For some specialist work I've contracted to carry out, I've been given a NightMaster infra-red torch.
When used on its own away from the vehicle, it does not seem to startle or alert animals, but when used while I am by the vehicle or under trees, the beam seems to make the animals look up and become alert.
Does anyone involved in the clever side of optics know if an IR torch can reflect off a car or trees/leaves in such a a way that the 'new' light is moved to the visible spectrum. In the same way that if you shine a coloured light on a coloured surface , the surface colour and reflected light dramatically from the original light and surface colours.
Tanks in advance.
