Abstract: A wavelength monitoring system for continuously monitoring the wavelengths of different optical channels transmitted through a wavelength division multiplexed (WDM) fiberoptic system. In one construction, an optical diffraction grating is used to disperse the light being monitored onto a rotating polygon having mirrors on the facets thereof, such that the rotating polygon reflects the light onto a detector located behind a slit. In a second construction, the light is projected onto a rotating, hollow transparent cylinder having a thin film filter deposited on a surface thereof, wherein the thin film filter comprises a Fabry-Perot structure which has a gap which varies as a function of its position on the rim of the cylinder, such that the varying gap allows for a varying transmission wavelength which varies as a function of angular position. A detector is positioned in the interior of the cylinder to detect light passing through the rotating thin film filter.

Abstract: An optical filtering device incorporates first and second prisms, the latter prism counteracting the angular dispersion of the former prism. A spatial light modulator provides a positionally variable optical stop located to block radiation within a wavelength interval and received from a location within a scene. Unobscured radiation from that and other scene locations passes to a camera, which produces an image on a display. Opaque pixels in the stop are positioned to block unwanted light sources. The invention attenuates potentially dazzling monochromatic radiation while retaining radiation at other wavelengths for imaging purposes.

Abstract: An optical system (20) provides a variable dispersion that helps to collect multi-spectral information on an object within the field of view. The system (20) includes at least two sets (24, 26) of optical elements (42x 42y, 44x, 44y) that have minimal deviation of a center wavelength and a non-zero deviation of at least one other wavelength. By rotating the sets of optical elements (24, 26) relative to one another or together, the degree of wavelength dispersion and the direction of the wavelength dispersion can be varied, respectively. By selectively rotating the sets of optical elements, the system also can be operated in a non-dispersed “white light” mode with no net dispersion at the image plane.

Abstract: An optical spectrum analyzer 100 and a wavelength variable light source 101 have each a sweep synchronization start function. A correction function of the rotation speed of a motor 106 for varying the angle of a diffraction grating in a spectroscope 104 so that extracted wavelength and output signal light wavelength match over a setup sweep wavelength range is found from the output signal light wavelength characteristic relative to the rotation angle of a spectral element 119 and the extracted wavelength of the spectroscope 104, and the rotation angle of motor 106 for driving the spectroscope 104 is varied for each setup wavelength in accordance with the correction function, then sweep is performed.

Abstract: The invention concerns a device for adjusting angular play on a predetermined angular range of an optical element mobile in rotation relative to a frame. Said device comprises a contact piece (3), integral with the optical element, and an elastic steady arm (4). The steady arm has a first end (41) fixed to the frame and a second end (42) co-operating with the contact piece when the mobile element is oriented in the predetermined angular range, at least when the mobile element enters said angular range in the rotational direction (S1), such that the steady arm exerts on the mobile element a counter-torque. Said second end does not co-operate with the contact piece when the mobile element is oriented outside the angular range.

Abstract: Very generally, the gas analyzer of the invention includes a source of infrared energy, a sample cell for containing an analyte gas mixture positioned in the path of infrared energy, and a monochrometer including a movable diffraction grating for producing a beam of infrared energy wherein the constituent wavelengths are spetrally separated. The device also includes a wide band interference filter for transmitting a predetermined wavelength band spanning the characteristic absorption wavelength of each of a plurality of constituent gases in the analyte gas mixture. A detector positioned to receive radiation passing through the filter produces an electrical response related to the infrared energy impinging thereon. The monochrometer includes provision for moving the diffraction grating to sequentially cause infrared energy of different wavelengths to impinge upon the detector, and for intermittently causing infrared energy directed toward the detector from the source to be blocked by the interference filter.

Abstract: In order to start sweeping an optical spectrum analyzer 1 and a wavelength tunable light source 14 on the same timing, a motor 6 for driving a spectroscope 4 in the optical spectrum analyzer 1 is controlled. To this end, a drive circuit 7 outputs a control signal to determine the timing where the motor 6 starts to rotate. A wavelength control circuit 19 in the wavelength tunable light source 14 controls the sweep of the wavelength of single-mode oscillation from a light source unit 20 and starts sweeping the light source unit 20 in response to a signal externally supplied to control the timing of sweep start. As a result, the sweep of the wavelength being measured with the optical spectrum analyzer 1 and that of the wavelength of single-mode oscillation from the wavelength tunable light source 14 are started on the same timing and high-speed sweep is achieved.
