Title: Position adjusting device
Inventor: UCHIDA JUNZO
IPC: G11B5/53
Filed: 1988-11-09
Abstract: PURPOSE:To reduce the time required for making fine adjustment by generating interference fringes corresponding to the position of an object to be adjusted by using a Twymann type interferometer and moving the object to be adjusted so as to increase the contrast of the interference fringes. CONSTITUTION:After a reference mirror 30 is first moved in phi- and theta-directions for adjusting the attitude of the mirror 30, a reflecting mirror 26 is positioned to a location (a) and a ray of white light from a white-light lamp 21 is led to a magnetic head 29 and reference mirror 30 through a slit 26, lens 24, and beam splitter 27. The magnetic head 29 is moved in x-axis direction so that the contrast of interference fringes which appear in the image pickup output of a TV camera 32 due to interference between reflected rays of light from the head 29 and mirror 30 can increase. After the adjustment is done, the reflecting mirror 26 is moved from the location (a) to another location (b) and another ray of white light is led to the beam splitter 27. Then the magnetic head 29 is moved in y-axis direction so that the contrast of interference fringes which appear in the image pickup output of the TV camera 32 can increase. Therefore, the adjusting time is reduced, since the white rays of light having different coherence lengths are switched to each other without narrowing the extent of the appearance of interference fringes.

Title: Optical scanning device
Inventor: SAWADA AKIHIRO
IPC: G03G15/04
Filed: 1989-10-31
Abstract: PURPOSE:To make constant speed scan at low cost with simple constitution by preventing irradiation light from the light source of a rotary head from being diffused by a 1st light passage part according to a desired image signal and making the light incident on the incidence end of a specific optical fiber from a 2nd light passage part. CONSTITUTION:The irradiation light from the LED 8 of the rotary head 7 while prevented from being diffused by the 1st slit 9 according to the desired image signal is converged by a condenser lens 10 to the core diameter of an optical fiber 12 and made incident on the incidence end of the specific optical fiber 12. At this time, the light from the LED 8 is cut off by the 2nd slit 13 except light corresponding to the specific optical fiber 12, so it is never made incident on other adjacent optical fibers 12. Consequently, the constant-angular- speed motion of the light from the light source can easily be converted into constant-speed motion without using any expensive optical lens system and desired image formation is securely performed.
