NDT for live plant from literature

I guess you will find here not much colleagues in touch with "NDT" in biology. E.g. my main contact in this field was Laser-Ultrasonic as used in Medicine and Biotechnology just because it was surprising for me that such a "high energy excitation is possible with organic (living) material - I had done projects with this only on metallics and CFRP....
My best information I got in this field via Researchgate.net. This is something like Linked-in for researchers. Best: it is free to access, you have only to register, and you find either papers free to download or you can ask researchers to provide copies. and you have the chance to ask questions into the community. Try this.
Lot of researchers use FLIR-Thermocameras (of course you find also other brands) Checkout with those companies, how they sell their systems in your field of applications. Usually the application engineers know about the researchfields their cameras are used for.
