Fluorescence tomography is a well-established methodology able to provide structural and functional information on the measured object. At optical wavelengths, the unpredictable scattering of light is often considered a problem to overcome, rather than a feature to exploit. Advances in disordered photonics have shed new light on possibilities offered by opaque materials, treating them as autocorrelation lenses able to create images and focus light. In this Letter, we propose tomography through disorder, introducing a modified Fourier-slice theorem, the cornerstone of the computed tomography, aiming to reconstruct a three-dimensional fluorescent sample hidden behind an opaque curtain.
荧光层析成像技术是一种成熟的方法，能够提供被测量物体的结构和功能信息。在光学波长下，光的不可预测散射通常被认为是需要克服的问题，而不是需要利用的特征。无序光子学的进步为不透明材料提供的可能性带来了新的曙光，将其视为能够创建图像和聚焦光的自相关透镜。在这封信中，我们通过无序提出层析成像，引入了修正的傅里叶切片定理，这是计算机层析成像的基石，旨在重建隐藏在不透明幕后面的三维荧光样本。
