Laser time-of-flight velocimetry: proposals for minaturisation

摘要

The need for miniaturised sensors in a production environment is rising duet o the pressure for on-line quality control. Efficient monitoring of the production process reduces raw material waste, increases productivity and lowers operating costs. currently, mechanical contact sensors and magneto/electro non-contact sensors are employed. Optoelectronic sensors can provide an attractive alternative, as the optical signa probe is non-contacting, is immune to electric and magnetic fields, and can deliver a more accurate measurement. However, in order for optical sensors to be a viable alterantive, accuracy and cost effectiveness is an issue, expecially as compared to the savings obtained as a result of the increased accuracy.
