    Abstract: A method of visually measuring the brightness of ambient lighting around a display device is disclosed. In this method, first, a reference brightness of the display device is determined depending on a type of display device. Thereafter, information about places where the display device can be used is received from the user, and illuminance values of the display device corresponding to brightness stages are set based on the reference brightness and the place information. Then, the brightness of a reference image is converted into each of the illuminance values corresponding to each of the brightness stages. The converted images with the illumination values corresponding to the brightness stages are displayed to the user, and an image that has a brightness value the most approximate to the brightness of ambient lighting is selected, and the brightness value of the selected image is determined as the brightness of ambient lighting.

    Abstract: An optical component (1) comprises a thin film (2) of an electrically controllable birefringent material confined between substantially planar surfaces (3, 5). A respective electrode structure (9, 11) is provided on each of the surfaces, each electrode structure being patterned such that an electric field applied across the film by means of the electrode structures, when a voltage is applied therebetween, causes modulation of the refractive index tensor of the material such that the wavefront of electromagnetic radiation incident on the component and transmitted through the thin film is divided into Fresnel zones. Crossed polarisers (17, 19) are located on opposite sides of the component.

    Abstract: 赤外線撮像装置及び固定パターンノイズデータの更新方法において、シャッタ機構を必要とせず、かつ観測視野内の全方向からの光が赤外線検出器の検出面に均一に入射しない場合であっても、固定パターンノイズデータの取得を可能とする。このために、信号成分量計算部(52)は、処理の対象の各検出器素子について、各検出器素子により検出された複数回の赤外線の検出信号の分散又は標準偏差を算出し、算出した分散又は標準偏差に基づいて、赤外線の検出信号に含まれる赤外線検出器に入射した赤外線に依存する信号成分の量を算出する。固定パターンノイズ算出部(53)は、赤外線の検出信号と算出された信号成分の量とに基づいて固定パターンノイズ成分の量を算出する。データ更新部(54)は、算出された固定パターンノイズ成分の量で、固定パターンノイズデータを更新する。

    Abstract: The system includes at least one light source generating light energy having a corresponding wavelength. The system's sensor is based on an optical interferometer that receives light energy from each light source. The interferometer includes a free-space optical path disposed in an environment of interest. The system's sensor includes an optical device disposed in the optical path that causes light energy of a first selected wavelength to continue traversing the optical path whereas light energy of at least one second selected wavelength is directed away from the optical path. The interferometer generates an interference between the light energy of the first selected wavelength so-traversing the optical path with the light energy at the corresponding wavelength incident on the optical interferometer. A first optical detector detects the interference. At least one second detector detects the light energy at the at least one second selected wavelength directed away from the optical path.
