    摘要： An electronic device may be provided with a display mounted in a housing. A directional ambient light sensor may measure the intensity and direction of ambient light. The ambient light sensor may be mounted in alignment with a light sensor window formed in an inactive area of the display. The ambient light sensor may be formed from detectors on a semiconductor substrate. Incident light angle restriction structures may define openings for each detector. Each opening may be configured to allow light with a different range of angle of incidence values to be passed to a respective one of the detectors. The ranges of acceptance angle for adjacent detectors may overlap. A sensor may produce a diffuse light reading by processing ambient light data from a diffuse light detector and a directional light detector. The diffuse and directional light detectors may be formed on a common semiconductor substrate.

    摘要： A light distribution characteristic measurement apparatus includes an imaging unit disposed at a predetermined distance from a light source, a movement mechanism that successively changes a positional relation of the imaging unit with respect to the light source, while keeping the distance between the light source and the imaging unit, and a processing module that calculates the light distribution characteristic of the light source. The processing module obtains a plurality of image data taken under a first imaging condition and a plurality of image data taken under a second imaging condition different from the first condition, and determines corrected image information corresponding to a relative position of interest, from first image information corresponding to the relative position of interest included in the image data taken under the first condition and second image information corresponding to the relative position of interest included in the image data taken under the second condition.

    摘要： A transportable goniospectrometer with a constant observation centre for the radiometric measurement of the reflexion behaviour of a natural surface includes a spectrometer having an optical unit and a sensor. A main pillar has a lower and an upper pillar end. An arc has a fixed and a free arc end. A slide is disposed displaceably and fixably along the arc. The slide carries the optical unit orientated towards the observation centre. A cantilever has a fixed cantilever end connected to the upper pillar end via a screw connection, and a free cantilever end which has a suspension that is rotatable and fixable about a vertical axis. The suspension is connected to the sensor and to the fixed arc end of the arc. The suspension is configured to position the arc at a distance of the arc radius of the arc above the natural surface.

    摘要： A photometric device for investigating a sample, comprises an array of radiation sources that are spaced apart from one another, and which are operable to generate radiation that differs from that generated by the other radiation sources in the array. The device includes a lens arrangement for focusing the radiation at a region of space where a sample may be located for example by means of a sample holder, and at least one detector for receiving radiation from the region of space. Preferably, a number of detectors are employed that are spaced apart from one another, and especially about an axis of the device, so that one radiation detector can detect radiation transmitted by the sample and the other detectors can detect radiation scattered by it. The radiation sources may be time division multiplexed so that in each time slot the detectors receive radiation originating from each radiation source. In an alternative embodiment, the radiation from the region of space may be transmitted to the sample via a beam homogeniser, for example an optical waveguide in the form of an optical fibre, which may be used to reduce or remove speckle where laser diodes are employed as the radiation sources. The device may be used to determine the particle size distribution of particles in a sample by a method employing Bayesian inference.
