Title: Measuring method for displacement of rotary magnetic head
Inventor: NAKAYA HIDEO
IPC: G05D3/12
Filed: 1983-02-08
Abstract: PURPOSE:To realize tracking control with highly accurate position of revolving height for a VTR, etc. by detecting and measuring the displacement of the revolving height position of a rotary magnetic head with no contact and in real time through an optical detection synchroized with the revolution of the head. CONSTITUTION:The PG pulse obtained from a PG head 18 is supplied to a lamp driving circuit 92 via a delay circuit 91, and a strobo light source 93 emits light synchronized with the revolving position of a magnetic head by the PG pulse. The light of measurement sent from the source 93 is irradiated to the outer circumferential wall surface 15A of a rotary drum 15 from an optical lens 94 via a beam splitter 95. The light of measurement reflected by the surface 15A forms an image on a one-dimensional image sensor 97 from the splitter 95 via an image forming lens 96. A line sensor formed with a CCD, for example, is used and set vertically to the revolving direction of the magnetic head. Thus the revolving height position of the magnetic head can be detected from the image forming position of the light of measurement. Based on this height position, the tracking control is possible with high accuracy.

Filed: 1990-02-01
Abstract: PURPOSE:To make highly accurate measurement at low cost by providing a light condensing optical system for condensing one of the luminous fluxes split by a luminous flux splitting means in the vicinity of the center of curvature of an approximate spherical surface of a surface to be checked. CONSTITUTION:A luminous flux from a laser L which generates a coherent light is divided in half by a cubic beam splitter BS through a beam expander BE. One of the luminous fluxes passing through the beam splitter BS is condensed in the vicinity of the center of curvature of an approximate spherical surface of an aspherical surface MT to be checked by a condensing lens FL. And, the reflecting light from the spherical surface MT is, through the lens FL, cast upon the beam splitter BS. On the other hand, the other luminous flux reflected by the beam splitter BS is reflected by an aspherical mirror MR which generates a reference light and has a small refracting power and, incident upon the beam splitter BS. In this case, if the reflecting lights from the spherical surface MT and mirror MR are combined again at the beam splitter BS, since the intereference fringe is adapted to be one color, the form error of the spherical surface MT can be obtained from the interference fringe of the two luminous fluxes.
