This was demonstrated in a project undertaken recently, and is a typical example of what of multi-user systems see in the field.
A manufacturer of medical implants uses eight (8) pulsed lasers to perform cutouts on the medical implant. The accuracy and repeatability of the energy of each pulse is directly linked to the yield of the production facility.
The manufacturer has mapped the failure mode source to irregular pulse energy. His requirement is to measure the pulse energy in real time and to store the data for analysis. Another request was to make a quick and neat installation with no additional cables to be laid out in the production floor, due to clean room considerations.
The production floor is controlled from a central location through a server connected to the lasers.
Each laser fires its pulses through a beam splitter, which splits off a fraction of the pulse energy into a pyroelectric sensor, resulting in an "online" measurement system. The pyroelectric sensor is connected to an Ophir Quasar wireless interface which transmits the measurement data in real time to a server, storing the data into a SQL database. The server collects data from all eight lasers through eight Quasar interfaces, one for each laser.
