Abstract

Demand for a cheap and simple laser detector in industry has become high due to a growing number of laser sources. Clearly, a rugged, simple, and cheap method of detecting these laser wavelengths had to be devised. The problems inolved were to 'see' the wavelength to recognize and identify it. To do this, some form of optical device for channeling captured light into the detector was devised. This light had to be converted into a digital signal, then to a digital readout giving information on the wavelength received. In turn this information could be used to operate devices to take any appropriate action on incoming wavelengths. The electro-optical methods that were used and devised at DRA Malvern are described including an outline to the history of this project. The working solutions and results are also contained in this report.
