摘要： An optical fiber loop has a gain medium having a gain at an oscillation wavelength and optical circulators 13 and 14. Collimate lenses 22 and 24 enlarge light bean taken from the optical circulators 13 and 14. A polygon mirror 25 is provided on the light axis, and is rotated. A diffraction grating 27 is provided at the receiving position of the light reflected by the polygon mirror 25, and is of a Littrow configuration which reflects the light in the same direction as the incident light. A selected wavelength changes according to an incident angle to the diffraction grating 27, resulting in increase of selectivity owing to twice incident, thereby permitting to change an oscillation wavelength with narrow band even when changing the selected wavelength by rotating the polygon mirror 25 at high speed.

A reflector is disposed at a measurement position, a light interference signal is A/D converted at a regular time interval, and data numbers at timing giving peak and bottom are calculated according to a least-squares method. Based on this, an approximate equation is calculated according to polynomial approximation and a sequence including the number of exponentiation of 2 and converting the data number at a regular frequency interval is calculated. Then, by disposing a measured target at the measurement position, calculating the necessary number of pieces of data for FFT from measured data at each timing according to straight-line approximation and Fourier transforming a light beat signal obtained by an optical interferometer at regular frequency interval, a tomogram having high resolution and high sensitivity can be acquired.

摘要： A northbridge, when detecting a synchronization break of a redundant CPU, stops the operation of an abnormal CPU bus where an error has occurred and the firmware in an FWH instructs the northbridge to inhibit an external instruction. In addition, the firmware save the inside information of a normal CPU connected to a normal CPU bus and cache data on a memory and the northbridge issues reset to all CPUs in the home system board. The firmware then restores the inside information of the CPU save on the memory to the all CPUs and instructs the northbridge to cancel the inhibition of the external instruction.
