Quick-look eye-safety assessment for the short range lidar
This is a quick-look eye-safety assessment for the Short Range (SR) lidar, a system under development for standoff biological aerosol detection in the outdoor environment. The ground-vehicle-mounted SR lidar system will scan a sector of the nearby atmosphere with a repetitively pulsed, multiple-wavelength, UV/IR laser beam. This laser is not intrinsically eye-safe, and hence the SR lidar system requires a protection system to minimize the risk of eye exposures above the ANSI-standard maximum permissible exposure within a nominal hazard zone. The nominal ocular hazard distance for the UV/IR laser itself was calculated to be 6 km. The protection system, which will include a scan-stop detector and a laser beam path interrogator, currently is conceptual only. Until the complete protection system is designed, evaluated, and tested, and a more detailed safety assessment has been performed, the eye-safety issue for the SR lidar system cannot be resolved.
