Greetings..
I am looking into advanced safety shutter control for a new projector I am working on..
I will be employing two physical mechanical shutters, one shutter for normal show control / beam shuttering. The second shutter being an emergency shutter - this is on top of laser blanking..
I am looking at different monitoring methods, such to be able to trigger the shutter in an emergency situation such as scanner failure. By monitoring the input signal to the scanner drivers and the actuall scanners, should a fault occure where the scanners stop (yet you still have the X-Y data available), the show control / beam shutter will not close (thus you will have a laser entering the scan-block, and a static beam output..
I realise that currently, beam shuttering can be relied on by AOM/PCAOM and physical mechanical shutter, yet how are the scanners being monitored such to trigger the emergency shuttering / attenuation of the laser such not to enter the scan-block ?
Thanks
Flavio
