Line imaging of fluorescent and absorptive objects with a single-pixel imaging technique that acquires one-dimensional cross-sections through a sample by imposing a spatially-varying amplitude modulation on the probing beam is demonstrated. The fluorophore concentration or absorber distribution of the sample is directly mapped to modulation frequency components of the spatially-integrated temporal signal. Time-domain signals are obtained from a single photodiode, with object spatial frequency correlation encoded in time-domain bursts in the electronic signal from the photodiode.
展示了一种单像素成像技术对荧光和吸收性物体的线成像，该技术通过在探测光束上施加空间变化的幅度调制来获取穿过样品的一维横截面。样品的荧光团浓度或吸收体分布直接映射到空间积分时间信号的调制频率分量上。时域信号从单个光电二极管获得，物体空间频率相关性编码在来自光电二极管的电子信号中的时域脉冲串中。
