A system and system for personal pathogen status verifying allows an entity to control access to an area of congregation (AOC) at one or more points of entry (POE) is a configurable manner. In one embodiment, the system may be used for the SARS-CoV-2 virus, but may be similarly used for other pathogens.

Method and apparatus for personal pathogen status verification at point of entry into an area of congregation

An apparatus for producing a pixel-modulated line light source from a point light source in which a fiber optic bundle formed of individual fibers arranged in a cylindrical array forming a tip at one end and having the individual fibers spread to a substantially flat line of fibers at the other end optically coupled with an optical shutter means which is constructed of an array of aperture cells disposd in a straight line region aligned with the flat line of fibers. The transmissivity of the aperture cells is individually controllable by electrical signals.

Line light source

A system for producing an image by a sequence of intensity values representing pixels of the image which employs means for scanning the image at a non-linear rate and further, includes means modulating the basic illumination and intensity of pixels as a function of scanning speed. The scanner provides a reciprocating scan and in a specific embodiment, a bi-directional scan whereby pixels are projected during both forward and reverse line sweep. The scan pattern is typically sinusoidal but can be any repeatable scan. The rate of output of video data is proportional to the rate of scan as is the average intensity of the output.
