    Abstract: A laser autocollimator assembly that provides an objective, unambiguous, and simple means to achieve precise (for example, arc second or sub arc-second) alignment between the laser autocollimator assembly and a reference surface. The laser autocollimator assembly relies on optical parasitic interference between a reflected beam from the reference surface and the laser beam in the laser cavity that, when alignment is achieved, results in a disruption of the action of the laser, resulting in a reduction in the output power level of the laser beam. By monitoring the power level of the laser beam, for example monitoring the power level of the reflected beam, it can be determined that alignment has been achieved when the power level of the laser beam has been reduced to a minimum level. The power level can be automatically monitored, thereby eliminating the need for user interpretation.

    Abstract: A spatial light measuring system is disclosed, which is configured to store illuminance data acquired by measurement in a new state as initial data, to make the traveling vehicle run after acquiring the initial data, to save illuminance data acquired by the illuminance measuring instrument as daily management data, and to specify an illuminance measuring position and an image acquiring position based on the speed of the traveling vehicle and to use a correction coefficient due to a distance from the ground to an illuminance measuring instrument mounting position and a correction coefficient due to the speed of the traveling vehicle and is configured to correct daily management data into illuminance data on the ground based on both the correction coefficients and to judge the soundness of the illumination facility based on a comparison between the illuminance data as corrected, the initial data and based on the images as acquired.

    Abstract: The efficiency of the work for measuring electromagnetic waves is increased. A measuring device includes a position information obtaining unit, an electromagnetic wave information obtaining unit, a data storage unit, and a selecting unit. The position information obtaining unit obtains position information of a reflective prism 202, which is measured by a position measuring device 400. The electromagnetic wave information obtaining unit obtains illuminance information measured by an illuminometer 203, which is in the proximity of the reflective prism 202. The data storage unit stores the position information of the reflective prism 202 and the illuminance information in association with each other. The selecting unit compares information of predetermined measurement planned positions with the position information of the reflective prism 202 and selects the illuminance information at a position that has a specific relationship relative to one of the measurement planned positions.

    Abstract: There is provided in a first form, a system including a detector and a reflector disposed about and proximal to the detector, at least of portion of the reflector being disposed in front of the detector. The reflector is configured to reflect at least a portion of the radiation directed to the system at an angle greater than a first predetermined value onto the detector, and the system is configured so that at least a portion of the radiation directed to the system at an angle less than the first predetermined value directly impinges on the detector.
