<P>PROBLEM TO BE SOLVED: To provide a light quantum meter capable of measuring photon flux density of a specific wavelength band in a visible light region and a far infrared light region. <P>SOLUTION: The light quantum meter of the present invention comprises: multiple light receiving parts 10a-10b, a signal selection part 30; a signal synthesis part 40; and an output part 50. Each of multiple light receiving parts receives light of wavelengths within mutually different wavelength range in the visible light region and the far infrared light region, and outputs a light intensity signal of largeness according to light intensity of received light. The signal selection part 30 selects at least one of the light intensity signals output from the respective light receiving parts. The signal synthesis part 40 synthesizes the light intensity signals selected at the signal selection part 30. The output part 50 calculates and outputs the photon flux density of the specific wavelength band based on the synthesized light intensity signal synthesized at the signal synthesis part 40. <P>COPYRIGHT: (C)2012,JPO&INPIT |
