Precision Simulations, Inc. has been at the forefront of Laser Scanning with these pioneering milestones.
- First Forensic Animation based upon Laser Scanning data - Santa Barbara 1999
- First Animation admitted into trial in US based upon Laser Scanning data (Leica HDS2400) - Honolulu 2000
- Pioneered Laser-Assisted Photogrammetry (LAP) - 2003
- Pioneered use of LAP to accurately recreate & position physical evidence only captured in photographs (Leica HDS3000) - San Francisco 2004
- PSI has performed and directed more than 40 3D Laser Scanning projects and over 500 3D Forensic Animations.
- PSI’s Laser Scanning data & animations are routinely admitted in trial.
What is it?

A 3-D laser scanner is an advanced type of survey/measurement instrument that is used to remotely measure surface geometry of sites and structures with extraordinary completeness, accuracy and speed.
Unlike traditional surveying tools that are used to record certain, selected points within a scene, a 3-D laser scanner automatically "blankets" the scene with hundreds of thousands or even millions of closely spaced point measurements. By repeating this process across the scene rapidly - over 1000 times/sec - the laser quickly constructs a precise, 3-dimensional model, comprised of millions of measurements, for later use in reconstruction analysis and illustration.

When we decided to get PSI involved in producing an annimation we had no idea they'd have the impact they would. We were amazed.
Larry Spelling, esq. Wietrab & Wietrab
Results: The defense attorney, assisted by the expert's comprehensive reconstruction, and PSI's computer generated simulation, was able to determine that the physical evidence corroborated the peace officers' version of the incident and conclusively established that the officers' use of deadly force was reasonable.
