    摘要： Exemplary system, method and computer accessible medium are provided for determining at least one characteristic of a target object located behind or within a medium. For example, it is possible to identify a reference object that is located behind or within the medium. The target object and the reference object can be irradiated via a surface of the medium using at least one electromagnetic wave. At least one acoustic signal provided from an irradiated tissue volume that is responsive to the electromagnetic wave(s) can be measured. Calibration information can be obtained from the acoustic signal measured from the reference object based on at least one known property of the reference object. Then, the characteristic(s) of the target object can be determined based on the calibration information and the acoustic signal from the target object.

    摘要： In some embodiments, systems, methods, and media for multiple reference arm spectral domain optical coherence tomography are provided which, in some embodiments, includes: a sample arm coupled to a light source; a first reference arm having a first path length; a second reference arm having a longer second path length; a first optical coupler that combines light from the sample arm and the first reference arm; a second coupler that combines light from the sample arm and the second reference arm; and an optical switch comprising: a first input port coupled to the first optical coupler; a second input coupled to the second coupler via an optical waveguide that induces a delay at least equal to an acquisition time of an image sensor; and an output coupled to the image sensor.

    摘要： Exemplary method and apparatus for diagnosing or characterizing an inflammation within an anatomical structure can be provided. For example, using at least one source arrangement, it is possible to provide at least one first electro-magnetic radiation to the anatomical structure at at least one first wavelength in vivo. With at least one detector arrangement, it is possible to detect at least one second electro-magnetic radiation at at least one second wavelength provided from the anatomical structure. The second radiation can be associated with the first radiation, and the first wavelength can be shorter than the second wavelength. The second radiation can be provided from the anatomical structure due to at least one change in the anatomical structure caused by the inflammation without providing an artificial fluorescence substance. At least one computer arrangement can be used to determine at least one characteristic of the structure based on the second radiation to diagnose or characterize the inflammation within the anatomical structure.

    摘要： A probe can be provided having a grating adapted for color spectrally encoded imaging. The probe can include a waveguide configuration, a light focusing configuration, and a grating configuration that can have a first grating pattern and a second grating pattern. The waveguide configuration can be configured and/or structured to cause to propagate a light having a first wavelength and a light having a second wavelength to propagate from the waveguide component, and the light focusing and waveguide configurations can provide the light to be incident on the grating configuration. The grating configuration can be configured and arranged such that the light having the first wavelength is diffracted by the first grating pattern to substantially the same location as the light having the second wavelength is diffracted by the second grating pattern.

    摘要： Exemplary apparatus for coupling to a probe and providing information regarding at least one structure can be provided. For example, the apparatus can include an electronics arrangement which is configured to obtain the information and transmit the information wirelessly, and a structural connection configuration which is structured and configured to be attached to the probe. The electronics arrangement can include a detector arrangement which is configured to detect at least one return radiation from at least one portion of at least one sample based on the predetermined patterns, and provide the data for the portion(s) based on the return radiation(s). In addition, a computer arrangement can be provided which is configured to generate the information with includes image data for the portion(s) as a function of the data and prior knowledge of the predetermined patterns.
