Abstract—Accurately measuring cell stiffness is challenging
due to the invasiveness of traditional methods like atomic
force microscopy (AFM) and optical stretching. We introduce
a non-invasive off-axis system using holographic imaging and
acoustic stimulation. This system features an off-axis Mach-
Zehnder interferometer and bulk acoustic waves to capture
cell mechanics. It employs high-resolution components to create
detailed interferograms and allows continuous imaging of cell
deformation. Unlike conventional techniques, our method pro-
vides high-throughput, label-free measurements while preserving
cell integrity. Polyacrylamide beads are tested for high precision,
highlighting the potential of the system in early cancer detection,
disease monitoring, and mechanobiological research.
