Sensors and system development requirements

19 Setembro 2024, 11:30 • 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
