Abstract: This invention provides a sensor array using a plurality of fiber optic sensors connected between transmit fibers and receive fibers. The laser transmitter supplies pulses to the transmit fiber and fiber optic couplers couple the pulses from the transmit fiber into the fiber optic sensors. The pulses from the laser transmitter may be frequency chirped or frequency stepped to provide passive sampling of interferometric sensors in addition to intensity sensors, or otherwise frequency modulated. Each sensor is configured to respond to changes in a predetermined physical parameter by altering the shape of the pulse thereto. Fiber optic couplers couple the sensor output signals into the receive fiber for input to a receiver, which converts the optical signals into electrical signals for input to a processor. A timing reference correlates the sensor output pulses with the sensors.

Abstract: A shearing phase difference sensor including a high energy laser source for generating adjacent coherent light beams. Samples of the beams are extracted by an extracter and directed to an optical modifier. The optical modifier, positioned for intercepting the sample beams from the extracter, diffracts the beams and produces output beams which, in turn, are directed through a lens to a detector. The detector, positioned to intercept the output beams, produces electrical signals indicative of the output beams. The electrical signals are processed by a processor which calculates the phase difference between adjacent coherent light beams. Also, disclosed is a method for measuring the phase difference between adjacent coherent light beams.

Abstract: A method and an apparatus for detecting the wavelength of a laser beam by utilizing an optogalvano effect based upon atoms or molecules in the plasma. Atoms or molecules in the plasma are irradiated with a laser beam. The impedance of the plasma at this moment is detected to determine whether the wavelength of the laser beam is in agreement with a predetermined absolute wavelength. The result of detection is used for controlling the wavelength of the laser beam.

Abstract: An object of this invention is to provide a compact and low-cost optical wavelength measuring instrument, in which mechanical movements are eliminated to improve reliability, measuring speed and measuring accuracy. The optical wavelength measuring instrument utilizes a group delay dispersion medium having wavelength dependence. Light to be measured is introduced to an optical modulator (1) for intensity modulation using a reference signal from a signal source (2). The modulated light is passed through the group delay dispersion medium (3) so as to provide a delay corresponding to the wavelength, and converted to an electric signal by a photoelectric convertor (4). A phase difference between the reference signal and this electric signal is determined by a phase comparator (5) so as to convert the wavelength of light to be measured. The wavelength of light to be measured can be converted by using another reference signal, such as reference light, to which the same optical intensity modulation and the same delay are applied, or delayed light to be measured.

Abstract: The invention concerns a method and corresponding device for determining the phase- and/or amplitude data of an electromagnetic wave. In order to bring about the spatial depth resolution of the image data obtained with such a method, the method according to the invention comprises the following steps: an electromagnetic wave is beamed onto the surface of a photonic mixed element comprising at least one pixel, the pixel having at least two light-sensitive modulation light gates Gam and Gbm and associated accumulation gates Ga and Gb; modulation light gate voltages Uam(t) and Ubm(t), which are configured as Uam(t) = Uo + Um(t) and Ubm(t) = Uo - Um(t), are applied to the modulation light gates Gam and Gbm; a direct voltage, whose magnitude is at least the same as that of the total of Uo and the amplitude of the modulation voltage Um(t), is applied to the accumulation gates Ga and Gb; the charge carriers produced in the space charge region of the modulation light gates Gam and Gbm by the incident electromagnetic wave are subjected, as a function of the polarity of the modulation light gate voltages Uam(t) and Ubm(t), to the potential gradient of a drift field and drift to the corresponding accumulation gate Ga or Gb; and the charges qa and qb which have drifted to the accumulation gates Ga and Gb, respectively, are diverted. The corresponding photonic mixed element has at least one pixel which comprises at least two light-sensitive modulation light gates (Gam, Gbm) and accumulation gates (Ga, Gb) which are associated with the modulation light gates and are partitioned with respect to the incident electromagnetic wave. A plurality of photonic mixed elements can be assembled to form an array.
