Beamage-M

User Manual Revision 2.0 13

Figure 2-3 Time Delayed Spatial Slices (ROIs)

Three methods can be used to measure the M

factor. The first two methods consist of using only one Beamage-

3.0 camera and one Beamage-M2 module. The third method uses two Beamage-3.0 cameras and one Beamage-

M2 module.

3. How to Use It

3.1. “Moving Stage” Calibration Mode Mechanical Setup

The first method consists of the simplest optical setup. The Beamage-M2 module must be moved by a known

distance to calibrate the measurement. This method, although simple, has the highest uncertainty.

3.1.1. Standalone Laser

Figure 3-1 Moving stage calibration camera setup with a Standalone Laser

This section will guide you through setting up the necessary components for the M

factor measurement with a

single camera and a standalone laser. The use of an optical table or breadboard is recommended to align the

optical elements.

1- Fix the Beamage-M2 module on the optical breadboard using a stand. It is also recommended to use a

short millimetric moving stage to help you move the camera back and forth along the propagation axis.

In a subsequent section, this will help you to calibrate the device accurately.
