Answer #1

2002-Time domain OCT(eg.Stratus)

  • 10 \mum axial resolution
  • scan velocity of 400A-scans/sec

2004-concept of spectral domain OCT introduced

2007-Spectral domain OCT

  • 1-15 \mum axial resolution
  • upto 52000A-scans/sec

Spectral-domain OCT (SD-OCT) achieves better signal-to-noise ratio (SNR), higher frame rates, and greater phase stability than predecessor time-domain OCT (TD-OCT) systems.

    Problem Solving: There’s No Place Like the Laser Lab The first optical maser demonstrated was the ruby laser (Theodor Mann, 1960). The optical gain medium is a “quasi-three-state” system. The system is called “quasi” because there are actually FOUR states total… but the two uppermost states both quickly decay into the intermediate/metastable state via mechanical losses of energy (aka. vibrations). a. Excitations into the two upper states occur for 400nm and 550nm light. The lasing wavelength is centered around 694.3nm....
