单词	radiometer
释义	radiometer /ˌreɪdɪˈɒmɪtə / noun An instrument for detecting or measuring the intensity or force of radiation.The radiometer measured light intensity by the number of revolutions induced over time, and the bolometer measured a decrease in electrical resistance upon absorption of radiation.... The UV-B radiometer is intended to measure the hemispheric radiation reaching a horizontal surface. And that absorption forms the basis by which satellite UV radiometers detect ozone from space. Derivatives radiometry /ˌreɪdɪˈɒmətri/ noun ... We'll cover the fundamentals needed to understand basic optical concepts such as radiometry, polarization, diffraction, and holography. As indicated by Parker, chemical actinometry has several advantages when compared with radiometry for measuring UV radiation. The rates of UV absorption obtained using radiometry in units of einsteins per second are also presented in Table 3.
