Coatings for increasing near-infrared detection distances
First Claim
1. A method for increasing a detection distance of a surface of an object illuminated by near-IR electromagnetic radiation, comprising:
- (a) directing near-IR electromagnetic radiation from a near-IR electromagnetic radiation source towards an object at least partially coated with a near-IR reflective coating that increases a near-IR electromagnetic radiation detection distance by at least 15% as measured at a wavelength in a near-IR range as compared to the same object coated with a color matched coating which absorbs more of the same near-IR radiation, wherein the color matched coating has a Δ
E color matched value of 1.5 or less when compared to the near-IR reflective coating, as measured using an integrating sphere with D65 Illumination, 10°
observer with specular component included; and
(b) detecting reflected near-IR electromagnetic radiation reflected from the near-IR reflective coating.
