Abstract: PURPOSE:To securely generate the polarization inversion of a fine pattern with good controllability by irradiating a ferroelectric material with charged particles to plural areas at intervals which are large enough to exert no mutual influence on each other. CONSTITUTION:The areas on the singly polarized ferroelectric material 1 are irradiated locally with the charged particles to form a polarization inversion structure 3. The areas are irradiate with the charged particles at the intervals LB where no mutual influence is exerted. Thus, interference between adjacent irradiated areas is evaded and polarization inversion 3A can be generated independently. After the areas are irradiated with the charged particles at said intervals LB where no mutual influence is exerted, accumulated charges on the ferroelectric material 1 are removed and other areas nearby the irradiated areas where an electric field is removed are irradiated with charged particles while the intervals LB are maintained to generate each polarization inversion 3A independently.

Abstract: PROBLEM TO BE SOLVED: To simply and stereoscopically view an object for observation in a form that all of a plurality of spatial recognition factors held by human including motion parallax are met without a contradiction by an optical means.
SOLUTION: Light from the object 1 for observation is formed by an image formation optical system (microscope optical system 20) and an observed image 12 is projected in the space. By this stereoscopic observation device, the observation direction of the object 1 for observation viewed from the image formation optical system periodically changes by a rotary motor 2A (and a rotation stage 2). Consequently, the image of the object for observation viewed from the different observation directions is formed on the observation side as the observed image 12. Furthermore, the projection direction of the observed image 12 by the image formation optical system periodically changes by being synchronized with the change of the observation direction of the rotary motor 2A by a deflection mirror 7. Thus, a stereoscopic image which can be stereoscopically viewed corresponding to the motion parallax is formed as the observed image 12. When viewed from an observer, the stereoscopic image viewed from a different angle is observed in accordance with its observation angle when the observation angle is changed.

Abstract: PROBLEM TO BE SOLVED: To provide a deformable mirror apparatus in which off-axial aberrations, such as coma aberrations and astigmatism, as well as spherical aberrations, can be corrected. SOLUTION: A predetermined intensity distribution pattern 2a is given to a deformable member 2, on which a reflecting film (mirror face) 3 is formed. With the formed pattern of the intensity distribution pattern 2a, a predetermined form which corrects the spherical aberrations is available as a mirror face form, when pressure is applied to the deformable member 2. Furthermore, a driving actuator for deforming the mirror face is so constituted as to generate pressure with the direction being variable. Thus, the mirror face is deformed giving a peak point which is dislocated from the mirror face center, and off-axis aberrations, as well as the spherical aberrations, can be corrected.
