Methods, systems and devices for optical structural health monitoring of a subject, including the utilization of pointillism to provide a design or painting of the surface of the structure to be monitored, which also serves as a mechanism for conducting SHM, implementing digital image correlation (DIC) by applying a pattern comprising a random dot pattern and/or codes. The subject is imaged using imaging equipment to capture images of the pattern. For some applications, the captured images of the pattern and codes are stored in a CAD file that represents the subject or portion thereof to which the pattern and codes are applied, and includes the locations of the pattern and codes. Indicia applied to a structure may be applied using a paintjet or inkjet, or robotic mechanism, while some applications implement pre-patterning of a composite sheet that is used to form the structure.
