dc.descriptionFunding Information: KM and AK generated the concept. KM, as the main programmer, and AK wrote the scripts to realize the work. KM, AK and MR conducted DIC owing to Kim Widell at the Department of Mechanical Engineering, Aalto University. DL and JV conducted photoisomerization experiments and the RGB analysis, JT and LL carried out lap shear tests with the high-speed camera option. KM conducted the contact (wetting) angle measurements with Timo Kotilahti and MR. All the authors contributed to the manuscript writing while AK edited and finalized the manuscript.

dc.description.abstractWe present an affordable, yet accurate and modular camera system solution developed on Raspberry Pi 4/4 GB platform with Raspberry v2.x and HQ camera modules with 8 and 12.3 megapixels still resolutions, respectively. The system uses freely available Python scripts and libraries for digital image processing and non-contact optical measurements under MIT licenses as a contribution to the open-source initiative. Several investigations were conducted with the present system, which were two-dimensional (2D) digital image correlation (DIC) for the displacement and strain analysis, the kinetic analysis of the photoisomerization of the spiropyran (a model system for a time-dependent chemical reaction yielding molecules with differing color with respect to starting material) with time-lapse photography, lap shear tests with the assistance of high-speed image capturing and contact (wetting) angle measurements with still images and time-lapse photography. These studies show that the camera system, setups and scripts can be confidently integrated into the chemical, physical and mechanical tests.en
