Abstract
An eye-safe Obstacle Warning System (OWS) based on a Laser-scanning Technology for helicopters was analysed during flight campaigns and by static measurements. This system of detection is composed of two parts; the Laser sensor and the Man Machine Interface (MMI), which are both described separately. Laser transmitter wavelength is 1.54 m for eye-safety. The Man Machine Interface, with stereoscopic information presented in a Helmet Mounted Display (HMD), is developed by Eurocopter Deutschland (ECD). The two and three dimensional helmet mounted displays of a Kaiser LCD-helmet and Sony LCD-glasses, shown during several presentations of the OWS subject, have impressed all viewers with their quality and realism. The landscape is clearly visible and recognisable by every viewer. The stereoscopic representation is very good due to the real 3D information contained in the sensor measurement, and this allows more than 20 stereoscopic plans with a 640 &#61620 480 HMD to be seen.
