Surface Temperature Mapping System Measures Laser-Heated Targets
- Created: Wednesday, 01 May 2013
Bodkin Design & Engineering, LLC (BD&E) has been awarded a $125,000 SBIR contract by NASA to develop a surface temperature mapping system for re-entry vehicle heat shields. The hyperspectral-imaging technology will provide temperature accuracy during ground tests.BD&E had already developed a Precision Surface Temperature Mapping System (PSTMS) to perform standoff measurements of laser-heated targets. Under this contract, the system will be adapted to satisfy the needs of NASA’s ground test facilities.
The sensor is capable of standoff measurement at ranges up to 100 meters, spanning temperatures from 300K to 2,000K, with high spatial, thermal, and temporal resolution. The system provides a unique dynamic analysis capability, generating up to 100 maps per second. The mapping technology’s built-in hyperspectral measurement capability also allows for calculation of surface temperature and emissivity during melting.
