We reported earlier that holographic stereograms are approaching a level of realism typical of other, more mature, graphical media (Kosnik, Previc, Polhamus, 2001). As image quality and realism improve, holograms may offer certain advantages over mor

With the advent of such systems as the airborne laser and advanced tactical laser, high-energy lasers that use 1315-nm wavelengths in the near-infrared band will soon present a new laser safety challenge to armed forces and civilian populations. Expe

The growth of commercially available, simultaneous multi-wavelength laser systems has increased the likelihood of possible ocular hazard. For example, many systems utilize frequency multiplying methods to produce combinations of visible, near-infrare

To properly assess the retinal hazards from several lasers using multiple wavelengths, the retinal effects of 10-second laser irradiation from 532 and 860 nm were determined in non-human primates for several different power combinations of these wave

The U.S. Dept. of Defense (DOD) is currently developing and testing a number of High Energy Laser (HEL) weapons systems. DOD range safety officers now face the challenge of designing safe methods of testing HEL's on DOD ranges. In particular, safety

With the advent of future weapons systems that employ high energy lasers, the 1315 nm wavelength will present a new laser safety hazard to the armed forces. Experiments in non-human primates using this wavelength have demonstrated a range of ocular i

Though allowable (safe) energy doses of pulsed laser radiation have been determined in the central retina, the sensitivity of the peripheral retina to damage must also be assessed. We used results from ray-tracing in an eye model to estimate laser sp

The realism of reflection holographic stereograms was evaluated to determine how acceptable they are to a non-technical audience. The stereograms were rated for realism by comparing them to photographic images and real objects. Although the ratings w
