PLEASE NOTE THIS A SOURCES SOUGHT NOTICE ONLY
Title: 3D Photometric Stereo Microscope
BACKGROUND
NIST performs research and measurements in the field of surface topography and the forensic analysis of toolmarks. A photometric-stereo 3D scanning microscope system is needed that can acquire 3D scans of surfaces. Samples to be measured will include those that have steep local slope angles and be made of transparent or translucent materials, such as glass and various polymers. The ability to accurately measure these surfaces is critical to the research being performed. NIST requires an imaging microscope that can produce three-dimensional (3D) surface topography scans of samples under test. The microscope method of operation shall be of a photometric-stereo design.
The 3D photometric stereo microscope will be used in three areas of research:
Identifying toolmarks on the surfaces of 3D printed parts as part of a research project funded by the National Institute of Justice (NIJ). The goal of this project is to test the ability to identify the 3D printer that a specific part was 3D printed from by comparing surface features and toolmarks that are produced on the printed part by the 3D printer. These include toolmarks transferred to the printed part from the 3D printer-s build plate and heated nozzle. Samples to be scanned include the 3D printed parts which may be produced from various polymers (PLA, ABS, PETG) as well as the components of the 3D printer (build plates, nozzles). Some materials are translucent in nature and may have high slope angles due to the 3D printing process. The ability to scan and acquire accurate 3D surface topography images of these samples is critical in meeting the deliverables of the project.
Research related to general surface texture analysis of samples. This includes samples that may be produced from transparent materials, such as glass, and those with surface features that have high local slope angles (...
