So, has there been any progress on getting this sensor to market?
I'm trying to get a laser machine built, but, this is one of the toughest issues I'm facing. I have a MESA 7i76EU that I have been trying to interface a BCL-AMP output to. I have the BCL-AMP connected to a Raytools BT210S002A cutting head sitting on the bench with a chunk of steel in front of it and grounded to the case of the Raytools cutting head. Between the BCL-AMP and the 7i76EU, I have a TI SN74HCS74DR dual Schmidt Trigger Flip Flop that I'm using to divide the BCL-AMP output frequency by 2 and "clean it up" at the same time. However, it's just not very stable. The velocity measured by the 7i76EU jumps around about 600-700 hz. The velocity range only seems to be around 6500 hz from 0-10mm (3/8") sensing distance, so, my positional sensitivity sucks at around 0.1 inches. Just for giggles, I ran the signal through 4 Flip Flops to see if the 'jumping around' would decrease. It didn't. Which leads me to believe the instability is introduced somewhere in my circuitry or wiring. I even tried connecting Q and Q not outputs into the MESA card as differential signals and twisted the wires. No help.
Anyhow, This CV2 height sensing device sounds very promising.
