Optical-enabled identification and interaction provide an integral link between the digital and physical realms. However, nowadays optic-encodings, predominantly reliant on light's intensity and wavelength, are hindered by environmental light interference and limited information capacity. The introduction of unusual polarization states, such as circular polarization-which is absent from ordinary surroundings-holds promise for higher-dimensional interaction. Here, we propose a circularly polarized optical mapper capable of generating high-entropy, noise-resistant keys, serving as a physical interface for unique interaction process between parties. To materialize this mapper, we developed an automated, in situ synthesis platform that facilitates the self-acting fabrication of robust, solid-state, chiral optical spin constrained assemblies. Our mappers, formed by randomized arrays of discrete assemblies, demonstrate near-theoretical performance in uniformity (0.4917), uniqueness (0.4968), and reliability (0.9355). By emitting high-dimensional spin-polarized light, our mappers enable both far-field readout and near-field authentication, with resistance to stray light interference, offering promising applications in the internet of things, augmented reality, and beyond.
光学识别与交互在数字领域和物理领域之间提供了不可或缺的联系。然而，如今主要依赖光的强度和波长的光学编码受到环境光干扰和有限信息容量的阻碍。引入诸如圆偏振等特殊偏振态（普通环境中不存在）有望实现更高维度的交互。在此，我们提出一种能够生成高熵、抗噪声密钥的圆偏振光学映射器，作为各方之间独特交互过程的物理接口。为了实现这种映射器，我们开发了一个自动化的原位合成平台，该平台有助于自主制造坚固的固态手性光学自旋受限组件。我们的映射器由离散组件的随机阵列形成，在均匀性（0.4917）、独特性（0.4968）和可靠性（0.9355）方面展现出接近理论的性能。通过发射高维自旋偏振光，我们的映射器实现了远场读取和近场认证，同时具备抗杂散光干扰能力，在物联网、增强现实及其他领域有着广阔的应用前景。
