FAST RESPONSING LASER SENSOR AND ARDUINO BOARD

by sreeji561 on Fri Mar 27, 2020 5:21 am

I would like to measure the displacement of a surface.
-Sampling rate required- 9,000 Samples per second
-Range of displacement 0 to 1m
-Resolution required <1mm

Kindly help me to choose proper board and sensor.

Currently I have used UNO with VL53L0x sensor. This combination works maximum 21 samples per second. Is there any way to get this sensor more fast. Or I should go for new sensor and new board.

We do not carry any rangefinding sensors that operate at the speeds you require.

Can we have sensor with 1000Hz response time with remaining specifications are same.

We do not have any ranging sensors that approach that sample rate.
The theoretical max sample rate for the VL53L0X is about 30 Hz.
The TFMini is a bit faster at about 100 Hz.

For operation at those speeds, you will probably need to look to industrial grade sensors. Here is one possibility:
