This page contains technical description of PhoXi 3D Scanners. For scanning guide, see Scanning best practices.

Projection unit
Light source	Visible red light (laser)
Wavelength	638nm
Laser class	3R (IEC / EN 60825-1, 2014)
Peak / CW Power	314uW
Pulse Energy	382nJ
Pulse Length	960us
Projection angle horizontal	47.5° ±1°
Projection angle vertical	36.0° ±2°

For model/size specific parameters see our product showcase.

Depth Map resolution: Maximum number of measured points (the resolution of camera sensor)

Point size: The distance between two measured points on the plane perpendicular to the camera in the focus distance from the camera.; Relation of point size to scanning distance

Absolute accuracy: The accuracy of point measurement as the result of device calibration (can be understood as the space deformation). It is the standard deviation of the measurement error in the whole measuring range of the device.

Z noise: The standard deviation of the noise (measured on a diffuse surface with 80 percent albedo). The noise level describes the quality of the sensor to capture local surface details. The noise distribution of our sensor is similar to Gaussian distribution. Can be understood as temporal noise.

FPS: Maximum number of triggered frames per second, in fastest acquisition mode

Data acquisition time - worst case: Longest expected acquisition time (bad lighting conditions, dark shiny objects)

3D points throughput: Number of 3D points that can be reconstructed in a second in sequential scans

Contains 3D Scanner body and its scanning volume as a solid object.
