Abstract: A compact conical diffraction Littrow spectrometer is disclosed. The distortion of the conically diffracted spectral component beams is compensated and as a result, the diffracted spectral beams can still be focused into a substantially straight line to shine onto a detector array. A spectral domain optical coherence tomography (SD-OCT) system incorporating a Littrow spectrometer or a spectrometer having one or more shared focusing element(s) and an SD-OCT system incorporating a spectrometer that is substantially polarization independent are also disclosed.

Abstract: Systems and methods for expanding the field-of-view ofophthalmic scanning devices are presented. An ophthalmic scanning device is designed such that the pivot point of the scanning optics is maintained at a fixed location in the pupil while the scanning optics are rotated about the eye to obtain imaging data over an increased field-of-view than can be achieved by the scanning optics alone. The rotation can be achieved using a singular rotational motion of the scanning optics about a rotational axes coincident with the scanning pivot point or can be achieved using a combination of rotational motion with a second motion either rotational or translational to maintain the scanning pivot point at the fixed location. Embodiments related to optical coherence tomography and scanning laser ophthalmoscopy are described.

Abstract: A spectral-domain optical coherence tomography system using a cross-dispersed spectrometer is disclosed. The interfered optical signal is dispersed by a grating into several orders of diffraction, and these orders of diffraction are separated by an additional dispersive optical element. The spectral interferogram is recorded by a set of linear detector arrays, or by a two-dimensional detector array.
