In laser safety, two well-established concepts are the Maximum Permissible Exposure and the Nominal Ocular Hazard Distance. While the nominal ocular hazard zone (NOHD) at full power is 130 feet, the device includes a safe, low-power laser that measures the distance to a person or reflective object, and lowers the light level so it is safe at the detected distance. In various embodiments, laser dazzling devices according to the present invention include non-polar and/or semi-polar green laser diodes.

PDF Lasers Health Physics - JHSPH While the nominal ocular hazard zone (NOHD) at full power is 130 feet, the device includes a safe, low-power laser that measures the distance to a person or reflective object, and lowers the light level so it is safe at the detected distance. One method is to use an eye-safe rangefinder to determine the laser-to-eye distance, and then set the laser power so it dazzles but does not damage. intermediate-powered lasers and may be hazardous under direct and specular reflection viewing and may be hazardous with diffuse reflection if the eye is appropriately focused and stable. Meyers. Military dazzlers do not have such a feature, relying instead on training soldiers not to aim the laser . The laser beam can thus be considered as dangerous if the operator is closer from the source than the N.O.H.D. As a result, the dazzler may be specified with a Nominal Ocular Hazard Distance (NOHD) which is the distance under . Would you like email updates of new search results? AU - Sliney, David H. PY - 2013. Beyond the Nominal Ocular Hazard Distance, the chance of injury is vanishingly small according to safety experts. bar code scanners used in checkout counters are an example. would not block vision but would be brighter than city and airport lights seen outside the cockpit window. The hazard distance corresponding to the MPE is called NOHD. Using the GBD-IIIC alone has the potential to cause eye injury when used within the Nominal Ocular Hazard Distance (NOHD) of 62.9 meters established by the Navy Laser Safety Review Board (NLSRB) on 8 May 2009. Another important definition for laser safety calculations is the Nominal Hazard Zone (NHZ). The concept of Nominal Ocular Dazzle Distance tells us how far the laser beam will go before we can see the 5-wide runway. This paper presents a method of estimation of the nominal ocular hazard distance (NOHD) and the nominal . Along laser beam can thus be considered as dangerous if the operator is from Below which a given target can be detected target can be sent out to 4 at. 4 Avoiding direct eye exposure to a laser's beam closer than the NOHD through the wearing of eye protection is recommended, as the beam .
