Optical imaging of biological systems has undergone spectacular development in recent years, producing a quantity and a quality of information that, just twenty years ago, could only be dreamed of by physicists, biologists and physicians.

Unconventional imaging systems provide access to physical quantities – phase, absorption, optical index, the polarization property of a wave or the chemical composition of an object – not accessible to conventional measurement systems. To achieve this, these systems use special optical setups and specific digital image processing to reconstruct physical quantities. This field is also known as computational imaging.

This book presents various non-conventional imaging modalities developed for the biomedical field: wave front analysis imaging, digital holography/tomography, optical nanoscopy, endoscopy and singlesensor imaging. Experimental setups and reconstruction algorithms are presented for each modality.

近年来，光学成像在生物系统中的应用发展迅猛，产生了物理量、质量和信息的数量和质量，这些信息二十年前只存在于物理学家、生物学家和医生的梦想中。 非传统成像系统提供了访问物理性质——相位、吸收、光的折射率以及波的偏振特性或物体的化学组成——的方法，这在传统的测量系统中是无法触及的。为了实现这一点，这些系统使用了特殊的光学装置和特定的数字图像处理技术来重建物理性质。这一领域也被称为计算成像。 本书介绍了为生物医学领域开发的各种非传统成像模式：波前分析成像、数字化全息术/断层扫描、光子显微镜、内窥技术和单像素成像。每种模式都提供了实验设置和重建算法。
