Today at Intuitive Surgical we finished our investigation into the voltage, current, and temperature of a linear actuator while it is performing work onto differing amounts of mass. Afterwards me began our next and final project: creating a signal generator to facilitate an OCT (Optical Coherence Tomography) solution. OCT is a technique used for creating three dimensional images, such as of retina, by reflecting electromagnetic waves of different frequencies and measuring the phase shift. We also stress-tested some 3D prints in the Instron machine.
