Spectroscopic spectral-domain optical coherence microscopy.
The spectroscopic content within optical coherence tomography (OCT) data can provide a wealth of information. Spectroscopic OCT methods are frequently limited by time-frequency trade-offs that limit high spectral and spatial resolution simultaneously. We present spectroscopic spectral-domain optical coherence microscopy performed with a multimodality microscope. Restricting the spatial extent o...
متن کاملIn vivo human retinal imaging by ultrahigh-speed spectral domain optical coherence tomography.
An ultrahigh-speed spectral domain optical coherence tomography (SD-OCT) system is presented that achieves acquisition rates of 29,300 depth profiles/s. The sensitivity of SD-OCT and time domain OCT (TD-OCT) are experimentally compared, demonstrating a 21.7-dB improvement of SD-OCT over TD-OCT. In vivo images of the human retina are presented, demonstrating the ability to acquire high-quality s...
متن کاملUltrahigh-resolution high-speed retinal imaging using spectral-domain optical coherence tomography.
We present the first ultrahigh-resolution optical coherence tomography (OCT) structural intensity images and movies of the human retina in vivo at 29.3 frames per second with 500 A-lines per frame. Data was acquired at a continuous rate of 29,300 spectra per second with a 98% duty cycle. Two consecutive spectra were coherently summed to improve sensitivity, resulting in an effective rate of 14,...
متن کاملQuantitative phase imaging with spectral-domain optical coherence phase microscopy
Spectral domain optical coherence phase microscopy provides high resolution quantitative phase measurement. Using a common path Fourier domain optical coherence tomography system, this technique is capable of excellent phase stability of less than 1 milliradian and high imaging speed of up to several hundred KHz Aline rate. The limitation of 2π ambiguity restriction can be overcome by the use o...
متن کاملSpectral-domain optical coherence phase and multiphoton microscopy.
We describe simultaneous quantitative phase contrast and multiphoton fluorescence imaging by combined spectral-domain optical coherence phase and multiphoton microscopy. The instrument employs two light sources for efficient optical coherence microscopic and multiphoton imaging and can generate structural and functional images of transparent specimens in the epidirection. Phase contrast imaging...
