    摘要: A compliant structure which includes a means for sensing translation and rotation of a top plate is disclosed. The structure is composed of a base plate and three supporting legs. The legs are compliant. The deflections of the structure are substantially in a plane and the translation and twist of the top platform may be measured by the gimbaled sensor assembly attached to one of the legs.

    摘要: An interactive, autostereoscopic system for displaying an object in 3D includes a mirror configured to spin around a vertical axis when actuated by a motor, a high speed video projector, and a processing system including a graphics card interfaced to the video projector. An anisotropic reflector is bonded onto an inclined surface of the mirror. The video projector projects video signals of the object from the projector onto the inclined surface of the mirror while the mirror is spinning, so that light rays representing the video signals are redirected toward a field of view of a 360 degree range. The processing system renders the redirected light rays so as to interactively generate a horizontal-parallax 3D display of the object. Vertical parallax can be included in the display by adjusting vertically the displayed views of the object, in response to tracking of viewer motion by a tracking system.

    摘要: 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.

    摘要: A minimally invasive surgical includes a scene anti-bloom process that allows switching between imaging modes on a stereoscopic display without causing a surgeon to look-away or being momentarily distracted by sudden changes in overall scene luminance. The process receives a switch from a first imaging mode to a second imaging mode. An overall scene luminance of a scene in the first imaging mode is less than an overall scene luminance of a scene in the second imaging mode. The process delays the switch to the second imaging mode until after an illumination output level of a visible illumination source has changed to a higher output level, and then switches to the second imaging mode.

    摘要: In one embodiment of the invention, an apparatus includes a display device. The display device displays a desaturated image of tissue captured in the visible electro-magnetic (EM) spectrum from a body cavity; and a first color enhanced image combined with the desaturated image. The first color enhanced image represents the first data captured from the body cavity outside the visible electromagnetic spectrum. The relative brightness between the desaturated image and the first color enhanced image is set to emphasize the first data over the tissue captured in the visible electromagnetic spectrum to provide improved information content.
