Abstract:
A mobile system includes a self-supporting platform (210), a tunable anti-reflective (AR) skin or film (220) disposed on and secured to the mobile platform, one or more actuators (230) and a controller (280). The tunable AR skin or film includes one or more layers that are at least partially transmitting to optical energy at one or more optical wavelengths. The skin or film is substantially flexible and/or stretchable and has an optical AR to incident electromagnetic radiation of a given wavelength which is selectively variable when flexed and/or stretched. The actuators are able to flex and/or stretch the skin or film in response to receipt of a control signal. The controller generates the control signal based on a measured value 256 of the electromagnetic radiation 260 transmitted through the tunable AR skin or film.
Abstract:
The present disclosure relates to a bi-directional reflective optical sensor module, an optical sensing accessory, and an optical sensing device. A bi-directional reflective optical sensor module (5) comprises a light source (110) and a first encapsulant (111), two photodetectors (120) and two second encapsulants (121), and a substrate (140). The bi-directional module emits light and detects light from two directions so that the light can be detected from different parts of a body. The optical sensing accessory and the optical sensing device comprise the bi-directional reflective optical sensor module and other electronic modules to have further applications.
Abstract:
A method and apparatus for improving the safety of a surgical procedure involving delivery of laser energy to a tissue, involves enhancing or increasing the detectability of radiation emitted by the tissue or any portion of a surgical instrument or device by providing a sacrificial material that absorbs radiation emitted during the surgical procedure, increasing the temperature of a surface on which the material is disposed and/or causing damage radiation to be emitted in a way that can be detected by monitoring the temperature of the surface and/or radiation, including infrared and/or visible light, emitted by the surface. In a preferred embodiment of the invention, the radiation absorbing material is a sheath arranged to surround the fiber.
Abstract:
Le dispositif récepteur (1) pour rayonnement laser pourvu d'un détecteur (6) se caractérise par une structure (2, 4) analogue à un guide de lumière agencée avant le détecteur (6). Le guide de lumière peut être flexible de sorte qu'il est possible de déterminer la direction d'incidence du rayonnement laser (3) à partir des temps de transit différentiels des signaux pour arriver aux deux extrémités du guide de lumière (2, 4). Ce dernier peut être muni à l'intérieur ou bien en surface de centres de diffusion.
Abstract:
A target apparatus for detecting laser radiation, or the like, impinging thereon. The target has a support (28) having a plurality of fiber optic fibers (27) mounted thereon with their ends attached to a radiation detector and amplifier (30). A radiation scattering cover (14, 31, 36) covers the fiber optic fibers on at least one side to scatter radiation impinging thereupon adjacent the fibers, thereby changing the angle of light entering the fibers to produce a signal on the detector to indicate a beam of radiation hitting the target.
Abstract:
Dispositif formant cible pour la detection des radiations laser ou autres frappant la cible. La cible comporte un support (28) qui possede une pluralite de fibres optiques (27) dont les extremites sont liees a un detecteur de radiations et un amplificateur (30). Un organe de couverture diffusant les radiations (14, 31, 36) recouvre les fibres optiques sur au moins un cote afin de diffuser les radiations qui frappent la zone adjacente aux fibres, modifiant ainsi l'angle d'incidence de la lumiere penetrant dans les fibres pour produire un signal sur le detecteur afin d'indiquer l'existence d'un faisceau de radiations frappant la cible.
Abstract:
An optical sensor (100) comprises a stack of a substrate (101), a light sensitive component (102), a light conversion layer (104), and a filter layer (105). The substrate (101) has a main surface and the light sensitive component (102) is arranged on the main surface. Furthermore, the light sensitive component (102) is sensitive to a range of wavelengths specified by a spectral response characteristic. The light conversion layer (104) is arranged on the light sensitive component (102) and comprises a conversion material. The conversion material has an excitation band and a spectrally shifted emission band. In fact, the emission band at least partially overlaps with the spectral response characteristic of the light sensitive component (102). The filter layer (105) is arranged on the light conversion layer and has a transmission characteristic which is arranged to at least partially block light incident on the optical sensor (100) having a wavelength from the range of wavelengths specified by the spectral response characteristic of the light sensitive component (102).
