    Abstract: An apparatus comprises a first light sensor configured with a first field of view; and a second light sensor configured with a second, narrower field of view contained within the first field of view. The first and second light sensors may be arranged to detect light reflected from an illuminated surface, wherein the first and second field of view encompass light from an electric lighting device reflected from said surface and additional light reflected from said surface, e.g. natural light; but the second light sensor is concentrated on a region on said surface so as to exclude glare from objects outside said region, whereas the first field of view extends beyond said region. An illumination level of the environment in which the apparatus is installed may be adjusted to compensate for a change in the additional light based on information distinguishing between the two sensors.

    Abstract: A phase step diffractometer is disclosed that utilizes Fresnel diffraction from a 1D step. The main part of the device is a step with two flat parallel mirrors on either side. The phase difference (PD) is changed by varying the light incident angle and the step height. The diffracted lights from the step are caught by a CCD connected to a PC. By varying PD, the visibility of the three central diffraction fringes changes. This permits low uncertainties in the measurements of wavelength, coherence length, coherence width, plate thickness, surface topography and fine displacement of objects. In addition, the device can be used in determination of broad spectral line shapes and optical constants of materials.

    Abstract: A novel standard light source with a more simplified construction, which is suitable for measurement of total luminous flux of a light source different in luminous intensity distribution characteristics from a conventional standard light source, and a measurement method with the use of that standard light source are provided. A standard light source includes a light emitting portion, a power feed portion electrically connected to the light emitting portion, and a restriction portion provided between the light emitting portion and the power feed portion, for restricting propagation of light radiated from the light emitting portion toward the power feed portion. A surface of the restriction portion on which light from the light emitting portion is incident is constructed for diffuse reflection.
