An optical imaging system, for example, for a surgical microscope (100) has a beam deflecting unit in order to cast light rays out of an object region (112) into an image plane (104) with an optical beam path. An optical phase plate (107) is mounted in the optical beam path. In the optical imaging system, a unit for generating a geometric image of the image plane is provided, for example, an ocular unit (105). The optical phase plate (107) is arranged on the end of the objective lens (101) facing away from the object or is arranged in a region of the optical imaging system in which the beam path is parallel.

The objective is to ensure the inflator yields a force sufficient to hold the shunt, prevent the shunt from coming off the inflator, reduce the force required to insert the shunt into the socket, and enhance the workability of assembling the shunt into the socket. The shunt body is provided with a short-circuit piece which short-circuits the pair of pins of the squib, and the shunt body is provided with a protrusion being formed of a flexible material, the root end of the protrusion is provided on the outer face of the shunt body, the protrusion extends from the root end thereof in a direction tilting toward the outside from the shunt body at an angle within 90 degrees to a direction being parallel to the central axis of the shunt body and heading toward the top thereof, and it is arranged that when the top end of the protrusion is pushed toward the connection hole of the shunt body, the protrusion will undergo deformation by bending, and when the shunt body fits into the socket, the protrusion will restitute to protrude in the fitting concave.

A single camera acquires an input image of a scene as observed in an array of spheres, wherein pixels in the input image corresponding to each sphere form a sphere image. A set of virtual cameras are defined for each sphere on a line joining a center of the sphere and a center of projection of the camera, wherein each virtual camera has a different virtual viewpoint and an associated cone of rays, appearing as a circle of pixels on its virtual image plane. A projective texture mapping of each sphere image is applied to all of the virtual cameras on the virtual image plane to produce a virtual camera image comprising circle of pixels. Each virtual camera image for each sphere is then projected to a refocusing geometry using a refocus viewpoint to produce a wide-angle lightfield view, which are averaged to produce a refocused wide-angle image.

A connector has female and male housings (10, 60). A cam pin (63) projects from the male housing (60), and a jaw (65) bulges out at the end of the cam pin (63). A lever (30) is mounted to the female housing (10), and has a cam groove (33) for engaging the cam pin (63). A step (38, 39) in the cam groove (33) defines an accommodating portion (42) for the jaw (65). The depth of the accommodation portion (42) is larger near the entrance of the cam groove (33) so that the jaw (65) initially is accommodated loosely. However the depth of the accommodating portion (42) is smaller towards the back of the cam groove (33) to prevent loose movements.
