Title: Production of tracking error signal
Inventor: OOGOSHI SEIICHI
IPC: G11B7/09
Filed: 1984-02-13
Abstract: PURPOSE:To correct easily and accurately the beam shift component which is superposed on a tracking error signal by specifying a ratio between a differential signal of two output signals obtained from a photodetector and a differential signal of signals obtained by giving the wave detection to the mean value of a high frequency component and producing a difference signal between both differential signals to use said difference signal as a tracking error signal. CONSTITUTION:A differential signal SA between output signals S1 and S2 sent from photodetecting surfaces 6a and 6b of a photodetector 10 is multiplied by a compensation factor betaB=1/pi by a compensation factor control circuit 10. The high frequency components of both signals S1 and S2 are extracted after transmitting both signals through an HPF11. These components are transmitted through a mean value wave detection circuit 12 to obtain a differential signal SB of both signals. Then a difference signal S'B between both signals SA and SB is used as a tracking error signal. In this case, the shift components contained in signals SB and SC are eliminated by the signal SA when the shift amount of the light beam is smaller than the light beam diameter on a photodetecting surface. For this purpose, the compensation factors betaB and betaC obtained by the 1st and 2nd methods are specified to set the shift component at 0. Thus the stable tracking servo is possible despite fixed factors betaB and betaC since no relation is defined with a shift amount alpha of the light beam. Thus it is possible to obtain a tracking error signal having the corrected superposition of the beam shift component.

Abstract: PURPOSE:To focus an image accurately to photograph image information, by opening and closing alternately two light valves using liquid crystal display devices. CONSTITUTION:If there is no voltage difference between a transparent electrode 37 formed on a panel glass 33 and transparent electrodes 38 and 39 formed on a panel glass 34, light valves 31 and 32 becomes transparent together, and image information is transmitted through them. When a voltage is applied to the transparent electrode 39, a liquid crystal between electrodes 37 and 39 reacts and becomes opaque, and therefore, image information is transmitted only from a left side 31. Next, when the voltage to the transparent electrode 39 is eliminated and a voltage is applied to the electrode 38, image information is transmitted only from a right side 32. A transmission part is moved alternately to positions, which are symmetrical with respect to the line dividing equally the pupil into two, in the pupil by repeating this operation, and this movement is equivalent to oscillation to the left and the right, and therefore, focusing is possible, and left and right light valves are opened simultaneously to photograph image information.

The above mentioned processing is executed concerning all the blocks and all the picture elements of the memory 1. Thus, since filter processing is executed in the subscanning direction when the picture data are handled, band limitation is executed. Then, since an unnecessary component in a band component in the subscanning direction is removed, the picture quality is improved.
