Exemplary embodiments of systems and methods can be provided which can generate data associated with at least one portion of a sample. For example, at least one first radiation can be forwarded to the portion through at least one optical arrangement. At least one second radiation can be received from the portion which is based on the first radiation. Based on an interaction between the optical arrangement and the first radiation and/or the second radiation, the optical arrangement can have a first transfer function. Further, it is possible to forward at least one third radiation to the portion through such optical arrangement (or through another optical arrangement), and receive at least one fourth radiation from the portion which is based on the third radiation. Based on an interaction between the optical arrangement (or the other optical arrangement) and the third radiation and/or the fourth radiation, the optical arrangement (or the other optical arrangement) can have a second transfer function. The first transfer function can be at least partially different from the second transfer function. The data can be generated based on the second and fourth radiations.

Exemplary embodiments of probes, apparatus, systems and methods can be provided which provide at least one electro-magnetic radiation to at least one sample. For example, a plurality of axicon lenses can be provided which are configured to provide the electro-magnetic radiation(s) having at least partially annulus shape. In addition or alternatively, at least one optical arrangement can be provided which is configured to forward at least one radiation to the sample therethrough having at least partially circularly-symmetric pattern. For example, at least one first portion of the radiation transmitted through a circular section of the pattern can have an optical path-length that is different from an optical path-length of at least one second portion of the radiation transmitted through at least one other section of the pattern.

Exemplary apparatus and method can be provided for controlling at least one electro-magnetic radiation. For example, it is possible to rotate and/or translate at least one optical waveguide. At least one of the optical waveguide(s) can receive a first radiation at a first wavelength and transmit the first radiation to at least one sample. Such optical waveguide and/or another optical waveguide may receive a second radiation at a second wavelength that is different from the first wavelength. For example, the second radiation may be produced based on an inelastic scattering of the first radiation. In addition, exemplary apparatus and method can be provided which can also be used to receive data associated with the second radiation, determine at least one characteristic of the at least one sample based on the data, and generate the image and/or the map of a portion of the arterial sample based on the at least one characteristic. Further, exemplary computer-accessible medium can be provided which includes a software arrangement thereon. When a processing arrangement executes the software arrangement, the processing arrangement is configured to modify at least one characteristic of an arrangement using certain procedures. These exemplary procedures include simulating at least one electro-magnetic radiation provided into and out of the arrangement, simulating an inelastic scattering radiation from at least one simulated sample, receiving the simulated inelastic scattering radiation into and out of the simulated arrangement, and determining a simulated characteristic of the simulated arrangement as a function of the simulated inelastic scattering radiation.

Exemplary embodiments of apparatus, method and computer accessible medium can be provided which can facilitate a determination of at least one characteristic of a structure. For example, it is possible to use at least one first arrangement which can be structured to provide at least one first transmitted radiation along a first axis and at least one second transmitted radiation along a second axis. The first and second transmitted radiations can impact the structure and generate respective first and second returned radiation. The first and second axis can be provided at a predetermined angle with respect with one another which is greater than 0. Further, at least one second arrangement can be provided which can be configured to receive data associated with the first and second returned radiations, and determine at least one relative velocity between the structure and the first arrangement along the first and second axes.
摘要:
An apparatus and method are provided. In particular, at least one first electro-magnetic radiation may be provided to a sample and at least one second electro-magnetic radiation can be provided to a non-reflective reference. A frequency of the first and/or second radiations varies over time. An interference is detected between at least one third radiation associated with the first radiation and at least one fourth radiation associated with the second radiation. Alternatively, the first electro-magnetic radiation and/or second electro-magnetic radiation have a spectrum which changes over time. The spectrum may contain multiple frequencies at a particular time. In addition, it is possible to detect the interference signal between the third radiation and the fourth radiation in a first polarization state. Further, it may be preferable to detect a further interference signal between the third and fourth radiations in a second polarization state which is different from the first polarization state. The first and/or second electro-magnetic radiations may have a spectrum whose mean frequency changes substantially continuously over time at a tuning speed that is greater than 100 Tera Hertz per millisecond.

For example, the portion can have an area greater than about 1 mm2, and the image can have a resolution a transverse resolution that is below about 10 μm. For example, light can be scanned over such portion so as to generate first information which is related to the portion, where the light may be provided through a diffraction arrangement to generate a spectrally dispersed line. Method, apparatus and arrangement according to a further exemplary embodiment of the present invention can be provided for positioning a radiation or optical beam within an anatomical structure based on signals generated by scanning a portion of the structure using the same or a different beam.
