.: Top Stories   Lidar Technology Reveals Historic Mayan Site A team of researchers led by archaeologists from the University of Arizona has used a laser mapping system from the air to uncover the buried ruins of an ancient Mayan site. After determining that an area in Tabasco in the southeast part of Mexico was worthy of further study, the researchers zeroed in on a particular location with lidar. Read Article

Harmonic Optical Tomography Can Image Nonhomogenous Samples in 3D Harmonic optical tomography (HOT) is a new technique for imaging microscopic, nonlinear, and inhomogeneous objects. It uses holographic information to generate 3D images of the sample. It is the result of a collaboration between researchers at the University of Illinois at Urbana-Champaign’s Beckman Institute for Advanced Science and Technology and Colorado State University.

.: Upcoming Webinars   Optimize the Signal Acquisition for Optics and Photonics Measurements Tue, Jun 23, 2020 11:00 AM - 12:00 PM EDT This webinar will focus on four optical measurement techniques: tunable diode laser absorption spectroscopy; pump-probe spectroscopy; stimulated Raman scattering microscopy; and carrier-envelope offset stabilization. By taking a close look at these techniques, you will learn how to choose the most suitable measurement scheme, for example, lock-in amplifier or boxcar averager; perform a measurement; and tune your measurement settings to maximize the signal-to-noise ratio.  Register Now  Principles of Laser Power/Energy Measurement Wed, Jun 24, 2020 12:00 PM - 1:00 PM EDT In this webinar, you’ll learn how laser power and energy measurement work. The presenter will clearly define the various beam parameters and look at the technologies typically used for measuring each of them. You will see how these are implemented in various types of instruments and develop an understanding of what type of equipment is best for what type of measurement.  Register Now  CALL FOR ARTICLES!
