In this thesis, we have two topics. Firstly, we developed a spectral-domain optical coherence tomography system to obtain biological tissue scattering, the system uses coherence gating of backscattered light for tomographic imaing of tissue structure. Variation in tissue scattering due to in-homogeneities in the optical index of refraction provide imaing contrast. Finally, we have successfully used Doppler optical micro-angiography (DOMAG) to image phantom flow and skin blood perfusion in mice. We then conduct in vivo experiments on a mouse brain to demonstrate that DOMAG is capable of quantifying the blood flow within cerebrovascular network.頻域式光學同調斷層攝影系統都普勒光學微血管攝影術Spectral-domain optical coherence tomography systemDoppler optical micro-angiography
