Why an optically‐based hydrophone works better

V.J. Hughes, J.G. Boulton, J.M. Coles, T.R. Empson, N.J. Kerry

A new type of hydrophone using optical technologies has distinct advantages over traditional types.

Attention focuses on optical fibre biosensors

P. Roef

Optical fibre sensors are finding wide applications in biotechnology and medicine, as a European specialist explains.

Artificial intelligence: sensors need it

Where is practicable AI heading? Probably into complex military command and control systems, as Stephen McClelland explains.

A close inspection of vision systems

Clive Loughlin looks at some of the systems available to industry, and analyses their strengths and weaknesses.

A new angle on 3‐D coordinate determination

R. Gottwald, W. Berner

Development of the electronic precision theodolite has led to the automation of 3‐D coordinate determination.

Positional and rotational control using flexible drives

E.J. Atherton

Awkward positional problems in robotics could be solved by flexible drives, an inventor claims.

Inspex measures up to expectations

Inspex, the UK quality assurance exhibition, was this year the most comprehensive of the biennial series. Jack Hollingum was there.

Vision systems or vision sensors?

Bill Vogeley

Many industrial applications could benefit from line imaging‐based edge sensors rather than full‐scale vision systems, a leading specialist argues.
