تعريف bolometer في الإنجليزية الإنجليزية القاموس.: A sensitive device for detecting and measuring the energy of electromagnetic radiation; an infrared detector that functions by measuring the heating effect of the incident radiation; {i} instrument to measure radiant energy; An instrument for measuring minute quantities of radiant heat, especially in different parts of the spectrum; called also actinic balance, thermic balance; an IR detector where changes in temperature of the responsive element due to incident radiation causes a change in conductivity of the element; an instrument that measures heat radiation; extremely sensitive; the most sensitive thermometer known to science Invented in 1880 by astronomer Samuel P Langley, the bolometer is used to measure light from the faintest stars and the sun's heat rays It consists of a fine wire connected to an electric circuit When radiation falls on the wire, it becomes very slightly warmer This increases the electrical resistance of the wire The difference in conductivity is proportional to the incident irradiance; A device for measuring the total amount of radiant energy received from a celestial object; A microwave or far-infrared detector that operates by measuring the change in temperature of an absorber when illuminated by EM radiation; Instrument for measuring the intensity of radiant energy Its principle is based on the variation of electrical resistance, with the incoming radiation, of one or both the metallic strips which the instrument comprises
