Title: Scanning type information detector
Inventor: SHIBA MASATAKA
IPC: G11B7/1245
Filed: 1989-04-26
Abstract: PURPOSE:To allow the high-accuracy monitoring of position information with the small-sized device by detecting the relation between the driving frequency and deflec tion angle or the deflection angle and diffraction efficiency of a SAW (surface acoustic wave) optical deflecting element, thereby enhancing the detection accuracy. CONSTITUTION:Laser light is introduced onto an optical integrated circuit 23 and an input voltage Vin is applied to a VCO circuit 24. The laser light is diffracted and bent by theta if the SAW 13 is generated by impressing a high-frequency signal 12 of the frequency f changing in proportion to the magnitude of Vin to a SAW electrode 1 at this time. The signal Eo(theta) of an exit light quantity sensor 17 and the data signal Ed(theta) obtd. from a sensor 45 are corrected in a detected light quantity correcting circuit 18 to obtain the stable output signal Ec(theta). On the other hand, the absolute value control of the deflectioni angle is executed by determining Vobtained via an amplifier 27 from the deflection angle theta obtained realized with a deflection angle monitor 19, putting this value and a target deflection angle control voltage Vin into a deflection angle correcting circuit 20 and forming the signal Vout of the SAW control. The detection of the position information at the small size and low cost with the high accuracy is possible in this way.
