FSC239Y5 Lecture Notes - Lecture 1: Lidar, Structured Light, Stimulated Emission
Document Summary
Use of 3d technologies that assist with the documentation, analysis, reconstruction and visualization of evidence. A reconstruction is based on available physical evidence and can be used for analysis or substantive purposes. A recreation is mostly a creative" work (although it may be based in part on physical data), it may rely on witness testimony or other non-physical sources of data. Bloodstain pattern analysis (rcmp test laser tech) Forensic anthropology (pubic symphysis to determine sex of the individual) Image stacking to take pictures to show depth analysis. Fringe patterns (black and white stripes shone on objects) Structured dots (emits structured series of dots which are laser source) Taking photos at different angles for photogrammetry. Slam devices (simultaneous localization and mapping) laser based devices. Laser (light ampli cation through stimulated emission of radiation) Distance total time=t speed of light = c d=c x t x 1/2.
