    摘要: A dispersion compensator for the compensation of chromatic dispersion in a multi-channel light signal is provided. The compensator includes a pair of optical structures each having a waveguide and a Bragg grating provided therein. The Bragg grating has a plurality of grating components, each associated with one or a few of the channels to be compensated. An optical assembly propagates the light signal sequentially through both optical structures. The periods of the grating components are selected to allow compensation of chromatic dispersion experienced by this particular channel or these particular channels, thereby taking into account the dispersion slope of the light signal. Tuning means are also provided in order to adjust the dispersion of the grating components of each optical structures, and proper selection of the tuning parameters allows tuning independently both the dispersion and dispersion slope.

    摘要: The present invention is directed towards a lining of a pulsed column which allows for an extended exchange of the solid phase with the liquid phase. The lining is composed of stacked baskets and rings, the baskets having a perforate bottom and the rings having a central hole. The size of the perforations in the baskets are such that the solid phase is retained therein while the central hole in the rings allows the solid phase to pass therethrough and go on to the next lower basket. The inside of the column is subjected to high frequency, low energy pulsations which move the liquid and solid phase in a back-and-forth manner. Additionally, the inside of the column is subjected to extremely low frequency, high energy pulsations so as to remove one portion of the solid phase located in a basket and cause it to go down towards a next lower basket.

    摘要: The method for scanning a turbid medium involves displacing an optical signal source over a first face of the medium and a corresponding optical detector over an opposite face from one respective spatial location to another. Each spatial location is associated with a corresponding input region on the first face and a corresponding output region on the opposite second face. The optical detector in response to optical signals detected from each of the output regions generates a primary set of image data, secondary and/or tertiary image data by scanning the turbid medium using input regions and output regions of different sizes. The various sets of image data obtained may be manipulated in any manner, namely subjected to a data processing technique, so as to, for example, highlight the differences or similarities between the images.

    摘要: A method of optical imaging through a scattering medium is provided in which a fit is made to an inhomogeneous diffusion model. The method facilitates good differentiation between scattering and absorption. The variation of the diffusion curve associated with the presence of an inclusion is considered rather than the diffusion curve itself. An empirical model is provided which describes the variation of the diffusion curve. A linear curve fitting process is performed to provide two parameters, one parameter associated with the scattering property of the inclusion and the other parameter associated with the absorption property of the inclusion.

    摘要: Method and its device for evaluating semiconductor wafers that evaluates semiconductor wafers by estimating the dopant level which is equivalent to the critical value at which the excess minority carrier injection density reaches the high injection state, and that measures the minority carrier lifetime at a low-injection-state exposure condition adapted to said dopant level. Excitation light (emitted by excitation light generator 4) is emitted onto a semiconductor wafer 2 at varying exposure conditions as imposed by an exposure condition controller 9. Detector 6 detects the change in the level of reflected radiation from microwaves emitted by microwave generator 5 onto the wafer 2. The dopant level in the semiconductor wafer 2 is estimated by estimation circuit 10' based on the change in the exposure conditions and the change in the minority carrier lifetime as determined by the change in the microwave level. The minority carrier lifetime is measured by measurement circuit 12 at the exposure condition adapted to said dopant level as detected by exposure condition detection circuit 11. This structure makes possible the estimation of the dopant level in the semiconductor wafer while obtaining the lifetime based on Shockley-Read-Hall statistics, and is thus highly qualified for evaluating the semiconductor wafer 2.
