Optical path difference active control mechanism
Neumanová, Anna ; Šulc, Václav (referee) ; Špaček, Matěj (advisor)
There is a long-term development of the Coherence-Controlled Holographic Microscope (CCHM) ongoing in the Laboratory of Experimental Biophotonics at the Faculty of Mechanical Engineering in Brno. A mechanism for active control of the optical path length needs to be implemented in the imaging setup of the microscope. The reason is the high sensitivity of the microscope to the optical path difference of~its~optical branches. Therefore, the mechanism must meet the high-resolution requirements. First, suitable mechanisms for this application are compared. Based on the research, three conceptual designs are presented. For the selected design, a complete technical solution is elaborated. The mechanism is then fabricated, assembled and tested in terms of its motion characteristics.
