Description

Title of the invention: System for viewing faces hidden by hoods, scarves or fabrics using ultraviolet lighting. State of the prior art

[0001] Searches of patent databases did not reveal any inventions in this area; however, it is possible that some patents exist and are being withheld for reasons of national security and defense. Statement of the invention

[0002] The present invention relates to a system for using ultraviolet lighting to visualize faces masked by hoods, scarves or fabrics. It comprises the following equipment:

[0003] - an ultraviolet lighting device for the UVB-UVC ranges, covering the range wavelength from 310 to 200 nm.

[0004] - a visible light projector.

[0005] These two devices are synchronized and can operate in continuous mode and in flash mode.

[0006] - a camera equipped with ultraviolet detectors.

[0007] - a camera for visible light, synchronized in time to the previous one.

[0008] - two remote recorders and means of transmission and processing of the images.

[0009] Important note

[0010] It should be understood that the preceding descriptions are given as examples and that they in no way limit the scope of the invention, which would not be departed from by replacing the equipment described with other equivalents. Industrial applications

[0011] The present invention is intended for the visualization of masked faces and, subsequently, for the identification of individuals who take advantage of their impunity to attack, loot, damage public and police buildings, industrial sites and steal from stores and warehouses.
