Title: Ultraviolet ray sensitive coloring material and production thereof
Inventor: TANAHASHI ICHIRO
IPC: G01J1/02
Filed: 1996-10-04
Abstract: PROBLEM TO BE SOLVED: To realize highly sensitive sensing of UV-rays by causing to grow fine metal particles irreversibly from metal ions containing an inorganic substance through irradiation with UV-rays thereby producing a color developing material sensitive to weak UV-rays. SOLUTION: A basic material 3 is bonded 4 with an inorganic object 2 to produce a UV-ray sensitive coloring material which develops only a pale color based on absorption of metal ions when it is not exposed to UV-rays because fine metal particle is not grown at all. When it is exposed to UV-rays, fine metal particles 1 are grown irreversibly and a color based on surface plasmon absorption is developed prominently. Since the fine metal particles 1 diffused under ionic state are brought easily into nonionic state through irradiation with UV-rays, the UV-rays can be sensed with high sensitivity.

Abstract: PURPOSE:To irradiate an object surface at an optional shutter speed with luminous flux which has an optional spectrum distribution to the light emission spectrum distribution of a light source by providing a photoelectric converting means at a specific position of an optical system. CONSTITUTION:The photoelectric converting means 3 uses a photomultiplier tube called a high-speed shutter tube. The luminous flux from the light source 1 is converged by the 1st convergence system 2 and made incident on the photoelectric converting means 3 and only luminous flux having an optional spectrum distribution is selected by a waveform selecting element 4 from the luminous flux from the photoelectric converting means 3 to illuminate the object surface 4 through the 2nd convergence system 5. Then, the output signal of a photodetecting means 15 is utilized to control the driving of the photoelectric converting means 3 by a control part 19, thereby controlling the time and intensity of irradiation of the object surface 6. For example, an optional irradiation time, i.e. shutter speed is obtained by varying the time of light emission from a fluorescent surface 9 by controlling an electrode 10 for photoelectron control between the photoelectric surface 7 and electron lens part 8 of the photoelectric converting means 3.
