For some applications, it is required to periodically tune the optical wavelength of a laser source through a certain range. In some cases, one requires tuning through a relatively large range of e.g. 100 nm or more, and that quite rapidly, with a sweep frequency of tens or hundreds of kilohertz, sometimes even more than 1 MHz; conventional ...

Swept-source OCT - Retina Today

Swept-source OCT (SS-OCT; DRI-OCT, Topcon Japan) is the latest milestone in retinal and choroidal imaging. To overcome scattering by the RPE, which disabled visualization of deeper lying structures, a longer wavelength was adopted for this machine (1050 nm vs 840 nm in SD-OCT), and photodetectors instead of CCD cameras led to a further increase ...

light from the swept-source laser is delivered to the interferometer, where it splits into the reference and the sample arm. Light returned from the sample and refer-ence arms form an interferogram, which is detected by a balanced photodetector (Thorlabs, Inc.). The employ-ment of the balanced photodetector reduces the source

Swept-source OCTA instruments (Zeiss Plex Elite 9000 and Topcon Triton) use a tunable swept-source laser with a center wavelength of approximately 1,060 nm and a single photodiode detector. Compared with SD-OCTA, the longer wavelength used by SS-OCTA is safer, which means a higher laser power can be used.

swept-source laser | Photonics Dictionary® | Photonics ...

swept-source laser A type of laser in which the output wavelength is adjustable over a wide range of wavelengths. The laser is focused on a particular wavelength and is "swept" over a range of wavelengths. This is useful for rapidly capturing spectral data, such as in spectroscopy and (especially) in Fourier-domain optical coherence tomography.
