Sensors and system development requirements

16 Setembro 2025, 08:00 André Maria da Silva Dias Moitinho de Almeida

Introduction to sensors
  • Observable or messengers of information
  • The ideal instrument for detecting electromagnetic radiation (large field, high spatial and spectral resolution, high sensitivity, high dynamic range, high temporal resolution).
  • Discussion of trade-offs with physical causes that take us away from the ideal instrument for detecting electromagnetic radiation. How these trade-offs result in different designs for the sensors (cameras, spectrographs, IFUs, optical telescopes, antennas, and more).
  • System development requirements

System development requirements
  • The different categories of requirements for the development of instruments and their discussion
    • Scientific
    • On the instrument
    • On engineering
    • On the system
