Plasmon-photon coupled optical devices
InactiveUS20050275934A1Avoid spreadingImprove transmittanceBeam/ray focussing/reflecting arrangementsMaterial analysis by optical meansAngle of incidenceRefractive index
The present invention is directed to optical devices. More specifically, the disclosed devices include a film defining a periodic array of surface elements so as to give rise to surface plasmon polaritons. The film also includes at least a single aperture having a diameter less than the wavelength of light. In one embodiment, the surface elements can be an array of anisotropic apertures and the films can act as a polarizer. The disclosed devices can also include a material having a variable refractive index substantially adjacent to the metal film. For example, the refractive index of the adjacent material can vary according to some characteristic of the light incident to the device, for instance, the intensity or the angle of incidence of the light. In this embodiment, resonant coupling of incident light with the SPP, and hence transmittivity of the device, can depend upon the nature of incident light. The disclosed devices can be useful in, for example, remote polarizers, polarization mode dispersion, isolators, multi-color displays, switches, such as can be controlled according to incident sunlight, or optical filters, such as for eye protection devices, filtering out possibly harmful light.

Eye protection methods and apparatus
An eye protection apparatus includes a selectively darkenable element, such as a liquid crystal panel, and a controller that causes transmission of a darken signal that causes the selectively darkenable element to darken in conjunction with an emission of light, such as intense diffuse light that is used in some medical procedures. Protection against both laser light and diffuse light may be provided in the same eye protection apparatus. The darken signal may be transmitted prior to the emission of the diffuse light, and cause the selectively darkenable element to achieve a darkened state prior to emission of the diffuse light.

Low power phototransistor-based welding helmet providing reduced sensitivity to low intensity light and sharp phototransistor response to high intensity light
InactiveUS6855922B2Total current dropHigh voltagePhotometry using reference valueRadiation pyrometryElectrical batteryEngineering
A sensor circuit for detecting the occurrence of welding is disclosed. The sensor circuit uses a phototransistor operative to receive a light input and produce an output representative thereof. A resistor is coupled between the phototransistor's base and emitter to control the phototransistor's response to low intensity and high intensity light. An amplifier may be coupled to the output of the phototransistor so as to provide a gain for the output of the phototransistor; and feedback means may coupled to the phototransistor to bias the phototransistor, the feedback means comprising a resistor capacitor circuit for following the output of the phototransistor, a feedback transistor to provide a feedback signal to the phototransistor, and a resistor coupled between the base and the emitter of the phototransistor. Preferably the phototransistor is a planar phototransistor having a surface mount. The sensor circuit may also be used in an auto-darkening eye protection device, such as a welding helmet or the like, that delivers a drive signal to a shutter assembly upon the detection of welding, the drive signal being operative to drive the shutter assembly to a darkened, protective state. A solar cell may be used to reduce the circuit's power consumption by powering various circuit components only when the welding helmet is exposed to light. The present invention provides reduced power consumption, improved attenuation of low intensity light signals, a sharp rise time from the phototransistor in response to high intensity light, and allows implementation into a smaller sleeker eye protection device.
