    Abstract: 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.

    Abstract: Speckle, a factor reducing image quality in optical coherence tomography ('OCT'), can limit the ability to identify cellular structures that are important for the diagnosis of a variety of diseases. The present invention allows for an implementation of an angular compounding, angular compounding by path length encoding ('ACPE') for reducing speckle in OCT images. By averaging images obtained at different incident angles, with each image encoded by path length, ACPE maintains high-speed image acquisition and implements minimal modifications to OCT probe optics. ACPE images obtained from tissue phantoms and human skin in vivo demonstrate a qualitative improvement over traditional OCT and an increased signal-to-noise ratio ('SNR'). Accordingly, apparatus probe catheter, and method are provided for irradiating a sample. In particular, an interferometer (5) may forward forwarding an electromagnetic radiation (10). In addition, a sample arm may receive the electromagnetic radiation, and can include an arrangement (20) which facilitates a production of at least two radiations (30, 40) from the electromagnetic radiation so as to irradiate the sample. Such arrangement can be configured to delay a first radiation of the at least two radiations with respect to a second radiation of the at least two radiations.

    Abstract: Exemplary embodiments of apparatus, method and system for determining a position on or in a biological tissue can be provided. For example, using such exemplary embodiment, it is possible to control the focus of an optical imaging probe. In another exemplary embodiment, it is possible to implement a marking apparatus together with or into an optical imaging probe. According to one exemplary embodiment, it is possible (using one or more arrangements) to receive information associated with at least one image of at least one portion of the biological tissue obtained using an optical imaging technique. Further, it is possible to, based on the information, cause a visible change on or in at least location of the portion(s) using at least one electro-magnetic radiation.
