Abstract
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.
