Title: Digital image streak camera using tv scanning line
Inventor: MURAKAMI AKITOSHI
IPC: G03B15/00
Filed: 1986-03-31
Abstract: PURPOSE:To immediately analyze the motion of a bright point caused by the motion of particle by converting the linear motion of the particle into the linear motion of a bright line through an optical system, and picking up the image of the motion of the bright line and using electron scanning lines for TV camera for the recording and display of the time and position. CONSTITUTION:A particle light scattering body 3 which moves on an observation surface 2 is irradiated with laser light 1 which is collimated excellently and a cylindrical lens 7 is sited so that a spot image is expanded linearly and formed before the scattered light reaches an image information surface 8 through a condenser lens and an image forming lens 5 which have their optical axes at right angles to the observation surface. This image moves on the image formation surface 8 according to the motion of the particle, so it is picked up by the TV camera image pickup tube 10 of a photographic lens 9 by proper triggering, so that the area of scanning lines is outputted as bright image information when there is an intersection of the linear image moving on the image pickup surface 11 and the scanning lines or an afterimage.

IPC: G02B27/28
Filed: 1987-03-27
Abstract: PURPOSE:To prevent stray light in the inside of an analyzer (a polarizer) by providing a photoabsorbing means on the surface from which other light than a desired signal polarized wave component is emitted, in the analyzer (the polarizer) of an optical isolator. CONSTITUTION:As for a polarizer 4 and an analyzer 5 of an optical isolator, a photoabsorbing coat 9 is provided on all faces C-F being vertical to a face A being a light incident face, and a face B being a light emitting face. As for this photoabsorbing coat 9, the faces C-F are processed like polished glass, and painted in black. Therefore, other light than a desired single polarized wave component which is selected is almost absorbed in this part, reflected by the inner wall of prism holders 1, 2, and not returned to its inside again. In such a way, the stray light in the inside of the analyzer 5 (the polarizer 4) is prevented, therefore, the unstable oscillation of a laser chip which is used as a light source, etc. is suppressed, and optical communication can be executed with high reliability.

Title: Gas laser exciting method and gas laser device
Inventor: JITSUNO TAKAHISA
IPC: H01S3/097
Filed: 1989-03-27
Abstract: PURPOSE:To enhance a laser device in output by a method wherein an auxiliary electrode is arranged in a discharge space, a certain discharge voltage is applied to a primary electrode, and then a pulse voltage whose polarity is opposite to that of the discharge voltage is applied to the auxiliary electrode so as to temporarily enhance the electric field of the discharge space in intensity. CONSTITUTION:When the discharge voltage of a discharge capacitor 13 rises and a voltage between primary electrodes 4a and 4b reaches to a constant voltage Vc close to the withstand voltage of a discharge space C, a pulse voltage Vp of reverse polarity is applied to an auxiliary electrode 16 from a pulse generator 14 through the intermediary of an ionizing gap 15. Then, an electric field gradient of spaces C1 and C2 becomes larger than that when the pulse voltage Vp is not applied. By this setup, the discharge gap 15 starts discharging, the voltage Vp of reverse polarity is applied to the auxiliary electrode 16, and ionized electrons are generated through ultraviolet rays generated with the discharge of the gap 15. The electrons concerned are multiplied in the discharge spaces C1 and C2 through the intermediary of an avalanche mechanism, a spacer between the primary electrodes 4a and 4b becomes conductive, and a large discharge current flows through the spaces C1 and C2 from the capacitor 13. By this constitution, a gas laser of this design can be enhanced in laser output.

Title: Measuring apparatus of reflectance and transmittance of granular aggregate
Inventor: ICHIMURA KIYOSHI
IPC: G01N21/59
Filed: 1988-03-31
Abstract: PURPOSE:To make an apparatus small in size and to dispense with the positional alignment of optical axes and others, by leading a light from a light source onto the surface of a vessel to be measured by two optical fibers. CONSTITUTION:A light from a light source is led onto the surface of a substance to be measured by two optical fiber bundles 10a and 10b, and the fiber bundles 10a and 10b are disposed so that the two optical axes thereof on the size of the substance 2 to be measured intersect each other at prescribed incident angles and from the opposite directions on the surface of the substance 2. Moreover, a reflected light (or a transmitted light) from the surface of the substrate 2 to be measured is led to a light-sensing element 5 (or 7) through a fiber bundle 11 (or 12). First a standard white plate having a reflecting of about 90% is set in place of the substance 2 to be measured, the reflected light is measured, and thereafter the quantity of a transmitted light is measured in the state wherein the white plate is removed. Next, the substance 2 being set, each quantity of the reflected or transmitted light is measured and then the reflectance or the transmittance is measured by computation. This method needs only the alignment of the direction and position of the end part of the optical fiber on the side of irradiation of the light. Since the reflected light or the transmitted light is led to the photo-sensing element by the optical fiber, in addition, it is possible to make an apparatus small in size and simultaneously to dispense with positional alignment and to facilitate an operation.
