Dual camera sequencer for microsurgical documentation.

All currently available documentary formats have inherent compromises. The use of both video and 35-mm still photography seems to be a practical solution but introduces image quality loss (when using a beam splitter type of dual camera adapter) or increased complexity of operation and resultant surgeon distraction (when using a movable mirror type of dual camera adapter). An electronic sequencer was designed to simplify the operation of a movable mirror type of dual camera adapter, permitting the efficient production of high image quality video recordings and 35-mm slides.
