Hello,

I'm using opt3101evm (2khz) to capture an 50 mm object which travels at 10meter per second

Below is what i captured, every time sensor distance will fall to ZERO, whenever object is entering its scanning area.

Is it normal.? if so, why?

Hi Tian,

The GUI for OPT3101 (latte) has an option for outputting a CSV file. Can you please share this file showing this problem?

Best,

Alex

Hi Mike.

Aside from the phase I am also seeing the amplitude spiking to saturation during these times that phase is dropping to zero. What speed are you operating at? If you are at max 4ksps can you try a lower speed and see if you still see this?

Best,

Alex
