Title: Method and apparatus for measurement of mass of stuck substance on surface of object
Inventor: SUGIMOTO OSAMU
IPC: G01N21/63
Filed: 1995-04-26
Abstract: PURPOSE: To measure an average stuck amount and a distribution state by a method wherein an insulator is turned and moved, a laser beam irradiation part and a measuring part are made movable and many points on the surface of the insulator are measured. CONSTITUTION: Na atoms which are stuck to the surface of an insulator 6 are thermally excited while they are being irradiated with a laser beam. Light is emitted, it is selected at a specific wavelength in a measuring part 4, it is transduced into an electric signal so as to be sent to a control part 1, a noise is removed, and all quantities of the laser beam are accumulated. When a pulse-shaped laser is generated repeatedly, since stuck salt in an irradiated position is diffused and reduced, excited and emitted light is also reduced, the salt is evaporated wholly, and an output signal becomes zero. Since the generation of the laser beam is stopped at this time, quantities of the laser beam generated during this time are accumulated.  Then, a stuck amount is determined on the basis of the relationship between the total quantity of the laser beam which has been found in advance and a stuck salt amount. Under the control of the control part 1, the insulator 6 is moved up and down and turned, the direction of a light irradiation part 2 and that of the measuring part 4 are changed, the same measurement is performed, stuck amounts in many points on the surface of the insulator 6 are measured, their mean value is found, so that the distribution state of the stuck amounts can be measured.
