    摘要： An and source arrangement for filtering an electromagnetic radiation can be provided which may include at least one spectral separating arrangement (200) configured to physically separate one or more components (320, 340) of the electromagnetic radiation based on a frequency of the electromagnetic radiation. The apparatus and source arrangement may also have at least one continuously rotating optical arrangement, e.g., a spinning reflector disk scanner (500), which is configure to receive at least one signal that is associated with the one or more components (320, 340). Further, the apparatus and source arrangement can include at least one beam selecting configured to receive the signal. Rotating disk (500) may comprise reflecting patterns (520) to generate a wavelength scan depending on the rotation frequency of the disk (500).

    摘要： Arrangements and methods are provided for obtaining data associated with a sample. For example, at least one first electro-magnetic radiation can be provided to a sample and at least one second electro-magnetic radiation can be provided to a reference (e.g., a non-reflective reference). A frequency of such radiation(s) can repetitively vary over time with a first characteristic period. In addition, a polarization state of the first electro-magnetic radiation, the second electro-magnetic radiation, a third electro-magnetic radiation (associated with the first radiation) or a fourth electro-magnetic radiation (associated with the second radiation) can repetitively vary over time with a second characteristic period which is shorter than the first period. The data for imaging at least one portion of the sample can be provided as a function of the polarization state. In addition or alternatively, the third and fourth electro-magnetic radiations can be combined so as to determine an axial reflectance profile of at least one portion of the sample.

    摘要： An apparatus for filtering an electromagnetic radiation comprises at least one spectral separating arrangement (4) configured to angularly separate one or more components of the electromagnetic radiation based on a frequency of the electromagnetic radiation. The apparatus also comprises at least one angularly deflecting optical arrangement (24) that includes a pivot point, and is configured to receive the one or more components of the electromagnetic radiation to generate at least one signal associated with the one or more components. The apparatus further comprises at least one optical imaging arrangement (20, 22) configured to directly receive from the spectral separating arrangement the one or more components of the electromagnetic radiation, and generate an image of one or more dispersive elements associated with the one or more components toward the deflecting optical arrangement.
