In embodiments using a subsection of the data set, this can reduce processing time, and can provide lower axial resolution, which may be useful for a variety of feedback purposes.
Homodyne/heterodyne filtering can also have applications in general image processing in the Fourier domain variants of Optical Coherence Tomography where the large number of post-processing and/or real-time calculations (including interpolation, digital dispersion compensation, spectral shaping etc.) may encumber the computational efficiency of the system.
Though not limited to this case, such embodiments may be useful in situations where imaging is targeting a subsection of the full depth of field.
In some embodiments, it is beneficial to obtain the homodyne waveform(s) by measuring a real interferogram when an interface is at specific depth(s) in the image.
The complex homodyne waveform(s) may be obtained by shifting the interface optomechanically by moving the interface, optically with phase shifting optics and/or through digital processing, which may use Hilbert transforms and other methods.
