摘要： A method of profiling a rough surface of an object includes the steps of producing an interference pattern of the object surface (14) using an interferometer (1) to produce an illumination intensity on the pixels of an imaging device (18), varying the optical path difference between the object surface (14) and a reference surface (22) of the interferometer (1) through a range including a position of zero optical path difference for each pixel, calculating values of an interference discriminator function to identify the regions of coherence, gathering at the imaging device (18) and storing for each pixel a plurality of intensity values about the region of coherence - as identified by the state or value of the interference discriminator function calculations - at consecutive data points spaced along the range by a predetermined phase difference, storing for each pixel the relative position of the plurality of intensity values along the range, and calculating from the stored intensity values the difference in height between two selected pixels using methods known in the art. An apparatus for practising the invention is also disclosed.

摘要： In an optical coherence tomography measurement, a controller switches between a measurement initiating position adjusting mode in which the position in the direction of depth of the object in which a tomographic image signal is to be obtained is adjusted and a tomographic image obtaining mode in which a tomographic image of the object is to be obtained. In the image obtaining mode, the tomographic image is obtained from the interference light by the first low coherence light and in the measurement initiating position adjusting mode, the tomographic image is obtained from the interference light by the second low coherence light.

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.
