Abstract:The challenge of capturing three-dimensional surface details using regular microscopy limits the ability to inspect complex structures, such as 3D printed microsystems and electronic circuit boards. Reflectance transformation imaging offers a promising solution to this issue. This thesis shows the development of a Raspberry Pi based microscope featuring the imaging technique, with the aim of enhancing the inspection of 3D printed structures and circuit boards for the Robotics and Mechatronics laboratory at the University of Twente. A rudimentary prototype from previous work served as the starting point of this project. After a complete redesign of the mechatronic and electronic systems, as well as the addition of key software features, the prototype has been transformed into a functional research tool. In addition to reflectance transformation imaging, the microscope now also features focus stacking and stereo photography, further extending its applications with this selection of imaging techniques. The result of this project not only demonstrates the success of reflectance transformation imaging for microscopy, it also highlights the viability of custom-built research equipment as powerful and accessible scientific tools.
