摘要： An ocular refracting power measuring system includes a projector system (1) for projecting the image of a light source (4) on the eyeground (7) of an eye to be tested and a light receiving system (2) for condensing the light beam from the eyeground onto a light receiving element (9) disposed at a position substantially conjugate with the pupil (6) of the eye to be tested, whereby the ocular refracting power of the eye to be tested can be measured based on the distribution of light amount on the light receiving element and variations of the distribution of light amount due to the changed amount of light in the light source.

摘要： An ophthalmologic apparatus of an embodiment includes an examination part, moving mechanism, three imaging parts, extracting part and controller. The examination part includes an optical system for optically examining an eye. The moving mechanism moves the optical system. The three imaging parts obtain images of the eye from three different directions. The extracting part extracts a partial image from each of two images substantially simultaneously obtained by a concerned imaging part, the concerned imaging part being two imaging parts except one imaging part among the three imaging parts. The controller is configured to perform automatic alignment that controls the moving mechanism based on a positional relationship between two characteristic parts specified for two partial images or to control for assisting manual alignment that controls the moving mechanism based on an instruction input from an operation means, based on the two partial images extracted by the extracting part.

摘要： The present invention relates to an optical image measuring apparatus for measuring the surface form or inner form of the object to be measured by using an optical heterodyne detection method to produce the image of the measured form. Provided is an optical image measuring apparatus forming a three-dimensional image based on tomographic images of an object, acquired at various depths even when the object moves during measurement. Including a half mirror (6) for dividing a light beam signal light (S) and reference light (R), a frequency shifter (8), a reference mirror (9) and a piezoelectric element (9A) used to change an optical path length of the reference light (R), CCDs (21,22) for receiving interference light beams (L) resulting from interference light produced by superimposing the signal light (S) and the reference light (R) on each other by the half mirror (6) and outputting detection signals, an image forming portion for forming tomographic images based on the detection signals, a measurement depth calculating means (53), and an image processing portion (57). Forming a three-dimensional image or the like based on the arranged tomographic images.

摘要： A method for measuring an optical characteristic of lenses in eyeglasses with frames, a measuring instrument for executing it and collecting and sale systems of optical characteristic image data are disclosed herein.
The measuring instrument is used to photograph pattern projecting images of patterns for optical characteristic measurement by means of a digital camera. The pattern projecting images (17) are projected through the lenses (12R,L) based on an illuminated light. The instrument comprises engaged standing plates for engaging the eyeglasses. Mounted on one engaged standing plate is a screen on which the pattern projecting images (17) are projected.-

摘要： Image forming part 220 forms a 2-dimensional image of the surface of the fundus oculi Ef (fundus oculi image) and a tomographic image of the fundus oculi Ef. The fundus oculi image 212a and the tomographic image Ga captured at the first examination time and the fundus oculi image 212b and the tomographic image Gb captured at the second examination time are stored in an image storage part 212. Position information generating part 214 generates the position information 213a indicating the position of the tomographic image Ga in the fundus oculi image 212a and the position information 213b indicating the position of the tomographic image Gb in the fundus oculi image 212b. The generated position information 213a and 213b are stored in information storage part 213. Image processing part 230 adjusts the position between the tomographic images Ga and Gb based on such position information 213a and 213b.

摘要： First image forming part forms a two-dimensional surface image of a fundus oculi of an eye based on optically obtained data. Second image forming part forms tomographic images of fundus oculi based on data obtained by optically scanning a region of the surface of fundus oculi corresponding to at least part of two-dimensional image. Accumulated image generating part generates an accumulated image by accumulating the formed tomographic images in a depth-wise direction. Extracting part extracts first vascular territory corresponding to a fundus oculi vessel from two-dimensional image formed by first image forming part, and also extracts second vascular territory corresponding to a fundus oculi vessel from accumulated image generated by accumulated image generating part. Specification part specifies a position of a vascular cross sectional region corresponding to a cross section of a fundus oculi vessel in the tomographic image based on extracted first vascular territory and extracted second vascular territory.
