光学的一个主要应用是对物质的所有类型的结构、物理、化学和生物特征进行成像。多年来，基于光的大多数已知特性的技术已经被开发出来，用于远程获取有关这些特征的信息。它们包括编码在偏振中的自旋角动量，但还不包括编码在其螺旋光谱中的轨道角动量。在这里，我们提出了这种螺旋光谱的潜力。特别是，我们用几个典型的例子来说明光束的轨道角动量光谱如何能够用于对各种内在和外在特性进行成像，这些特性例如编码在相位和振幅梯度、位错或延迟中。（C）2005美国光学学会
A major application of optics is imaging all types of structural, physical, chemical and biological features of matter. Techniques based on most known properties of light have been developed over the years to remotely acquire information about such features. They include the spin angular momentum, encoded in the polarization, but not yet the orbital angular momentum encoded in its spiral spectrum. Here we put forward the potential of such spiral spectra. In particular, we use several canonical examples to show how the orbital angular momentum spectra of a light beam can be used to image a variety of intrinsic and extrinsic properties encoded, e. g., in phase and amplitude gradients, dislocations or delays.
