Camera system that compensates low luminance by composing multiple object images

In a digital camera using an image pickup device such as CCD, a high resolution and properly exposed image is obtained by composition a plurality of image data of the same object taken by a plurality of image pickup operation when a luminance of the object is lower. Each image data is taken under a condition that an integration time (a charge storage time) of the image pickup device is shorter than a limit integration time causing a camera shake. A position of a frame on the image pickup device from which electric charges of the pixels are read out as the image data is corrected so as to cancel the movement of the camera between the image pickup operations.

Efficient waveguide arrays with optimized matching transitions

An optical interconnection apparatus including waveguide arrays such as waveguide lenses, waveguide gratings and star couplers, has improved efficiency realized using a periodic array combined with an arrangement of matching sections. The array is connected to a slab region containing the array focal point and the purpose of the matching sections is to minimize unwanted radiation by the array outside the central zone of the array. This unwanted radiation is primarily caused by two particular unwanted modes excited at the array junction with the slab, and the resulting loss is minimized by properly choosing the average phase shift applied by each section to said unwanted modes.

Magnetic resonance imaging of living systems by remote detection

A novel approach to magnetic resonance imaging is disclosed. Blood flowing through a living system is prepolarized, and then encoded. The polarization can be achieved using permanent or superconducting magnets. The polarization may be carried out upstream of the region to be encoded or at the place of encoding. In the case of an MRI of a brain, polarization of flowing blood can be effected by placing a magnet over a section of the body such as the heart upstream of the head. Alternatively, polarization and encoding can be effected at the same location. Detection occurs at a remote location, using a separate detection device such as an optical atomic magnetometer, or an inductive Faraday coil. The detector may be placed on the surface of the skin next to a blood vessel such as a jugular vein carrying blood away from the encoded region.
