Electromagnetic radiation can be described using energy, wavelength, or frequency. Frequency is measured in cycles per second or Hertz, wavelength in meters, and energy in electron volts. While these three quantities are related through precise mathematical relationships, why have three ways of describing things, each with a different set of physical units? In brief, scientists […]

The electromagnetic spectrum is the range of all types of electromagnetic radiation. Radiation is energy that travels and spreads out as it goes. Examples of electromagnetic rations include the visible light that comes from a lamp in your house and the radio waves that come from a radio station. The electromagnetic spectrum contains other types,

What is hyperspectral Imaging? Hyperspectral imaging is an advanced technique that combines spectroscopy and imaging to gather detailed information about the composition and characteristics of objects and surfaces. Unlike human vision, which relies on three color receptors, hyperspectral imaging collects hundreds of images at different wavelengths for the same spatial area. It measures the continuous
