy from malignant brain. tissue intraoperatively.
  • Near IR Spectroscopy in Process Analysis
    in process analysis?. Interest in NIR grew quickly in the 1980s due to the advent of fiber optics, bright light sources and sensitive detectors. NIR also solved some of the difficult sampling techniques characteristic of IR, because NIR optical paths through liquid samples may be millimeters or even
