Abstract: Optical touch switches are implemented based on the use of light total internal reflection and light scattering concepts. The optical touch switch basically consists of a light source, a light guide, a photodetector, and an electronic controller. The fingertip touching on the touching surface of the optical touch switch leads to the change in electrical current produced by the photodetector. As a result, the electronic control box senses this change of electrical current and allows the electrical load to stay at the desired state. Key advantages include ease of implementation, prevention of the light beam incident directly on the user's eyes, and ability to accept both strong and weak mechanical forces from users.

Abstract: Ultra-low leakage current backside-illuminated semiconductor photodiode arrays are fabricated using a method of formation of a transparent, conducting bias electrode layer that avoids high-temperature processing of the substrate after the wafer has been gettered. As a consequence, the component of the reverse-bias leakage current associated with strain, crystallographic defects or impurities introduced during elevated temperature processing subsequent to gettering can be kept extremely low. An optically transparent, conductive bias electrode layer, serving as both an optical window and an ohmic backside equipotential contact surface for the photodiodes, is fabricated by etching through the polysilicon gettering layer and a portion of the thickness of heavily-doped crystalline silicon layer formed within, and near the back of, the substrate during the gettering process.

Abstract: The present invention relates to a position detection device having a function of an electronic shutter. The position detection device is devised to perform the following: a light sending means sends out emitted light, which comes from a light emitting means, to a target object; a two-dimensional light receiving means receives reflected light coming from the target object, and converts the reflected light into an electric charge; and an arithmetic processing means determines a position of the target object on the basis of a light receiving signal from the two-dimensional light receiving means. In addition, the two-dimensional light receiving means has a function of an electronic shutter for discharging an accumulated electric charge in order to adjust the quantity of received light. Moreover, the arithmetic processing means can drive the light emitting means within a period of time during which the electronic shutter is stopped and the two-dimensional light receiving means is accumulating an electric charge.

Abstract: A three-dimensional image capturing device comprises a light source for irradiating a distance measuring light beam to a subject. The light source has a plurality of light source rings, each of which is formed of a plurality of LEDs. The LEDs are annularly disposed along an outer periphery of a lens barrel.

The intensity of the distance measuring light beam irradiated by the light source rings is modulated by selecting the light source rings to be turned ON, so that the intensity of the distance measuring light beam changes in accordance with the time.

Abstract: A nonlinear optical crystal is composed of 2-adamantyl-5-nitorpyridine (AANP) allowing the type 2 phase matching to the sampling light and a measuring object light, emitting a sum frequency light of the measuring object light and the sampling light, with the polarization directions thereof being perpendicular to each other, when the sampling light and measuring object light multiplexed by a multiplexer are entered. When the sum frequency light is emitted through the nonlinear optical crystal, a control portion controls the polarization direction of the sampling light so as to be parallel to a predetermined reference axis located within a plane perpendicular to a phase matching direction of the nonlinear optical crystal. The predetermined reference axis is a single axis maintaining parallelism with the crystal axis of the nonlinear optical crystal even if the wavelength of the inputted light is changed.

The data-processing apparatus also includes an optical detector for receiving the non-biased light and the biased light, thereby producing a first signal corresponding to the non-biased light and a second signal corresponding to the biased light. Based on the first and the second signals, a focus error signal and a spherical aberration signal are produced.
