IPC: G11B11/105
Filed: 1988-11-18
Abstract: PURPOSE:To obtain an excellent image by disposing a Faraday element and an analyzer between an image sensing element and an objective lens and by providing a means to control unitarily the acquisition of an image information by said image sensing element and the drive of the Faraday element. CONSTITUTION:An image signal detected by an image sensing element 14 is transmitted to an AD converter 16 to be digitized and then is stored in a memory 17. This memory 17 and a driver 101 are so designed as to be controlled by a controller 17. The control is made in such a manner that a signal from the AD converter 16 is added up when a Faraday element 10 is driven in one direction and that it is subtracted when this element is driven in the reverse direction, for instance. Since the rotation of a plane of polarization is determined by the state of drive of the Faraday element 10, background noise can be erased almost completely and easily from an image given a contrast by magnetization of a sample. By repeating this operation, random noise generated from the image sensing element 14 and a light source 5 can also be improved in proportion to the square root of repetition frequency.
