Improved Precision Measurement of the Casimir Force
We report an improved precision measurement of the Casimir force. The force is measured between a large Al coated sphere and flat plate using an Atomic Force Microscope. The primary experimental improvements include the use of smoother metal coatings, reduced noise, lower systematic errors and independent measurement of surface separations. Also the complete dielectric spectrum of the metal is ...
متن کاملStudent-Friendly Precision Pendulum
Student-Friendly Precision Pendulum Germany (latitude 52 N → 981,274) in the early part of this century. With the information provided in this article, students should be able to easily measure the gravitational field strength to a few parts in 10,000, a degree of precision one to two orders of magnitude better than can be achieved with the usual simple pendulum under comparable conditions. The...
متن کاملDeveloping a Method for Increasing Accuracy and Precision in Measurement System Analysis: A Fuzzy Approach
Measurement systems analysis (MSA) has been applied in different aspect of industrial assessments to evaluate various types of quantitative and qualitative measures. Qualification of a measurement system depends on two important features: accuracy and precision. Since the capability of each quality system is severely related to the capability of its measurement system, the weakness of the two...
متن کاملImage Processing for Precision Atomic Force Microscopy
Atomic Force Microsopy (AFM) is an increasingly popular means of obtaining accurate metrological data of surface topography. The AFM measures surface topography by recording the vertical motion of a probe as it traces the profiled surface in a raster fashion. However, the metrological accuracy of AFM images is limited by image convolution between the probe tip and the sample surface. As a resul...
متن کاملWeak Force Measurement in Bistable Optomechanical System
One of the main milestones in the study of opto-mechanical system is to increase the sensitivity of weak forces measurement up to the standard quantum limit. We have studied the detection of weak force under a bistable condition in red detuned regime. In this case, dynamics of the system behaves asymptotically similar to stationary state and applying external force affects phase and fluctuation...
