摘要： A partially coherent light beam from a light source is split between a probe light beam toward an observation object and a reference light beam toward a fixed reflective surface. The frequency of the probe light beam is shifted by optical-modulation means. The probe light beam whose frequency has been shifted is swept in a direction of an optical axis and in a direction orthogonal thereto to scan the object two-dimensionally. Reflected light beam from the object is combined with the reference light beam to generate interference light. A detector receives a time-based interference signal from the interference light obtained from the movement of the probe light beam in the direction of the optical axis and the sweeping in the direction orthogonal to the optical axis to derive therefrom reflection intensity data of the object. In such a configuration, the mechanically moving portion is disposed in the probe optical path. Therefore, changes in the interference characteristics of the light that accompany the mechanical scanning are less likely to occur and optical adjustments are also made easy.

摘要： An optical coherence tomography system which is capable of operating in two or more optical bandwidth configurations for the purpose of trading off between high resolution imaging and high signal-to-noise ratio imaging, wherein the later enables deeper imaging depth. The system and associated methods allow for both high resolution, shallow penetration depth and low resolution, deep penetration depth optical coherence tomography imaging to be performed using a single light source. Methods and apparatus are described that allow a single system to dynamically switch between modes, or to operate in a hybrid mode that achieves a balance between resolution and SNR/depth of penetration.

摘要： In an inner layer measurement method, first irradiation light and second irradiation light having a peak wavelength longer than that of the first irradiation light are formed by changing at least one of a position where light emitted from a lamp is transmitted through a short pass filter and a position where light emitted from a lamp is transmitted through a long pass filter. Then, a first XY sectional surface of a semitransparent body is measured by irradiating the first XY sectional surface with the first irradiation light. A second XY sectional surface positioned on a layer deeper than the first XY sectional surface is measured by irradiating the second XY sectional surface with the second irradiation light. Each of the short pass filter and the long pass filter can transmit the light and has properties of changing a cutoff wavelength according to the position where the light is transmitted.

摘要： A system for generating an image of contoured surface includes a light source that is configured to project an electromagnetic radiation beam onto the contoured surface, wherein the projected beam generates first radiation reflected from a first portion of the contoured surface to form a speckle pattern, and second radiation reflected from a second portion of the contoured surface which is substantially uniform in intensity. The reflected first and second reflected radiation is received by an optical detector, and may be processed. The processing is configured to (1) generate a plurality of images from the first and second reflected radiation, with each image being generated using different coherence length electromagnetic radiation from the light source, and (2) generate a 3-D image of the contoured surface from the plurality of images. Methods for generating a 3-D image of a contoured surface are also disclosed.
