What does laser scanning at a crime scene entail?

Answer :

Final answer:

Laser scanning at a crime scene involves using lasers to create high-resolution images at different depths, which can be combined to form a three-dimensional representation. This technique is particularly useful for studying thick specimens like biofilms in forensic investigations.

Explanation:

Laser scanning at a crime scene entails using lasers to scan multiple z-planes in order to create two-dimensional, high-resolution images at various depths. These images can then be compiled into a three-dimensional representation using a computer. This technique is useful for examining thick specimens, such as biofilms, in forensic investigations.

Scanning systems like the Artec Ray speed up the process of crime scene investigation by creating an accurate three-dimensional representation of the scene of a crime. Police and insurance companies can use the 3D world to take measurements, inspect evidence, and analyze blood splatter or bullet trajectory.

Specialized software drives the laser probe above the surface of the object. The laser probe projects a line of laser light onto the surface while 2 sensor cameras continuously record the changing distance and shape of the laser line in three dimensions (XYZ) as it sweeps along the object.
