Abstract: An apparatus for measuring characteristics of an electronic display panel includes an array of optical elements. Each optical element has a first surface and a second surface. The first surface faces the electronic display panel and receives light from pixels of the electronic display panel. The second surface faces away from the electronic display panel and has an area smaller than the area of the first surface. The second surface emits a combined version of the light received by the first surface. The apparatus further includes a light sensor facing the second surface to measure one or more parameters of the emitted light.

Abstract: An imaging device includes laser diodes (LDs) generating near-infrared wavelength light, lenses configured to deliver the light to tissue, a first receiver having one or more detectors, and a first part with at least one of the LDs capable of being pulsed. The first receiver receives light reflected from the tissue and is synchronized to the pulsed light and configured to perform a time-of-flight measurement. An infrared camera receives light reflected by the tissue from a second part of the imaging device. The camera captures light while the second part is off, and while the second part is on to generate corresponding signals, and differences the signals to generate an image. An array of LDs generates a grid of spots on the tissue, which is reflected to the camera. A coupled phone, tablet, or computer receives and processes the time-of-flight measurement, the image, and the reflected grid of spots.

Abstract: A system and method for the detection of bacteria on a sample, utilizes spectroscopic analysis of the sample and the fluorescent properties of bacteria or other substance(s) or matter associated with the bacteria to identify the presence of bacteria on the sample. A detector analyses light emitted from the sample in response to illumination. The detector 5 is arranged to analyze the emission spectra across two wavebands, a first waveband containing the wavelengths associated with the fluorescent properties of the bacterial species or other substance or matter to be detected, and a second waveband excluding these wavelengths but also having an overlapping region with the first waveband.
