Standard image sensors only detect light intensity, missing the critical “delay” or phase information—the Optical Path Difference (OPD)—created when light interacts with a sample. shinephi’s technology utilizes Lateral-shear Interferometric Microscopy (LIM) to convert these invisible phase delays into measurable intensity signals. By splitting and overlaying light beams, our system captures topography and refractive index changes with nanometric precision, transforming standard light into high-fidelity quantitative data.
