Repeatability
The TF-Luna's range repeat accuracy is directly related to the strength value measured and the output
frame rate (frequency). The ranging repeat accuracy is characterized by the standard deviation of ranging.
When the frame rate is 100 Hz, the standard deviation of ranging is as follows under the background of 90%
transmittance:
