Abstract
Apparatus, arrangement and method are provided for obtaining information associated with an anatomical structure or a sample using optical microscopy. For example, a radiation can be provided which includes at least one first electromagnetic radiation directed to be provided to an anatomical sample and at least one second electro-magnetic radiation directed to a reference. A wavelength of the radiation can vary over time, and the wavelength is shorter than approximately 1150 nm. An interference can be detected between at least one third radiation associated with the first radiation and at least one fourth radiation associated with the second radiation. At least one image corresponding to at least one portion of the sample can be generated using data associated with the interference. In addition, at least one source arrangement can be provided which is configured to provide an electromagnetic radiation which has a wavelength that varies over time. A period of a variation of the wavelength of the first electromagnetic radiation can be shorter than 1 millisecond, and the wavelength is shorter than approximately 1150 nm.
