Vyacheslav B. Podobedov

Dr. Podobedov has research experience in numerous areas:

  • Condensed matter physics, molecular analysis, linear and non-linear light scattering, electromagnetic wave propagation and interaction.
  • Physical and optical properties of crystals, molecules, films, ceramics, glass and fiber structures.
  • Ultraviolet, visible, and infrared spectroscopies, radiometry, colorimetry, and image and spectrum processing.
  • Design and applications of scientific instruments, optical spectrometers, RF electronics (up to THz range), verification tests and documentation, software development for scientific applications.
  • In the above field published more than 130 publications.

His current research projects are:

Research in the area of detector metrology, design of optical calibration facilities, sources, and sensors. Developing and calibration of standard transfer and working UV and IR radiometers, and realizing spectral responsivity scales. Broadband UV measurements and radiometric measurement of LED sources. The standards developed have been utilized to improve the radiant power and irradiance responsivity scale in the range up to 24 µm.
