Abstract:
A system and method for performing field measurement and testing of a plurality of widely spaced laser beams used in visual warning technology (VWT). VWT uses a combination of widely spaced laser beams, to warn civilians from approaching too close to military security areas. The widely spaced laser beams are displaced using rhomboidal prisms. Each rhomboidal prism receives a corresponding laser beam and displaces it toward a collecting lens. The lens focuses the displaced beams received thereon onto an imaging sensor for testing. Beam shutters may be used for selectively blocking one or more beams in order to test the beams separately and in different combinations.

Abstract:
A device for imaging light, or a source of the light, includes a window for receiving incident light from the source, at least one metasurface, and at least one wedge prism. The metasurface and the wedge prism form a Risley pair and are displaced independently of each other. Each of the metasurface and the wedge prism are operative to deflect the incident light at an angle that is different from an angle of light incident upon them. Each metasurface includes a plurality of sub-wavelength structures that are operative to interact with the incident light received from the window. The device also includes a lens system that is operative to transmit the incident light received from the at least one metasurface and the at least one wedge prism and focuses it on a focal plane.
Abstract:
The present invention relates to a device for detecting an analyte in a sample, of which the sensitivity is improved by changing the structure. The device for detecting analyte in a sample of the present invention has the effect of improving measurement sensitivity and accuracy by arranging a light source and a photosensor to correspond to an inspection area and a control area, forming holes at positions corresponding to respective light source units, the photosensor, the inspection area, and a calibration area, and adding a stick housing having stick housing partitions formed around the holes.
