ST830O (ST850O) OCT spectrometer

ʻO ka wehewehe pōkole:

Hoʻolaʻa ʻia ka JINSP ST830/850O series spectrometer i ka ʻōnaehana OCT.He mea koʻikoʻi ia ma ka ʻōnaehana spectral domain OCT (SD-OCT), e hoʻoholo ana i nā hōʻailona hana koʻikoʻi e like me ka wikiwiki kiʻi a me ka ratio signal-to-noise (SNR fall-off) o ka ʻōnaehana OCT.
ʻO ST830/850O series spectrum e ʻike i ka hawewe nalu linear spatial dispersion ma o ka hoʻolālā ala optical kūikawā a ʻike pololei i ka laʻana o ka hawewe nalu ma ka lako.Hiki ke hoʻopili pololei ʻia ka spectrum interference i loaʻa i ka FFT me ka ʻole o ka hawewe resampling algorithm, kahi e hōʻemi nui ai i ka paʻakikī o ka hoʻoili ʻikepili a hoʻomaikaʻi i ka ratio signal-to-noise o ka ʻōnaehana.Eia kekahi, hoʻohana pū kēia huahana i ka volume phase holographic grating (VPH), he kiʻekiʻe ka maikaʻi a hiki ke hōʻea i ka 110dB signal-to-noise ratio i ka ʻōnaehana hoʻokolohua SD-OCT (7mW mana kumu kukui, 120kHz laina kiʻi wikiwiki), a loaʻa kiʻekiʻe. -ʻoi aku ka maikaʻi o OCT/OCTA i ke kiʻi olaola vivo.
