We report laser Doppler ophthalmoscopic fundus imaging in the rat eye with near-IR heterodyne holography. Sequential sampling of the beat of the reflected radiation against a frequency-shifted optical local oscillator is made onto an array detector. Wide-field maps of fluctuation spectra in the 10 Hz to 25 kHz band exhibit angiographic contrasts in the retinal vascular tree without requirement of an exogenous marker.
我们报告了使用近红外外差全息术的大鼠眼激光多普勒眼底图像。通过对阵列探测器进行反射辐射与频移光学本振的拍频的连续采样来实现。在 10 Hz 至 25 kHz 频段内的波动光谱的宽场图谱显示了视网膜血管树中的血管造影对比度,而无需外源性标记物。
