摘要： A system for imaging a sample is disclosed. The system comprises a light source, a movable mirror, a photodetector, a first control unit and a second control unit. The light source generating a light beam and directing the light beam to the movable mirror which then deflects the light beam onto the sample. The photodetector detects light reflected from the sample. The first control unit steers the movable mirror according to position coordinates. The second control unit generates a data packet comprising the position coordinates and sending the data packet to the first control unit. The second control unit also generates trigger signals for the photodetector, the trigger signals being configured to trigger the photodetector to capture images corresponding to each of the position coordinates of the movable mirror. The first control unit and the second control unit communicate over Ethernet such that synchronization between the steering of the movable mirror and the triggering of the photodetector is enabled.

摘要： A high-dispersion retroreflector (1500) comprises filter glass transparent at least in near infra-red, IR, wavelengths and configured to cause differential dispersion of incident broadband low-coherent light in at least near infra-red, NIR wavelengths. The retroreflector may be used in a bulk glass differential dispersion interferometer assembly (1600) for extended depth imaging in optical coherence tomography, OCT. The interferometer assembly (1600) comprising an automated path length opto-mechanical assembly which includes a first, fixed, retroreflector (1604) located at one end of the optical-path; a second, adjustable, retroreflector (1602) co-located with a fixed high-dispersion retroreflector (1500) on a mount (1608) which is moveable to form an adjustable optical-path in the interferometer assembly (1600). The high-dispersion retroreflector (1500) comprising filter glass transparent at infra-red, IR, wavelengths is configured to cause differential dispersion at near infra-red, NIR wavelengths between broadband low-coherent incident light.

摘要： A computer-implemented image processing method for removing complex conjugate image data from image data in real-time using dispersion comprising receiving an image signal comprising image data including complex conjugate image data (902), performing baseline signal subtraction (906), resampling wavelength data to generate linear wavenumber image data (908, 910), processing the linear wavenumber image data to generate a complex conjugate resolved, CCR, result using at least one iteration of a CCR image processing algorithm (912), and computing a CCR image from the CCR result (914); and separating the resulting CCR image from the received OCT image data to remove the complex conjugate image data. The method may be performed in real-time and may use phase or magnitude data or a synthesis of the two when generating the image data from the CCR result.
