# Detect Polyethylene

How can we detect polyethylene from a distance?

The method should be mobile as I am thinking of employing it a mobile robot.

I have no idea about it.

Any suggestion or external link would be welcomed.

• It looks problematic at best. There are many types of PE; also it would be very hard to discern if it's not PP for example. – Mithoron Apr 9 '15 at 15:27

• When I google for hyperspectral imager, many different companies selling products come up. Resonon, Bayspec, Imec, etc. etc. Depending on the setup, I'd expect a very basic camera to be $15000 to$30000 or more. – Curt F. Apr 21 '15 at 19:38
