An image taking optical system, sequentially arranged from an object side to an image side along an optical axis comprising: a front lens group, a stop and a rear lens group. The front lens group comprises at least a meniscus front-group first lens element with a convex object-side surface. The rear lens group comprises at least three lens elements. Through the means of field adjustments that result in desirable distorted images, the image taking optical system may shorten the total length while enhancing the ability to create a larger field of view for panorama usages in compact cameras and mobile phones.

A substrate processing apparatus and method for dynamic tracking of wafer motion and distortion during lithography are disclosed. An energetic beam may be applied to a portion of a substrate according to a predetermined pattern. The relative positions of one or more targets on the substrate may be determined while applying the energetic beam to the portion of the substrate. A dynamic distortion of the substrate may be determined from the relative positions while applying the energetic beam to the portion of the substrate. Application of the energetic beam may be deviated from the predetermined pattern in a manner calculated to compensate for the dynamic distortion of the substrate.

A digital camera system in which capture, processing and storage functions are partitioned differently than in existing systems. A hand-held digital camera is used with a workstation that may exist in a commercial image processing service center. A minimal amount of image data processing is performed in the digital camera, thereby allowing significant digital camera cost reductions due to lower memory requirements, lower processing requirements, and lower power requirements. Real-time single pass image compression techniques are employed within this digital camera to permit rapid gathering and storage of raw or minimally processed image data. The workstation to which the image data are transferred performs the image processing normally done within existing cameras. This processing takes advantage of the increased computational power that is possible to have in such a workstation, compared to that of a small camera, and the increased time over which such processing may be performed.

A rectifying module is arranged on an upstream side of a flow passage containing a flow velocity sensor. The rectifying module includes mesh members each having a plurality of circular small holes and ring-shaped spacers, wherein the mesh members and the spacers are alternately stacked in an axial direction and integrally joined to one another by means of thermal diffusion bonding. The mesh members have identical structures, in which the plurality of small holes are arranged concentrically at angles of separation of 60 degrees in the circumferential direction about the center of a reference small hole. The small holes are formed over the entire surface of the mesh member continuous with adjoining other small holes. The small holes of one mesh member and another mesh member adjacent thereto in the axial direction are arranged so as to have a phase angle difference of 90 degrees in the circumferential direction.

X-ray radiation is transmitted through and scattered from an object under inspection to detect weapons, narcotics, explosives or other contraband. Relatively fast scintillators are employed for faster X-ray detection efficiency and significantly improved image resolution. Detector design is improved by the use of optically adiabatic scintillators. Switching between photon-counting and photon integration modes reduces noise and significantly increases overall image quality.

An MRI apparatus having an open structure includes a static magnetic field generating magnet including magnetic field generating sources arranged above and below an imaging space and magnetic field fluctuation reducing plates arranged inside the magnet. Gradient magnetic field coils are fixed to the static magnetic field generating magnet so as to not be in contact with the magnetic field fluctuation reducing plates. When the strength of the magnetic field generated by the static magnetic field generating magnet fluctuates due to vibration of the gradient magnetic field coils or other devices during an imaging operation of the MRI apparatus, an eddy current is generated on the magnetic field fluctuation reducing plates in response to the magnetic field fluctuation components. Magnetic flux which cancels the static magnetic field fluctuation components is generated due to this eddy current, and consequently, a time-sequentially stable static magnetic field can be obtained.
