Abstract: A detecting apparatus for detecting an object includes at least a screen, at least a detecting unit and at least a holding unit. The screen is partial light-permeable and has a first surface and an opposite second surface. The object is disposed adjacent to the first surface of the screen. The detecting unit is disposed corresponding to the object and located adjacent to the second surface of the screen. The holding unit holds the relative distances between the screen, the object and the detecting unit. The detecting unit captures the image of the second surface of the screen so as to calculate the optical field distribution of the object. The detecting apparatus can measure the optical field distribution of an object quickly and has the advantages of low cost and high accuracy.

Abstract: A radiance sensor includes a memory and a microprocessor. The memory stores non-transitory computer-readable instructions and adapted to store a plurality of electrical signals output from a photodetector array in response to electromagnetic radiation transmitted through a lenslet array and incident on the photodetector array. The microprocessor is adapted to execute the instructions to (i) determine irradiance of the electromagnetic radiation in a detector plane from the plurality of electrical signals, each electrical signal having generated by a respective one of a plurality of photodetectors of the photodetector array, and (ii) reconstruct, from the determined irradiance, the 4D-radiance in an input plane, the lenslet array being between the input plane and the detector plane.

Abstract: An aquarium photometer system includes a housing unit, an arm, and a mirror. The housing unit includes a light sensor configured to sense light incident on the light sensor and to convert the incident light to a signal. The housing unit also includes an operational amplifier including a first input node, a second input node, and an output node. The operational amplifier is configured to: receive the signal at the first input node, amplify a difference between the signal at the first input node and a signal at the second input node by a gain factor, and output the amplified signal on the output node. The housing unit also includes a potentiometer connected to the operational amplifier and configured to regulate the amplified signal; and a display connected to the potentiometer and configured to show an intensity of light detected by the light sensor based on the regulated amplified signal. The arm at a first end is connected to the housing unit and configured to move the housing unit around an aquarium case. The mirror is located on a bar and positioned within the aquarium in front of the light sensor and at a focal distance from the light sensor and configured to increase an amount of light incident on the light sensor.

Abstract: An uneven brightness measuring apparatus of the present invention includes a brightness measuring device, a jig, and a measurement data combiner. The brightness measuring device measures an in-plane brightness of a display surface of a measurement sample. The brightness measuring device is mounted on the jig. The jig includes a rotation mechanism to rotate the brightness measuring device about a nodal point of the brightness measuring device. The measurement data combiner combines first measurement data of a first display area in the display area and second measurement data of a second display area in the display area adjacent to the first display area. These pieces of data are obtained by the brightness measuring device. The second measurement data is obtained through measurement of the second display area by the brightness measuring device rotated in a position different from that in the measurement of the first display area.

Abstract: A technique for identifying a measurement planned position for electromagnetic waves in a three-dimensional space in a simple and easy manner is provided. A position of a measuring unit 200 that is carried by an operator 100 is measured by a position measuring device that is configured to measure a position by laser light. A positional relationship between the measured position and the position of a measurement planned position 601 is displayed on a terminal 300 that is carried by the operator 100. This display guides the operator 100, and the operator 100 identifies the measurement planned position 601 and measure illuminance thereat.
