    摘要： The present invention provides measuring apparatus and method for three-dimensional profilometry of an object, wherein a random-speckle beam and a structured fringe beam are projected onto the object and reflected therefrom for forming deformed random-speckle beam and structured fringe beams that are separately acquired by an image acquiring device thereby obtaining a random-speckle image utilized to determine an absolute phase information of each position on the surface of the object, and a structured fringe image utilized to determine a relative phase information for each position of the surface of the object. Each absolute phase information and each relative phase information corresponding to each position are converted into an absolute depth and a relative depth, respectively. Finally, the depth information of each position on the surface of the object is calculated by combining the corresponding absolute depth and the relative depth whereby the surface profile of the object can be established.

    摘要： A system for measuring the profile or the refractive index of a transparent object by fringe projection techniques is provided and has an image generating device, an image capture device, and an image processor. The image generating device produces a reference image with a long depth of focus. This reference image is emitted into an inspected transparent object, and is distorted by the refractive index and the profile of the transparent object. The image capture device receives the distorted image. The image processor analyzes the difference between the distorted image and the reference image, so as to identify the profile or the refractive index of the inspected transparent object.

    摘要： Disclosed is an optical imaging method and device enabling display and 3D measurement of tridimensional objects (1), whereby at least two individual images are captured one after the other and the image conversion is controlled or regulated differently for these individual images. By employing adjustable optical means (10-14) for the illumination of the object or in the optical path for the imaging of the object on the image converter (15) it is possible to acquire a larger amount of visual information on the object observed than that which is available in an individual image due to the limitations imposed by the design of the converter used (15). The invention relates to processes and design forms of the device enabling recording units to be designed, using simply and generally commercial components, which are able to display and measure larger objects (1) despite a reduced field of vision imposed by the design. This is especially useful for diagnosis in invasive applications in the bodies of humans or animals.

And therefore, it is possible to measure a height of a target object which exceeds an available height of measurement by each of the first and second lighting devices, as well as, more accurate and reliable height may be obtained.
