Development of Ultra Precision Machining with High Positioning Resolution

INSTRUCTIONS The technology for ultra-precision machining has been developed rapidly and steadily. In recent years, the demand for free form, complex and microscopic cutting has increased as a result of the need for highvalue-added fabrication for items such as high NA glass lenses, micro-grooves, diffractive aspheric lenses and other optical components. The ultra-precision machine for cutting ...

Precision displacement measurement by active laser heterodyne interferometry.

We demonstrate an active laser heterodyne interferometer which can automatically compensate environmental disturbances and is capable of precision displacement measurement. Two Zeeman He-Ne lasers were employed. Laser II was used as the light source to stabilize the interferometer by using a piezomirror in a feedback loop. The hetereodyne signal of the two lasers was used to directly calibrate ...

Development of a high precision interferometric set-up for the measurement of polarization mode dispersion

— The measurements of different parameters remained always a prime feature of the practical development of any accurate system. In connection with the optical communication, Phenomenon of PMD in single mode optical fibers takes place due to enormous polarization cross couplings throughout a specific length of the fiber and becomes a deteriorating factor for high speed fiber optic networks. We h...
