The steps of the use of the laser technique is explained below:
- A laser beam is emitted from the diode in the unit and spread into a laser plane (1).
- The laser plane, appearing as a line on the sphere (2), is reflected and collected by dual CCD arrays (1).
- The resulting 2D profile is digitized and as the unit travels along the x-axis of the object, multiple profiles are collected yielding a 3D coordinate point cloud of the surface (3).
<h3>What is a Laser Technique?</h3>
This refers to the type of surgery that makes use of special light beams in order to cut open the human body in a surgical procedure.
Hence, we can see that the laser technique is considered safer than conventional surgical methods.
Laser techniques include:
- laser vaporization,
- laser resection-enucleation,
- coagulation.

Answer:
Q = 47.06 degrees
Explanation:
Given:
- The transmitted intensity I = 0.464 I_o
- Incident Intensity I = I_o
Find:
What angle should the principle axis make with respect to the incident polarization
Solution:
- The relation of transmitted Intensity I to to the incident intensity I_o on a plane paper with its principle axis is given by:
I = I_o * cos^2 (Q)
- Where Q is the angle between the Incident polarized Light and its angle with the principle axis. Hence, Using the relation given above:
Q = cos ^-1 (sqrt (I / I_o))
- Plug the values in:
Q = cos^-1 ( sqrt (0.464))
Q = cos^-1 (0.6811754546)
Q = 47.06 degrees
It means the speed of the object is increasing
and
there is a positive acceleration in the direction of the velocity
hence
there is a force acting on the object, in the direction of the velocity
