Abstract: An ultraprecision non-contact three-dimensional probing system based on a spherical capacitive plate has a probe (12) which comprises a spherical probing head (5), a stylus pipe (6), an active shielding pipe (8), a signal conducting rod (7), an insulating element (9), a stylus holder (10) and a probe body (11). The stylus pipe (6), the active shielding pipe (8) and the signal conducting rod (7) are coaxially assembled, and they are insulated against each other with the insulating element (9). The spherical probing head (5) is mounted at one end of the insulating element (9), and it has a spherical capacitive plate over its surface. The capacitive signal coming from the spherical capacitive plate is outputted through the signal conducting rod (7). The active shielding pipe (8) is driven by the signal converting and processing circuit (13) of the probing system to maintain equipotential with the signal conducting rod (7), and so the influence of parasitic capacitance and spatial electromagnetic interference can be eliminated.

Abstract: Photoelectric autocollimation methods and apparatuses based on beam drift compensation are provided. The methods and apparatuses can be used to achieve a high autocollimation angle measurement accuracy. The apparatuses includes an autocollimator, a measurement mirror (12a), a beam drift monitoring and separating unit, a beam steering device (8), and a data processing controller (7). The beam drift monitoring and separating unit generate a reference beam with the same drift as the measurement beam. The measurement beam carries both angular deflection information of the measurement mirror and the angular beam drift information, while the reference beam carries only the angular beam drift information. The data processing controller gives out a signal to the beam steering device in real-time according to the magnitude of drift of the reference beam, to compensate the drift of the measurement beam.

Abstract: A micro-cavity measuring equipment based on double optical fiber coupling includes a sight and transmitter, a controller, and a length measuring device. The equipment detects small changes in the position of an object with respect to a probe from a moment when the sight and transmitter starts working to another moment when the sight and transmitter stops working. The controller has a program to automatically control the whole measuring process. The measuring equipment is characterized in that the sight and transmitter consists of a laser unit, a data collecting and processing unit, and a double optical fiber coupling unit with its ends of incident and effluent optical fibers fixed on a coupler. A micro-cavity measuring method based on double optical fiber coupling consists of the following steps: inserting the probe into the micro-cavity and moving it in the measuring direction; sending signals to the length measuring device by the sight and transmitter to cause the length measuring device to record the corresponding position of the probe when the probe is contact with the sides of the micro-cavity; and then calculating the dimensions of the micro-cavity.

Abstract: A micro-cavity measuring method and equipment based on micro focal-length collimation are provided. The equipment can be used to measure irregular micro-cavities and “sub-macro” micro-cavities. Wherein a cylindrical or spherical lens with micro focal-length is combined with a fiber probe(11,12) to form a collimating and imaging optical system of a point light source(8), and the collimating and imaging optical system transforms the two or three dimensional movement of the fiber probe(11,12) into a change in image ultra-highly sensitively. A lot of advantages are obtained, i.e., micro measuring force, high aspect ratio, easy miniaturization, high resolution, simple construction and high speed.
