Abstract: A procedure is performed on at least one section of an ocular component. At least one first electro-magnetic radiation is provided to the section so as to interact with at least one acoustic wave in the ocular component. At least one second electro-magnetic radiation is produced based on the interaction. Multiple portions of the second electromagnetic radiation are received. Each portion was emitted from a different corresponding segment of the section. A visco-elastic modulus of the section is monitored based on the multiple portions during the procedure. Feedback is applied to the procedure based at least in part on the monitored visco-elastic modulus, including at least one of: (1) guiding a trajectory of an incision based on different respective monitored values of visco-elastic modulus for the segments, or (2) determining a number of incisions to be made based on different respective monitored values of visco-elastic modulus for the segments.

Abstract: The present invention relates to a method and system for a label-free cell analysis based on Brillouin light scattering techniques. Combined with microfluidic technologies according to the present invention, Brillouin spectroscopy constitutes a powerful tool to analyze physical properties of cells in a contactless non-disturbing manner. Specifically, subcellular mechanical information can be obtained by analyzing the Brillouin spectrum of a cell. Furthermore, a novel configuration of Brillouin spectroscopy is provided to enable simultaneous analysis of multiple points in a cell sample.

Abstract: System, method, arrangement and non-transitory computer-accessible can be provided for, e.g., effecting refractive changes of the cornea by spatially-selective two-photon crosslinking of collagen fibers. For example, it is possible to obtain at least one property of at least one portion of the eye using at least one first arrangement. Based on the at least one property, data indicating a plan of affecting the portion(s) of the eye can be generated. Further, it is possible to control at least one electromagnetic-radiation-providing second arrangement to execute the plan and irradiate the at least one portion based on the plan. The irradiation can be selectively controlled to be delivered to at least one selective depth within the portion(s).

Abstract: Arrangements and methods can be provided for determining information associated with at least one section of at least one biological tissue. For example, it is possible to provide at least one first electro-magnetic radiation to the section(s) of the biological tissue(s) in vivo so as to interact with at least one acoustic wave in the biological tissue(s). At least one second electro-magnetic radiation can be produced based on the interaction. At least one portion of the at least one second electro-magnetic radiation can be received, and the information associated with the section(s) of the biological tissue(s) can be determined based on the portion of the second electromagnetic radiation(s).

Abstract: Exemplary embodiments of methods, arrangements and systems for obtaining information about a sample can be provided. For example, in one exemplary embodiment, it is possible to receive a first electro-magnetic radiation from a sample which is based on a second electro-magnetic radiation forwarded to the sample. The first electro-magnetic radiation may have a first frequency and the second electro-magnetic radiation may have a second frequency which is different from the first frequency. The difference between the first and second frequencies can be based on an acoustic wave inside the sample related to at least one characteristic of the sample. Further, it is possible to receive at least a portion of the first electromagnetic radiation and separate it into a particular finite number (N) of frequency component radiations. In addition, it is possible to receive a particular energy of more than 1/N of energy of the third electro-magnetic radiation, and generate information associated with the sample.

Abstract: An exemplary embodiment of apparatus and method to measure and filter the spectrum of electro-magnetic radiation using multiple dispersive elements, such as diffraction gratings or VIPA etalons, concatenated in a cross-axis orthogonal arrangement can be provided. For example, it is possible to receive at least one first electro-magnetic radiation and generate at least one second electro-magnetic radiation using at least one first spectral separating arrangement. A first spectrum of the second electro-magnetic radiation can be dispersed along at least one first dispersive axis with respect to a propagation direction of the second electro-magnetic radiation. In addition, it is possible to, using at least one second arrangement, receive the second electro-magnetic radiation and produce at least one third electromagnetic radiation having a second spectrum dispersed along at least one second dispersive axis with respect to a propagation direction of the third electromagnetic radiation.
