A 3D camera and a photographing method thereof are provided. The 3D camera includes an imagephotographing unit and an imagephotographing unit in the same optical system and a processing system that processes data of the imagephotographing unit and the imagephotographing unit. The processing system includes a control unit that controls image photographing by the imagephotographing unit and the imagephotographing unit, a recording and storage unit that performs processing on the control unit, and a 3D coordinate calculation unit that performs calculation on the recording and storage unit. 3D coordinates of an object point in 3D space or all space object points constituting a 3D object directly facing the camera are calculated by simultaneously photographing one or more pairs of images for the object point in the 3D space or all space object points constituting the 3D object.

Three-dimensional space camera and photographing method therefor

A tool for installation and removal of a connector of a gas-insulated switchgear termination includes a housing defining an operation chamber therein, a mounting assembly selectively disposed in the operation chamber of the housing and adapted for securely installing a sleeve member of a gas-insulated switchgear termination on a conical connector member of the gas-insulated switchgear termination or removing the sleeve member securely sleeved on the conical connector member from the conical connector member, an actuator assembly adapted for actuating motion of the mounting assembly, and a friction reducing assembly adapted for reducing friction and resistance occurring during the motion of the mounting assembly.

Tool for installation and/or removal of connector or gas-insulated switchgear termination

An apparatus for monitoring an input optical signal at a plurality of distinct optical frequencies is disclosed wherein a demultiplexing arrayed waveguide grating (AWG) having a plurality of M&#x3e;1 Vernier input ports is disposed between an optical switch and a photodiode array coupled to the output ports of the AWG. In operation, the optical switch sequentially provides the input optical signal into each of the Vernier ports, and signals detected by photodiodes are stored in a memory unit. The apparatus is capable of monitoring the input optical signal with a frequency step which is M times smaller than a frequency spacing between the AWG transmission bands, and obtain M frequency-resolved readings from each photodiode.
