Author Correction: Single-shot quantitative phase-fluorescence imaging using cross-grating wavefront microscopy

In Figure 4, the OPD scale bar was incorrect in panel (a). The original Figure 4 and accompanying legend appear below. Figure 4 CGM images on various types of live cells. ( a ) U2OS cells, with mitochondria labelled with MitoTracker dyes. Fluorescence and OPD images are displayed, along with a mixed image of the two. ( b ) Same as ( a ), with COS-7 cells. ( c ) Same as ( b ), with a close up on mitochondria. ( d ) Same as ( c ) with Escherichia coli (K12) bacteria, labelled with SYTO 9 stain. Images acquired with \(132\times\) magnification, 1.3 NA.
