COATINGS TO INCREASE DETECTION DISTANCE TO OBJECT DETECTED BY MEANS OF ELECTROMAGNETIC RADIATION OF NEAR INFRARED RANGE Russian patent published in 2020 - IPC G01S17/06 G01S17/93 C09D5/33 

Abstract RU 2728836 C2

FIELD: providing traffic safety.

SUBSTANCE: invention relates to the field of traffic safety and concerns a method for increasing the detection distance to the surface of an object illuminated by near-infrared electromagnetic radiation. Method includes detection by means of detector of electromagnetic radiation of near infrared range reflected from object, at least partially coated with reflecting in near infrared range, which increases the detection distance by at least 15 % when measured at the wavelength of the near infrared range compared to the same object with a matched color coating, which absorbs more than the same radiation from the near infrared range. Coated color coating has a color difference value equal to 1.5 or less compared to a reflecting coating in the near infrared range.

EFFECT: technical result consists in increase in detection distance of object illuminated by near-infrared electromagnetic radiation.
