  • What is Phase Contrast Microscopy?
    Article - 26 Oct 2022
    Phase contrast microscopy manipulates phase shifts in light as it passes through transparent specimens. By converting phase shifts to changes in amplitude (brightness), the method enables scientists...
  • How a Laser Mode Sensor Will Probe Neutron Star Interiors
    Article - 22 Jun 2022
    A laser mode sensor development by gravitational-wave scientists at the University of Western Australia could be the key to probing beneath the surface of neutron stars. The breakthrough may help...
  • Using Raman Spectroscopy to Detect Nitrogen Deficiency in Plants
    Article - 9 Mar 2022
    An effective sensor could sense nitrogen concentrations, which is one of the main limiting factors for crop growth and agricultural productivity. This article discusses the use of Raman spectroscopy...
  • The Role of Lasers in Diagnostic Tests
    Article - 11 Feb 2022
    Laser-based methods are widely used as part of diagnostic testing to provide non-invasive alternatives to biopsies whilst still recovering molecular-level information that can be used for an accurate...
  • Optics and Precise Wind Generation: A Key Step for Decarbonization?
    Article - 28 Jan 2022
    Developing offshore platforms benefits from accurate diagnostics that are capable of operating independently and providing 'early warning’ information about potential problems. One way of doing this...
  • Miniaturizing Raman Imaging Devices with Hybrid Metalenses
    Article - 29 Oct 2021
    A team at Waterloo has developed new hybrid metalenses for two coherent Raman microscopy techniques, coherent anti-Stokes Raman scattering (CARS) and stimulated Raman spectroscopy (SRS). The team has...
  • Detecting Microplastics with Raman Microscopy and FTIR Spectroscopy
    Article - 24 Sep 2021
    Raman and infrared spectroscopy are highly complementary analytical tools that are sensitive to the vibrational modes of molecular species or materials. Understanding the behavior of microplastics...
  • Developing Spectroscopy for Astronomical Purposes: The Latest Research
    Article - 24 Aug 2021
    Spectroscopy is one of the primary techniques used in astronomy to understand the Universe. Many breath-taking astronomical discoveries in recent decades resulted from advanced spectroscopic...
  • What is Polarized Light Microscopy Used For?
    Article - 25 May 2021
    Polarized light microscopy uses polarized light that travels through a double refracting material, then generated into a high-contrast image via the collection of light by a second polarizing filter....
  • Exploring the Most Recent Developments in Quantum Optics
    Article - 22 Aug 2024
