(a) Principle of moiré generated through coherent light diffracted through two periodic substrates. (b) Schematic of compact moiré system integrated with on chip cell culture.
Characteristic curve of optical moiré with respect to different grating periods. The grating periods (from top to bottom) are 6, 5, 4, and .
Representative images of optical moiré map (a) and unwrapped phase map (b) on the substrates for normal contracted VSMC. (c) Converted three-dimensional phase map from (b).
Optical moiré maps for ROCK silenced and control cells. The left (right) column is fringe patterns in direction parallel to the () direction of the substrate.
Strain/force plot as VSMC contracts in response to LPA. for control, ROCK-1 and ROCK-2 silenced cells, respectively.
