Abstract
A method of identifying the output energy, main wavelength, position, pattern, etc., of light, which comprises irradiating a photosensitive coloring medium comprising a base material, a heat-sensitive coloring material, and a light absorptive material releasing heat sufficient for coloring the heat-sensitive coloring material by absorbing the light and identifying the output energy, main wavelength, position, pattern, etc., of the light from the colored extent thereof.
