    摘要: A method of imaging at least a part of an object. The method comprises splitting electro-magnetic radiation to first and second portions, propagating the first and second portions, spectrally dispersing the first portion toward the part and the second portion toward a reference element, combining between reflections of the spectrally dispersed first and second portions to produce an interference signal, capturing an image of the part from the interference, and adjusting at least one of a tilt of said image plane and a curvature of the image by changing a deviation between the phase of at least one spectral component of the first portion and the phase of at least one spectral component of the second portion.

    摘要: Exemplary apparatus and process can be provided for imaging information associated with at least one portion of a sample. For example, (i) first different wavelengths of at least one first electro-magnetic radiation can be provided within a first wavelength range provided on the portion of the sample so as to determine at least one first transverse location of the portion, and (ii) second different wavelengths of at least one second electro-magnetic radiation within a second wavelength range can be provided on the portion so as to determine at least one second transverse location of the portion. The first and second ranges can east partially overlap on the portion. Further, a relative phase between at least one third electro-magnetic radiation electro-magnetic radiation being returned from the sample and at least one fourth electro-magnetic radiation returned from a reference can be obtained to determine a relative depth location of the portion.

    摘要: Systems, arrangements and methods for obtaining three-dimensional imaging data are provided. For example, a broadband light source can provide a particular radiation. A first electro-magnetic radiation can be focused and diffracted, and then provided to at least one sample to generate a spectrally-encoded line. A second electro-magnetic radiation may be provided to a reference, which may include a double-pass rapidly-scanning optical delay, where the first and second electro-magnetic radiations can be based on the particular radiation. An interference between a third electro-magnetic radiation (associated with the first electro-magnetic radiation) and a fourth electro-magnetic radiation (associated with the second electro-magnetic radiation) can be detected. The spectrally-encoded line may be scanned over the sample in a direction approximately perpendicular to the line. Image data containing three-dimensional information can then be obtained based on the interference. The exemplary imaging methods and systems can be used in a small fiber optic or endoscopic probe.

    摘要: An adaptive pulse compressor is described, especially for use with ultrashort pulses, wherein the input pulses are modified in an iterative fashion, according to a feedback signal obtained from measurement of the output pulses. The feedback signal is programmed, by means of a programmable spatial light modulator, to allow for independent control of the individual spectral components of the incoming pulses, such that almost arbitrary phase functions can be realized to accomplish efficient compression. One of the main disadvantages associated with prior art pulse compressors, namely, the need for characterization of the uncompressed pulses, is thus eliminated. The compressor is thus capable of handling completely uncharacterized or partially characterized input pulses, or pulses from time varying sources.

    摘要: An apparatus and method according to an exemplary embodiment of to the present invention can provide imaging information associated with at least one portion of a sample. For example, at least two first different wavelengths of at least one first electro-magnetic radiation within a first wavelength range may be provided on the portion of the sample so as to determine at least one first transverse location of the portion. At least two second different wavelengths of at least one second electro-magnetic radiation may also be provided within a second wavelength range provided on the portion so as to determine at least one second transverse location of the portion. It is possible to obtain a relative phase between at least one third electro-magnetic radiation electro-magnetic radiation being returned from the sample and at least one fourth electro-magnetic radiation returned from a reference to determine a motion of the portion or of particles within or on the portion, whereas the motion is effectuated by at least one of a sound wave. Further, the imaging information of the portion can be provided based on the first transverse location, the second transverse location and the motion.
