    Abstract: PURPOSE:To make it possible to set precise illuminance automatically in a wide range of illuminance level and make efficient correcting work of an optical measuring instrument such as an illuminometer, etc. CONSTITUTION:A light receiver sliding apparatus 15 is so set as to position a standard light receiver 13 on an optical axis B and light emitted from a diffusion bulb-type electric bulb 11 is received by the standard light receiver 13. The output of the standard light receiver 13 is put in a controlling part 6a and converted into a measured illuminance value. Meanwhile, a set illuminance value to be set at is previously put in an input part 17a. In the controlling part 16a, automatic adjustment of the slit width of a changeable slit 12 is repeated until the measured illuminance value from the standard light receiver 13 becomes equal to the set illuminance value. After a fixed time, the set illuminance value is obtained at the position of the standard light receiver 13. Then, using a light receiver sliding apparatus 15, an illuminometer 14, an object for correction, is shifted to the optical axis B and the read value of the illuminometer 14 to be corrected is recorded and if necessary the sensitivity of the illuminometer 14 to be corrected is so adjusted as to make the indication of the illuminometer 14 to be corrected agree with the set illuminance value.

    Abstract: PURPOSE:To obtain an image pick-up apparatus capable of certainly detecting optical information even if the position of a subject changes, by arranging a light transmissivity variable member between an object to be detected and an image pick-up means. CONSTITUTION:An object 22 to be detected is present at a position of a distance R, R1 or R2 from a projecting lens 29. The reflected light of the light incident from a second light source 28 at this time forms an image at a position of a distance L, L1, L2 from one end part of PSD31 having a total length K through a lens 30. PSD31 respectively outputs currents I11, I12 relating to the image forming position of light incident to the light receiving surface 32 thereof through lines 33, 34. The value of (I11-I12)/(I11+I12) relating to the current I11, I12 is shown as the function of the distance R, R1 or R2. Therefore, the aforementioned distance can be detected by detecting said ratio. The control circuit receiving the value of said ratio controles the light transmissivity of a light transmissivity variable member 26. By changing the light transmissivity of the variable member 26 by this method, the quantity of light received by a light receiving element 27 can be made constant.

    Abstract: PURPOSE:To measure the X, Y, and Z value of a sample stably by equalizing mechanisms which equalize two optical paths on a standard and a sample side in the quantity of light, distributing light energy uniformly in incident luminous flux, and performing zero resetting, standard matching, and measurement in one cycle. CONSTITUTION:Light from a light source 1 passes through a lens and a rotating disk 8 and is distributed through a prism 4 to the sample-side optical path 23 to the sample 10 and the standard-side optical path 24 to a standard plate 11. The light of either optical path passes through an aperture of the rotating disk 8, and reflected light beams from the sample 10 and standard plate 11 are photodetected by the X, Y, and Z photodetectors 13, 14, and 15 of an integrating sphere 12 individually. The quantities of light of those two optical paths are equalized to each other through photodetectors 17 and 19 on the optical paths by the upward/downward movement of a light-quantity adjusting diaphragm 21. The standard plate, sample 10, and a reference standard plate 11 are set and irradiated with light whose quantity is adjusted to find the X, Y, and Z absolute values of the measured sample. Pieces of luminous flux 23 and 24 are passed through three apertures at equal intervals of the rotating disk 8 by turns to perform the zero resetting, standard matching, and measurement in a 120 deg. rotation of the disk 8.
