A display unit which is electronically connected to a body to display data, and has an antenna electronically connected thereto for transferring data. The body has a first element, a second element, an index unit and an intermediate element. The second element is coupled to the first element along a first axis, and the index unit is coupled to the second element along a second axis through the intermediate element and electronically connected to the display unit. The index unit is electronically connected to the display unit and provides a first index port and a second index port, allowing different function modes, respectively.

An interference apparatus is disclosed wherein the high-visibility quadrature interference signals are obtained by making a pair of polarization beamsplitter, a 45-degree oriented quarter-waveplate and four light-beam detected photodiodes. A three-dimensional interference optical configuration is made. The test-surface light beam and reference light beams are traveled on this optical configuration. The test-surface light beam and reference light beams have orthogonally linearly polarization state with each other. After they pass through the quarter-waveplate, one right circularly polarized light beam and one left circularly polarized light beam are produced. The vector sum of these two circularly polarized light beams is again a linearly polarized light beam which is then divided into two light beams by a non-polarization beamsplitter. A pair of polarization beamsplitters, whose axes are 45 degrees apart, are utilized to create the 90 degrees phase difference of the light beam intensity signal measured at the photodiodes.
