    Study Notes

    Medical Instrumentation

    • Medical devices are a fundamental component of health systems, essential for preventing, diagnosing, and treating illnesses and diseases in a safe and effective way.

    Optical Techniques

    • Based on the interaction between electromagnetic radiation (light) and analyte (sample)
    • Energy can be emitted, transmitted, absorbed, or scattered/ reflected
    • Types of optical techniques include:
      • Spectral
      • Atomic
      • Fluoro
      • Chemical
      • Turbid
      • Nephelo

    Electromagnetic Waves

    • Created by vibrating electric charges
    • Can travel through a vacuum (no medium needed)
    • Have a wide range of frequencies and wavelengths
    • People can only see wavelengths around 400-700 nanometers
    • Travel at the speed of light in a vacuum (300,000 km/s or 670,617,000 mi/hr)

    Electromagnetic Spectrum

    • Divided into the following regions:
      • Cosmic Rays
      • Gamma Rays
      • X-rays
      • Ultraviolet Rays
      • Visible Light
      • Infrared Rays
      • Microwaves
      • Radio Waves

    Optical Methods

    • Based on the interaction between electromagnetic radiation and sample
    • Include the following techniques:
