Abstract Multiplexing measurement has two well-known drawbacks – photon noise inapplicability and limited denoising capability – making it easily replaceable by a high-performance detector. Using a self-multiplexing with small-order coding matrix, we report a noise-type-free denoising measurement to address the limitations of photon noise and the denoising capability of the detector. Simulations and experiments show that multiplexing could break the limitations caused by detector capability, photon noise, and low light making it an unreplaceable unique solution in some applications.

突破基于Hadamard变换的复用限制

摘要 多路复用测量有两个众所周知的缺点——光子噪声不适用和有限的去噪能力——使其很容易被高性能探测器取代。使用具有小阶编码矩阵的自复用，我们报告了一种无噪声类型的去噪测量，以解决光子噪声和探测器去噪能力的局限性。模拟和实验表明，多路复用可以打破由探测器能力、光子噪声和低光引起的限制，使其成为某些应用中不可替代的独特解决方案。
