Different types of EO sensors

Different types of EO sensors Sensors carried on satellites measure electromagnetic radiation but they need a source of energy to illuminate the Earth. There are 2 main types of sensor: Active and Passive Passive sensors Measure energy which is reflected and emitted from the Earth e.g. sunlight reflected from the earths surface They do not emit their own energy A camera (with its flash off!) is an example of a passive sensor, or the human eye! Passive sensors u sing visible light wavelengths produce images like we see on Google Earth. Diagram of a passive sensor. Credit: NASA Applied Sciences Remote Sensing Training Program
