    摘要： Arrangements, apparatus and methods are provided according to exemplary embodiments of the present invention. In particular, at least one first electro-magnetic radiation may be received and at least one second electro-magnetic radiation within a solid angle may be forwarded to a sample. The second electro-magnetic radiation may be associated with the first electro-magnetic radiation. A plurality of third electro-magnetic radiations can be received from the sample which is associated with the second electro-magnetic radiation, and at least one portion of the third electro-magnetic radiation is provided outside a periphery of the solid angle. Signals associated with each of the third electro-magnetic radiations can be simultaneously detected, with the signals being associated with information for the sample at a plurality of depths thereof. The depths can be determined using at least one of the third electro-magnetic radiations without a need to utilize another one of the third electro-magnetic radiations.

    摘要： Apparatus and method for increasing the sensitivity in the detection of optical coherence tomography and low coherence interferometry (“LCI”) signals by detecting a parallel set of spectral bands, each band being a unique combination of optical frequencies. The LCI broad bandwidth source is split into N spectral bands. The N spectral bands are individually detected and processed to provide an increase in the signal-to-noise ratio by a factor of N. Each spectral band is detected by a separate photo detector and amplified. For each spectral band the signal is band pass filtered around the signal band by analog electronics and digitized, or, alternatively, the signal may be digitized and band pass filtered in software. As a consequence, the shot noise contribution to the signal is reduced by a factor equal to the number of spectral bands. The signal remains the same. The reduction of the shot noise increases the dynamic range and sensitivity of the system.

    摘要： An exemplary apparatus and/or an exemplary method can be provided using which, it is possible (e.g., with at least one first arrangement) to measure an amplitude and/or a phase of at least one electromagnetic radiation provided from a particular portion of a sample. Further, it is possible (e.g., using at least one second arrangement) to scan a location of the particular portion along a path from a first point of the sample to a second point of the sample. In addition, it is possible to control the scan (e.g., with the second arrangement) such that the scan may comprise at least one first segment having a positive velocity and at least one segment having a negative velocity. A first distance of the first segment and/or the second segment can be smaller than a second distance between the first and second points.
