Title:
METHOD FOR ESTIMATING EMISSION WAVELENGTH OF LUMINOUS BODY AND DEVICE THEREFORE
Document Type and Number:
Japanese Patent JP2015010834
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide, while being provided with equivalent performance to a spectrometer, a method and device for estimating the wavelength of a luminous body with high throughput.SOLUTION: There are provided a method and device for estimating an estimated wavelength of a luminous body on the basis of a preregistered wavelength estimation function and an observed luminance ratio, the method and device comprising: a first observed luminance value output unit provided with a first observation unit for transmitting and observing light of a longer wavelength than a first wavelength which is a criterion for normal light emission and a second observation unit for transmitting and observing light of a shorter wavelength than a second wavelength which is a criterion for normal light emission, the first wavelength being set to shorter than the second wavelength, the first observed luminance value output unit outputting, as a first observed luminance value, the luminance of a specified portion observed by the first observation unit; a second observed luminance value output unit for outputting, as a second observed luminance value, the luminance of a specified portion observed by the second observation unit; and an observed luminance ratio output unit for outputting, as an observed luminance ratio, a ratio of the first observed luminance value to the second observed luminance value.
