    Abstract: In a minimally invasive surgical system, an image capture unit includes a prism assembly and sensor assembly. The prism assembly includes a beam splitter, while the sensor assembly includes coplanar image capture sensors. Each of the coplanar image capture sensors has a common front end optical structure, e.g., the optical structure distal to the image capture unit is the same for each of the sensors. A controller enhances images acquired by the coplanar image capture sensors. The enhanced images may include (a) visible images with enhanced feature definition, in which a particular feature in the scene is emphasized to the operator of minimally invasive surgical system; (b) images having increased image apparent resolution; (c) images having increased dynamic range; (d) images displayed in a way based on a pixel color component vector having three or more color components; and (e) images having extended depth of field.

    Abstract: A surgical instrument that includes a housing linkable with a manipulator arm of a robotic surgical system, a shaft coupled to the housing, a force transducer on a distal end of the shaft, and a plurality of fiber optic strain gauges on the force transducer is disclosed. The plurality of strain gauges are coupled to a fiber optic splitter or an arrayed waveguide grating (AWG) multiplexer, which can be coupled to a fiber optic connector. A wrist joint coupled to an end effector is coupled to a distal end of the force transducer. A robotic surgical manipulator that includes a base link coupled to a distal end of a manipulator positioning system, and a distal link with an instrument interface, and a fiber optic connector optically linkable to a surgical instrument. A method of passing data between an instrument and a manipulator via optical connectors is also provided.
