摘要： In a method of forming an image in a form of pixels, the density distribution around a target pixel is obtained by processing image signals of pixels neighboring the target pixel. The target pixel is sub-divided into a plurality of sub-pixels which form of matrix of n rows.times.m columns. The sub density distribution of the sub-pixels in the target pixel is assumed from the density distribution of the neighboring pixels. The density of each of sub-pixels is determined by multiplying the density of the target pixel, by a constant P and a density ratio of the corresponding sub-pixels in the sub density distribution.

摘要： A process of measuring a shape while changing the relative posture of an microscopic interferometer to a sample lens which is rotated about a rotation axis is divided into a process of measuring a top surface in a state where the sample lens is supported from a back surface and a process of measuring a back surface in a state where the sample lens is supported from the top surface. By combining first shape information of a flange side surface acquired by the process of measuring the top surface and second shape information of the flange side surface acquired by the process of measuring the back surface, the relative positional relation between the sample top surface and the sample back surface is calculated.

摘要： An eyepiece, consisting of two lens groups, is lighter in weight and more compact than known previously, yet has aberrations that are favorably corrected despite the eyepiece having a large exit pupil diameter. This is accomplished by including a predetermined diffraction optical element (DOE) surface on one of the optical elements in order to minimize the number of lens elements that are required, while simultaneously ensuring the image is of high quality. Thus, a high quality image may be observed even while walking, riding in a vehicle, or the like. In order from the eye side, the first lens group has positive refractive power with its surface nearest the eye side being convex and its surface farthest from the eye side being concave. The first lens group may be formed of a single lens element or a pair of lens elements that are cemented together. Among the two lens groups, the eyepiece includes at least one negative lens element and at least two positive lens elements. Preferably, specified conditions are satisfied to ensure that the eyepiece is compact, yet well-corrected for aberrations.

摘要： The relative position of a test surface is sequentially changed from a reference position where a surface central axis is aligned with a measurement optical axis such that the measurement optical axis is sequentially moved to a plurality of annular regions obtained by dividing the test surface in a diametric direction. The test surface is rotated on a rotation axis whenever the relative position is changed. Measurement light composed of a plane wave is radiated to the rotating test surface, and a one-dimensional image sensor captures interference fringes at each of a plurality of rotational positions. The shape information of each annular region is calculated on the basis of the captured interference fringes at each rotational position, and the shape information is connected to calculate the shape information of the entire measurement region.
