What is the difference in application for near infrared camera data capture as opposed to infrared data capture?
Physics Asked by user43710 on December 18, 2020
I am trying to understand why I would use a near infrared as opposed to an infrared camera for data capture of vegetation health monitoring.
One Answer
The EM reflection from plants is at a maximum in the range of wavelengths from 750nm to 950nm, that is the near infrared. The reflectivity is also highly dependant on the amount of cholorphyll present, and by implication the health of the plant.
The graph is from this website, which has a more detailed discussion.
