摘要： A fundus oculi observation device acts as an optical image measurement device capable of measuring an OCT image such as a tomographic image of a fundus oculi, or the like, and is configured so as to calculate the signal level of the formed OCT image, determine whether the signal level exceeds a threshold value, and change the position of a reference mirror so that the signal level is determined to exceed the threshold value.

摘要： Methods for generating optical coherence tomography intensity maps are provided. A beam of light is generated and divided along a sample path and a reference path. The sample path beam of light is directed to locations in an X-Y plane. Light returned from each of the sample path and the reference path is received. Sets of outputs are generated, each corresponding to light intensities received at different wavelengths of the light source when the beam of light is directed at a particular X-Y plane location, the light intensities including information about a light reflectance distribution within an object in a depth direction Z at the particular X-Y plane location. A set of outputs generated from directing the beam of light at a particular X-Y plane location is high-pass filtered to generate a set of filtered outputs suitable for generating a two-dimensional image intensity map of the object.

摘要： An apparatus is provided capable of forming three-dimensional images of the fundus oculi. The image forming part (220) of the computational control unit (200) forms images of the surface of the fundus oculi (Ef) based on results of detecting the fundus oculi catoptric light from the illumination light produced by the fundus camera unit (1A), in addition to forming tomographic images of the fundus oculi (Ef) based on the results of detecting the interference light (LC) from the OCT unit (150). The controlling part (210) synchronizes the timing of detecting the fundus oculi catoptric light from the illumination light produced by the fundus camera unit (1A) with the timing of detecting the interference light (LC) from the OCT unit (150). The correction processing part (240) corrects the image positions of the tomographic images based on the results of detecting the interference light (LC) from the OCT unit (150) on the basis of two-dimensional images based on the results of detecting the fundus oculi catoptric light from the illumination light produced by the fundus camera unit (1A). The image processing part (230) forms three-dimensional images of the fundus oculi (Ef) based on tomographic images for which the image positions have been corrected.

摘要： A surveying system comprises an electronic level (1) and staff devices (2, 21) belonging to one of two or more groups. The staff devices (2, 21) have staffs (2a, 2b) with bar codes corresponding to groups, to which a staff belongs, and mobile station devices (21a, 21b) installed on the staffs. The mobile station device (21a, 21b) has a mobile station display unit (25) to display working data and a mobile station communication unit (26) for performing wireless communication to and from the electronic level (1). The electronic level (1) has an image pickup unit (7) for acquiring images within a range of working, a control device (8) for extracting staff images from the images, for identifying to which group the bar code pattern of the extracted staff image belongs and for determining the three-dimensional position of the staffs (2a, 2b) based on the staff image, and a main communication unit (10) for transmitting the three-dimensional position obtained to the mobile station device (21a, 21b). The mobile station device (21a, 21b) displays the relationship between the three-dimensional position of the staff as received and the working data on the mobile station display unit (25).

摘要： PROBLEM: Leveling over a wide range of tilt angles with high accuracy conventionally involves the use of two tilt sensors: one low-accuracy broad-range sensor for coarse levelling, and a high-accuracy narrow-range sensor for fine levelling. The use of two sensors with different accuracies and ranges renders the levelling mechanism unnecessarily costly. SOLUTION: Two-stage automatic leveling method and device using a single narrow-range high-accuracy inclinometer mounted on a motorized self-leveling tribrach platform. The inclinometer is assumed not to provide any reliable inclination information outside of its measurement range. The first, auxiliary or coarse leveling stage entails systematically trying out different platform orientations (following a pitch-roll curve) until the platform is oriented such that its inclination falls within the measurement range of the inclinometer. The second, main leveling stage entails fine levelling, based on the angle readings from the inclinometer.
