Question 1
OCT uses low-coherence interferometry to generate images. What property of light makes this technique possible?
Correct Answer:
Short coherence length from broadband light
Question 2
Time-domain OCT (TD-OCT) achieves depth scanning by moving the reference mirror. What is its primary speed limitation compared with spectral-domain OCT?
Correct Answer:
Reference-mirror motion
Question 3
Retinal SD-OCT commonly uses light near 840 nm. Why is this spectral region useful?
Correct Answer:
Retinal penetration with fine resolution
Question 4
Swept-source OCT (SS-OCT) typically uses a ~1050 nm center wavelength. What primary advantage does this confer over 840 nm SD-OCT?
Correct Answer:
Deeper signal penetration into the choroid
Question 5
In OCT terminology, a single depth profile of reflectivity along the beam axis is called:
Correct Answer:
A-scan
