In this lecture, an overview of the different types of passive optical instruments for earth observation is given. Their limitations are outlined, and possible future development paths of such instruments are discussed.
Passive optical instruments on satellites such as spectrometers and radiometers detect sunlight reflected from the earth. They allow us to measure land and atmospheric properties for applications such as agriculture and climate science. In this lecture, at first the most prevalent types of such instruments are introduced, such as for example spectral band-pass imagers and grating spectrometers. Some of the design trade-offs and performance limitations are discussed, and possible sources of errors in available earth observation data are outlined. After that, more innovative instrument designs from the recent time are introduced. The lecture will finish with a speculation on the future of passive optical instruments for earth observation, which will likely see a deeper integration of instrument design and data science in the future.
