Abstract
Following general single-channel optimization, input channels are typically treated as independent elements in the transmission matrix. This paper presents compelling evidence of a remarkable correlation between input channels due to the continuous distribution of optimal phase masks. This correlation challenges the previous notion that single-channel optimization is highly sensitive to wavefront changes, such that an obvious focal point still forms even when the optimal phase mask is completely refreshed. Further, this correlation significantly enhances the focus light intensity when the optimized wavefront is seriously impaired. The discovery of this correlation will offer new insights into the physics of a transmission matrix.
