3D laser scanners are becoming more popular and more available to the general public. They can be purchased through companies such as Keyence, NextEngine, or Trimble. They may also be found on sites such as eBay from time to time.
A laser scanner emits laser beams in multiple directions and measures the time it takes for the beams to reflect back to the scanner. By capturing the precise distances to objects in the environment, the scanner creates a point cloud, which is then used to generate a 3D model of the crime scene. This model provides detailed spatial information that can be used for investigation and analysis.
The former ie "I bought a scanner off you" or "I bought a scanner from you"
