reproducing spectral signatures

Postby zetreque on October 29th, 2017, 3:47 pm 

Is it possible to artificially reproduce a spectral signature and if so how easy?

say I have some vegetation and I want to reproduce its infrared or thermal signature (the leaves).

How would I go about doing that?

Some thoughts:
-I start out with a full infrared spectrum light and then manufacture a filter somehow?
-I take the leaf of that plant and somehow shine light through it or on it, then project out a more intense light from it.
