AI 中文摘要

有限记忆光学示踪剂可通过其先前经历的激发来编码输运特性。利用发射体中可激发的长寿命电子态群体所承载的这种记忆特征,无需瞬时定位评估即可确定其输运特性。在此,我们阐述了这一原理,用于监测从条件输运历史的输运历史积分中提取的随机输运。在结构化照明下,该历史产生可测量的传递函数响应,从中无需时间分辨采集即可重建标量和张量扩散。Fisher信息分析确定了最佳工作区间,并给出了标量和张量重建精度的第一性原理、无参数预测,与独立蒙特卡洛模拟定量一致。这些结果确立了有限光学记忆作为随机输运成像的一般原理。

英文摘要

Finite-memory optical tracers can encode transport properties through their previously experienced excitation. Using such memory features, harboured in the population of excitable long-lived electronic states within the emitters, instantaneous localization assessments are not needed to determine their transport properties. Here we formulate this principle for monitoring of stochastic transport extracted from transport-history integral over conditional transport histories. Under structured illumination, this history yields a measurable transfer-function response from which scalar and tensor diffusion are reconstructed without time-resolved acquisition. Fisher-information analysis identifies the optimal operating regime and yields first-principles, parameter-free predictions of scalar and tensor reconstruction precision, in quantitative agreement with independent Monte Carlo simulations. These results establish finite optical memory as a general principle for stochastic transport imaging.
