In this Letter, we derive a general criterion for the physical realizability of the differential Mueller matrix m of a depolarizing continuous medium. The criterion is based on checking the positive semidefiniteness of a 3×3 restriction of the coherency matrix of the G-symmetric component of m and turns out be a close analogue of the well-known criterion of Cloude for a Mueller matrix to be physically realizable. The related aspects of local and global, as well as Stokes and physical (or Cloude), realizabilities are discussed comparatively. The practical application of the criterion, in connection with the above types of realizabilities, is illustrated on experimental Mueller matrices from the literature.
在本信函中，我们推导了去极化连续介质的微分穆勒矩阵(m)物理可实现性的一般准则。该准则基于检查(m)的(G)对称分量的相干矩阵的(3×3)限制的半正定性，结果表明它是与著名的克劳德穆勒矩阵物理可实现性准则非常相似的准则。对局部和全局可实现性以及斯托克斯和物理（或克劳德）可实现性的相关方面进行了比较讨论。结合上述可实现性类型，通过文献中的实验穆勒矩阵说明了该准则的实际应用。
