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.
Claims6
A method of identifying the output energy, main wavelength, position and pattern of near infrared laser light, which comprises (1) irradiating a photosensitive coloring medium comprising (a) a base material, (b) a heat sensitive coloring material containing a basic colorless dye and an organic developer, and (c) a light absorptive material releasing heat sufficient for coloring said heat sensitive coloring material by absorbing the light and having the maximum adsorption wavelength at the wavelength region of from 600 nm to 1500 nm, by the light with a wavelength of from 600 nm to 1500 nm, and (2) identifying the output energy, main wavelength, position and pattern of near infrared laser the light from the colored extent directly by naked eye.
