Term
Description
TOF sensor
A sensor that measures the distance from a sensor to an object using the TOF method.
TOF is an abbreviation for Time of Flight. The distance is measured by emitting light and
measuring the phase difference between the emitted and reflected light.
Distance precision
Difference between the average measured value and the actual distance
Repeatability
The extent to which the measured values vary
Operation mode
- Normal mode: The HDR function is enabled and the distance is calculated based on two
measurement results.
- High-speed mode: The HDR function is disabled and the distance is calculated based on
one measurement result.
Note: HDR function: Function to make multiple measurements by changing the shutter
speed.
Start-up period
Time from powering up the B5L to the point where communication becomes available
Warm-up period
Time from powering up the B5L to the point where its performance becomes stable
Distance data
The three-dimensional distance from the coordinate origin of B5L to the object.
Cartesian coordinate system
A coordinate system defined by specifying mutually orthogonal coordinate axes
Rotated Cartesian coordinate
system
Cartesian coordinate system rotated around Xo, Yo, and Zo axes by the specified angle
Polar coordinate system
A coordinate system that represents the position of a point in a solid using its distance r
and angle
θ
as well as angle
φ
from the origin
Amplitude data
Photo sensitivity of each pixel when the LED is emitted
