Abstract
A multi spectrum vision aid, use thereof, and a method using the aid. The present invention relates in a first aspect to a multi spectrum vision aid comprising at least two transparent elements, in a second aspect to use thereof and in a third aspect to a method of distinguishing elements in a population.
Claims20
A multi spectral vision aid comprising at least two transparent elements, at least one of the at least two transparent elements comprising:
- a combined filter comprising:
- at least two frequency filters, the at least two frequency filters being substantially different, wherein the at least two filters are adapted to modulate the frequency and/or bandwidth and/or transmittance thereof independently, wherein the at least two frequency filters form a cooperating filter;
- wherein the frequency filters operate in a range from 280 nm-2500 nm;
- and
- at least one modulator for modulating the combined filter between at least a first and a second status over a continued period of time, wherein the modulator is operable at a frequency.
