One of the tasks specified for the vision group of the RIPR project is the implementation of a run time inspection cell which is able to identify a small object, and to subsequently inspect it using a single camera, referred to as the inspection camera, attached to a robot arm. As a definite example, we may want to determine whether a hole has been machined on a particular face of the object wi...

In recent years there has been an explosive development of interest in the measurement of forces at the microscopic level, such as within living cells [1, 2, 3], as well as the properties of fluids and suspensions on this scale [4], using optically trapped particles as probes. The next step would be to measure torques and associated rotational motion [5]. This would allow measurement on very sm...

This paper celebrates the progress in optical frequency standards and measurement, won by the 40 years of dedicated work of world-wide teams working in frequency standards and frequency measurement. Amazingly, after this time interval, the field is now simply exploding with new measurements and major advances of convenience and precision, with the best fractional frequency stability and potenti...

In this paper some advanced methods of measurement in the field of optical fibre measurement techniques are briefly described. They are used in measuring optical characteristics, geometrical characteristics and optical transmission characteristics of optical fibres. The standard methods recommended by CCl'lT are discussed as the main parts. MIRAMARE TRIESTE November 1990 To be submitted for pub...

For a fiber optical surface plasmon resonance (SPR) sensor a short part of its cladding should be removed to coat a thin layer of a metal. Usually this is problematic when an optical fiber with small core diameter is used. In this paper, a new method using µliter droplet of the HF acid for short fiber optical taper fabrication is reported. Using this method in a multi-mode optical fiber w...
