摘要： There is described a method for converting the wavelength of a pulsed optical signal. An input pulsed signal containing information and having an input wavelength is buffering by propagating the input pulsed signal in a closed-loop optical regenerative cavity. The propagation comprises converting the input pulsed signal at the input wavelength to a buffer pulsed signal at an adjustable wavelength and propagating the buffer pulsed signal within the cavity. The adjustable wavelength is set to a buffer wavelength different from the output wavelength and the buffer pulsed signal contains the information encoded in the input pulsed signal. The output wavelength is determined from the information encoded in the input pulsed signal. Upon determination of the output wavelength, the adjustable wavelength of the buffer pulsed signal is set to the output wavelength in order to; outputting the buffer pulsed signal at the output wavelength from the cavity.

摘要： An optical sensor is provided. The sensor includes an optical fiber having a free extremity on which a polymer layer is deposited normal to the longitudinal axis. A light source injects a analytical light beam in the fiber, which is reflected by the polymer layer. The reflected beam is analyzed by a spectrum analyzer, which determines the thickness of the polymer layer based on the Fabry-Perot effect. This thickness is related to a substance to be detected. An optical nose made from a plurality of such sensors is also provided, and may be used to detected a variety of substances.

摘要： A method for spatially controlling the period and amplitude of Bragg filters in an optical medium having a longitudinal axis that is sensitive to at least some wavelength of electromagnetic radiation. A phase mask of period .LAMBDA. is laid close to the optical medium at an angle .alpha. with respect to the longitudinal axis of the optical medium. A single beam of electromagnetic radiation is directed at an incidence angle .phi. with respect to normal incidence on the phase mask so that the radiation is diffracted, resulting in an interference pattern having a period P impinged into the optical medium so that the period P of the interference pattern may be altered by changing the incidence angle .phi. or the angle .alpha.. This method is simpler, more flexible and more suitable for mass production than existing methods.

摘要： The most common method of determining whether a breast contains cancerous tissue utilizes ionizing radiation, i.e. x-rays, which possible have tissue damaging properties. It has been found that lasers can be used as a light source in a breast tissue transillumination process. However, due to the high scattering coefficient (or diffusing properties) of breast tissue, it is not possible to obtain images having good resolution using classical transillumination techniques, even when a laser is used as the light source. When passing through a diffusing medium, a laser pulse decomposes into three classes of photons, namely ballistic, snake-like and diffuse photons. In most practical situations, the ballistic photon portion of a laser pulse, which travels in a straight line, does not pass through the tissue, i.e. only snake-like and diffuse photons pass through the tissue. It is proposed by this invention to use both the snake-like and diffuse photons in a method involving time gating and multiple field of view techniques to obtain a more precise evaluation of the scattering coefficients, i.e. a map of the interior of a region of the sample, whereby the presence (or absence) of tumors is determined. The use of multiple field of view and time gating techniques will yield a relatively clear picture of the structure of the tissue.
摘要翻译：确定乳房是否含有癌组织的最常见方法是利用可能具有组织损伤特性的电离辐射，即X射线。已经发现激光可以用作乳腺组织透照过程中的光源。然而，由于乳腺组织的高散射系数（或扩散性质），即使使用激光作为光源，也不可能使用经典的透照技术获得具有良好分辨率的图像。当通过漫射介质时，激光脉冲分解成三类光子，即弹道，蛇形和漫射光子。在大多数实际情况下，以直线行进的激光脉冲的弹道光子部分不通过组织，即仅蛇形扩散光子通过组织。本发明提出了在涉及时间门控和多视场技术的方法中使用蛇形和漫射光子两者以获得对散射系数的更精确的评估，即，样品，由此确定肿瘤的存在（或不存在）。使用多视野和时间选通技术将产生相对清晰的组织结构。
