Binary-phase spatial filter for real-time swept-source optical coherence microscopy
DOI:10.1364/OL.32.002375.png)
摘要
En 中文
We report a novel scheme to optimize the focusing condition for real-time, swept-source optical coherence microscopy. The axial and lateral behaviors of four-zone binary-phase spatial filters are presented numerically A nearly constant axial intensity distribution along an extended depth of focus of 1.5 mm and a lateral resolution of 5 Am are experimentally verified. The A-line scan rate is up to 16 kHz, yielding a frame rate of 25 Hz and 640 lines per image. (C) 2007 Optical Society of America.
