Abstract:
본 발명의 일 태양에 따르면, 비-동력으로 동작하는 광도계에 있어서, 몸체; 및 상기 몸체에 형성된 복수의 협각 광 수신기(Narrow Angle Probe)들을 포함하되, 상기 복수의 협각 광 수신기들은 각각 상이한 방위각의 범위에서 들어오는 대기의 광을 수신하고, 상기 수신된 광과 상기 수신된 광에 대응되는 협각 광 수신기의 방위각의 관계를 참조로 하여 상기 대기의 특성을 분석하도록 지원하며, 상기 광은 직사광선 및 간접광 중 적어도 일부를 포함하는 것을 특징으로 하는 광도계가 제공된다. 본 발명에 의하면, 광도계가 비-동력으로 동작하므로, 빠른 시간 내에 광도 측정이 이루어질 수 있고, 광도계가 탑재된 차량 또는 비행기가 이동하지 않거나 적은 거리만을 이동한 채 광도 측정이 이루어질 수 있기 때문에, 측정의 시간 또는 위치의 차이로 인한 오류의 문제점을 방지할 수 있게 되는 효과가 달성된다.
Abstract:
A system is provided for determining personal ultra-violet (UV) radiation measurements, comprising: a measurement device configured to measure UV irradiation; and a terminal device configured to receive or capture an output of the measured UV irradiation from the measurement device and to determine a specific user's personal UV exposure risk level based on at least the measured sun irradiation and information of a skin type of the specific user. The measurement device configured to measure UV radiation exposure includes a surface that includes a plurality of different sections that each have a different sensitivity to UV radiation exposure, and each of the plurality of different sections are configured to display a different color in response to the UV radiation exposure.
Abstract:
A non-power-driven photometer is provided, the photometer comprising: a body; and multiple narrow angle photoreceivers (narrow angle probes) formed in the body, wherein the multiple narrow angle probes receive light in the atmosphere, which is incident over a range of different azimuth angles, and allow the characteristics of the atmosphere to be analyzed with reference to the relationship between the received light and the azimuth angle of the narrow angle probe corresponding to the received light. According to the present invention, since the photometer is driven without being supplied with power, light intensity measurement can be performed in a short time. Further, since light intensity measurement can be performed with no movement or only a short-distance movement of a vehicle or airplane equipped with the photometer, the problem of errors caused by differences in the time and location of measurement can be prevented.

Abstract:
A turbulence-free CCD camera system with nonclassical imaging resolution, for applications in long- distance imaging, such as satellite and aircraft-to-ground based distant imaging, utilizing an intensity- fluctuation correlation measurement of thermal light. The proposed camera system has the following advantages over classic imaging technology: (1) it is turbulence-free; (2) its spatial resolution is mainly determined by the angular diameter of the light source. For example, using sun as the light source, this camera may achieve a spatial resolution of 200 micrometer for any object on Earth. 200-micrometer resolution is insignificant for short distance imaging, however, taking a picture of a target at 10-kilometer, a classic camera must have a lens of 90-meter diameter in order to achieve 200-micrometer resolution. Unlike a classic camera, the proposed turbulence-free CCD camera system has adequate spatial resolution zoom a long distance and still distinguish the objects within a small area, even with a small lens.
Abstract:
A solar radiation detector comprises a shading element that casts a shadow over one of a number of sensors disposed about the shading element. The shading element and the sensors are spaced in relation to each other that the shadow cast by the shading element always falls on one of the sensors, completely shading that one sensor, while at the same time leaves at least another one of the sensor completely exposed to direct solar radiation. The completely shaded sensor measures substantially only diffuse solar radiation.
