  • Patent number: 8705024
    Abstract: Measurement cannot be made when trying to measure a wavefront aberration of a wide-angle lens, being wide in a field of view, comparing to a focus distance, by a Shack-Hartmann sensor, since an inclination of the wavefront exceeds an allowable value of inclination of the Shack-Hartmann sensor. The Shack-Hartmann sensor is inclined at a position of a pupil of a lens, and is controlled so that it lies within the allowable value mentioned above. Photographing is made through step & repeat while overlapping at the same position, to compose in such a manner that overlapping spots are piled up, and thereby measuring the wavefront aberration of the lens having a large pupil diameter.

  • Patent number: 8681327
    Abstract: Proposed is a technique for detecting a damaged VCSEL in a short time and at low cost. It shows the light emission spectrum of a multi-mode VCSEL before an ESD damage, and the light emission spectrum which shows several peaks corresponding to the structure of the active layer (MQW) and the upper and lower reflectors (DBR) is obtained. On the other hand, when the VCSEL which has an ESD damage has a damage in the active layer, the light emission spectrum which shows fewer peaks than the original number of peaks is obtained. Accordingly, the light spectrum analyzer analyzes the light emission spectrum, and it is determined that ESD damage has occurred when the number of peaks is equal to or smaller than a predetermined number, e.g., two peaks.

    Abstract: In an analysis system for detecting amounts of components contained in samples, many samples can be measured simultaneously in the whole of the system by use of compact inexpensive photometers. An LED with low heat generation and a long life span is used as a light source. Compactness is achieved by bended optical axis instead of a straight one. Components for bending an optical axis and components for condensing light to ensure an amount of light are in common use to reduce the number of components. Compactness, reduction of the number of components, and integration achieve easy optical axis alignment and precise measurement.

  • Patent number: 8659759
    Abstract: Cavity enhanced absorption spectroscopy systems and methods for detecting trace gases. When the frequency of laser light approaches the frequency of a resonance cavity mode, the laser begins to fill the cavity to that mode. Optical intensity inside the cavity reflects total cavity loss when the laser light frequency coincides with the cavity mode transmission peak. The intra-cavity optical power also depends on the coupling efficiency of the laser beam to the particular cavity mode. Measurement of intensities of three optical signals, namely, intensity of the light incident on to the cavity, intensity of the light reflected from the cavity, and intensity of the intra-cavity optical power, with their appropriate normalization advantageously significantly reduce effects of baseline calibration and drift as the normalized signal only depends on total cavity loss, and not the coupling efficiency, as in traditional approaches.

    Abstract: An optical measurement system includes a holder, a bracket, a plurality of optical sensors, a motor and a processing unit. The holder is provided for holding a test light source at the origin of a spherical coordinate system. The optical sensors are located on the bracket at different elevation angles with respect to the origin. Moreover, the optical sensors are spaced the same radial distance apart from the origin to aim at the test light source. The motor is configured to drive either the holder or the bracket to rotate such that the test light source at the origin is able to relatively rotate with respect to the optical sensors about a zenith axis of the spherical coordinate system. The processing unit is coupled to the optical sensors for processing of data captured from the optical sensors.

  • Publication number: 20130242303
    Abstract: A dual optical metrology system includes a first metrology device and a second metrology device, each producing light at different oblique angles of incidence on the same spot of a sample from different azimuth angles. The dual optical metrology system further includes a rotating stage or flip mirrors capable of altering the orientation of the light beams so the first and second metrology devices can measure the same spot on the sample at different orientations. Thus, the first and second metrology devices generate first and second sets of optical metrology data, respectively, at a first orientation with respect to the sample. After the sample is rotated, the first and second metrology devices generate third and fourth sets of optical metrology data. The first, second, third, and fourth sets of data can then be used to determine one or more parameters of the sample.

  • Patent number: 8451436
    Abstract: To determine as precisely as possible the flow rate of a liquid flow inside a tube by means of minimal technical and especially minimal apparatus complexity the invention provides with a procedure and an apparatus to determine it. In this process the liquid is heated by means of an optical heating beam while the point of heating is shown through by an optical detection ray. The axis of the heating- and the detection beam coincide at least in the point of heating. The detection beam is absorbed via an array of detectors. In the apparatus the heating device which heats the interior area of a limited internal area of the liquid and the optical control unit of the laser beam are arranged that way that a measuring beam shines through the absolute heating point.
