Fourier-domain Optical Coherence Tomography (OCT) significantly enhances imaging capabilities compared to time-domain OCT. The primary advantage lies in its ability to obtain higher resolution images due to improved signal-to-noise ratio and better depth resolution. This technology utilizes Fourier transforms to analyze the light reflected from the retina, allowing for more detailed imaging of the ocular structures.

In addition to improved resolution, Fourier-domain OCT operates at a faster speed. This rapid acquisition rate enables the capturing of more data in a shorter time frame, resulting in a quicker examination process and less motion artifact, which can compromise image quality. This combination of higher resolution and faster operational efficiency makes Fourier-domain OCT a superior choice for retinal imaging.

Other options do not accurately reflect the capabilities of Fourier-domain OCT. The imaging process is not slower or less detailed; thus, any suggestion of lower performance is not aligned with the advancements in this technology. Similarly, Fourier-domain OCT does not specifically provide intermittent scanning capabilities nor is it limited to colored images only, emphasizing the importance of understanding the distinctions between different OCT technologies.
