Abstract: The variable spectroscopic element includes a pair of optical substrates 21-22, four sensors 31-34, four piezoelectric elements 41-44, and a control section. The sensors 31, 33 are arranged to form symmetry with respect to the center axis, which links gravity centers of mutually facing surfaces of the optical substrates 21-22, and so are the sensors 32, 34. The control section calculates, from signals of the sensors 31-34, a distance x between the gravity centers of the mutually facing surfaces, and angles θ, φ each of which is formed by a plane perpendicular to the center axis and the facing surface of the movable substrate 22, to drive the piezoelectric elements 41-44 on the basis of the distance x, the angles θ, φ, and to carry out feedback control and feed forward control with respect to at least one of the distance x, the angle θ, and the angle φ.

Abstract: Provided is an optical sensor interrogation system. The optical sensor interrogation system includes: a light source unit which matches round-trip time of light and wavelength tunable cycle time of light in a resonator and emits light; a sensing unit which receives an optical signal in which a center wavelength periodically tunes, from the light source unit and tunes the center wavelength of the optical signal according to physical changes applied from the outside; and a signal processing unit which receives the optical signal reflected from the sensing unit, detects data, and images the data. In particular, the light source unit includes a delaying unit which delays the round-trip time of light and a tunable filter which tunes the wavelength of light so as to match the round-trip time of light with the wavelength tunable cycle time of light. Accordingly, a Fourier domain mode locking (FDML) wavelength swept laser, which operates at speed of several tens kHz or above, is used as a light source so that strain of a fluid, which changes in a short time interval of 0.1 msec or below, is precisely measured and thus a real-time analysis may be performed at high speed.

Abstract: An integrated circuit for an imaging system is disclosed. In one aspect, an integrated circuit has an array of optical sensors, an array of optical filters integrated with the sensors and configured to pass a band of wavelengths onto one or more of the sensors, and read out circuitry to read out pixel values from the sensors to represent an image. Different ones of the optical filters are configured to have a different thickness, to pass different bands of wavelengths by means of interference, and to allow detection of a spectrum of wavelengths. The read out circuitry can enable multiple pixels under one optical filter to be read out in parallel. The thicknesses may vary non monotonically across the array. The read out, or later image processing, may involve selection or interpolation between wavelengths, to carry out spectral sampling or shifting, to compensate for thickness errors.

Abstract: An Interferometric Modulator (IMod) is a microelectromechanical device for modulating light using interference. The colors of these devices may be determined in a spatial fashion, and their inherent color shift may be compensated for using several optical compensation mechanisms. Brightness, addressing, and driving of IMods may be accomplished in a variety of ways with appropriate packaging, and peripheral electronics which can be attached and/or fabricated using one of many techniques. The devices may be used in both embedded and directly perceived applications, the latter providing multiple viewing modes as well as a multitude of product concepts ranging in size from microscopic to architectural in scope.
