Abstract: An imprint apparatus for imprinting a mold pattern onto a substrate or a member on the substrate includes a light source for irradiating a surface of the mold disposed opposite to the substrate and a surface of the substrate with light; an optical system for guiding the light from the light source to the surface of the mold and the surface of the substrate and guiding reflected lights from these surfaces to a spectroscope; a spectroscope for dispersing the reflected lights guided by the optical system into a spectrum; and an analyzer for analyzing a distance between the surface of the mold and the surface of the substrate. The analyzer calculates the distance between the surface of the mold and the surface of the substrate by measuring a distance between the surface of the mold and a surface formed at a position away from the surface of the mold.

Abstract: In an OCT apparatus used in ophthalmology, if a working distance between an eye to be inspected and an objective lens varies, a shape of an obtained tomographic image is changed. This means that the OCT apparatus cannot be used for examining a variation of eyeball shapes. Provided is an optical coherence tomographic imaging method, including: acquiring a first distance between the eye to be inspected and the objective lens, corresponding to first tomographic image of the eye to be inspected; and correcting the first tomographic image to be second tomographic image corresponding to a second distance between the eye to be inspected and the objective lens, which is different from the first distance.

Abstract: An OCT apparatus that photographs with a plurality of measuring beams concurrently has a mechanism for adjusting the optical path length of a reference beam for each measuring beam. Accordingly, when tomographic images photographed in this manner are displayed side by side, because the depth of photographing varies from one tomographic image to another, it is difficult for an operator to comprehend the positional relation between the photographed images. In displaying tomographic images acquired with a plurality of measuring beams, the display position of each tomographic image is adjusted based on the changed optical path length of a reference beam of the measuring beam used for the image. The tomographic images are thus aligned in height and are presented in a manner that is easy for the operator to comprehend the positional relation between the photographed images.

Abstract: A deformable mold includes a first surface at which an imprinting pattern is formed. The imprinting pattern (i) is used to imprint a pattern on a substrate and (ii) has a variable size, which varies based on an amount of deformation of the imprinting pattern. A second surface is located opposite from the first surface in a direction of thickness of the mold. A plurality of heat generating members that generate heat have a permeability to ultraviolet light and are disposed at one of (i) the second surface and (ii) between the first surface and the second surface, and the plurality of heat generating members directly contact the mold in order to control the amount of deformation of the imprinting pattern to vary the size of the imprinting pattern. A controller independently controls the plurality of heat generating members and the controller controls at least one of the heat generating members so as to effect anisotropic size correction of the mold in an in-plane direction of the mold.
