An in-vivo imaging device incorporating a double field of view imaging system, having a wide field of view with moderate magnification, and a narrow field of view with substantially higher magnification, axially superimposed thereon. A single imaging array is used for both fields of view. At least some of the optical elements are shared between both of the two different field of view imaging systems. The imaging elements for the high magnification system, being of substantially smaller diameters than those of the low magnification system, are disposed coaxially with the imaging elements of the low magnification system, and can thus use the same imaging array without the need for deflection mirrors, beam combiners or motion systems. Their location on the axis of the low magnification system means that a small part of the imaging plane, around its central axis, is blocked out by the high magnification components.

The present invention relates to an integrated video camera device and self-adapting automatic focus method. The method includes: using climbing method to a curve composed of an evaluation function evaluating the definition and the definition evaluation values of multiple images acquired continuously, selecting a focus method base on the zooming situation, searching the peak of the curve and driving the lens to reach the focusing position corresponding to the peak of the curve, performing real time motion detection to the lens scenes upon searching the peak, driving the lens motor to startup a new cycle of automatic focus process when a certain degree of fuzzy is judged to appear on the lens scene or the moving scene varies and at a non-focus status. The invention has beneficial effects that the device and the method can effectively determine the focus direction in a variety of zoom magnifications, can 'recognize' images at fuzzy status and accelerate them out of the fuzzy status, and overcomes the problems of the traditional focus method that it is difficult to judge focus direction in the fuzzy region under high magnifications, and the traditional focus method has slow focus velocity and repeated oscillation.

An X-ray generator of this invention has an X-ray monitor that monitors a state of an X-ray emitted from a target. Hence the state of the X-ray can be monitored in real time to maintain the X-ray in a constant state. The X-ray monitor is positioned off the path on which an X-ray transmitted from a first exit window travels. Hence, when the X-ray is emitted from the first exit window to an object to be inspected, the X-ray monitor does not obstruct the approaching of the object to the first exit window. This makes it possible to acquire X-ray images of high magnification.

Interferometric scanning method(s) and apparatus for measuring rotationally and non-rotationally symmetric test optics either having aspherical surfaces or that produce aspherical wavefronts. A spherical or partial spherical wavefront is generated from a known location along a scanning axis though the use of a decollimator carrying a spherical reference surface. The test optic is aligned with respect to the scanning axis and selectively moved along it relative to the known origin so that the spherical wavefront intersects the test optic at the apex of the aspherical surface and at radial zones where the spherical wavefront and the aspheric surface possess common tangents. The test surface is imaged onto a space resolving detector to form interferograms containing phase information about the differences in optical path length between the spherical reference surface and the test surface while the axial distance, v, by which said test optic moves relative to said spherical reference surface is interferometrically measured. Based on an analysis of the phase information contained in the interferograms and the axial distance, v, the deviation in the shape of the aspheric surface from its design in a direction normal to the aspheric surface is determined. In scanning, two cameras having different magnification are preferably used simultaneously with the one of higher magnification observing near the part axis where high fringe densities occur while that of lower magnification observes the full part surface. Special procedures are described for alternately improving accuracy near the axis.

The focusing speed and accuracy and the image visual effect in the focusing process are greatly improved.

Mutual compatibility is established between the measurement with a high magnification and the measurement in a wide region. A pattern measurement apparatus is proposed which adds identification information to each of fragments that constitute a pattern within an image obtained by the SEM, and which stores the identification information in a predetermined storage format.

According to the above-described configuration, it turns out that the identification information is added to each fragment on the SEM image which has possessed no specific identification information originally. As a result, it becomes possible to implement the SEM-image management based on the identification information.
