Final Phase One Evaluation of the Microvision, Inc. Aircrew Integrated Helmet System (AIHS) HGU-56P Scanning Laser Display

“…Discussion: The contrast was rather uniform but proved to be somewhat less than measured previously by Rash, et al (1999). They measured an average lateral contrast of 17.8 and a vertical contrast of 16.7.…”

“…Results: Figure 4 shows the exit pupil captured from the left side compared to the exit pupil captured from the same side during the previous testing (Rash et al, 1999). The current exit pupil is more uniform than the previous sample.…”

“…Comanche requirements specify an exit pupil of 15 mm, and the new exit pupil appears to meet this requirement. The new measure refers to the most recently measured exit pupil and the old measure refers to the exit pupil measured previously (Rash, et al, 1999). The data presented here were measured on the photographs shown in Figure 4.…”

“…New measurements for the right side were not taken. Those measurements shown for the right side were taken previously (Rash et al, 1999). …”

Evaluation of Spatial Resolution in the Phase II Microvision, Inc. Aircrew Integrated Helmet System HGU-56/P Scanning Laser Display

“…Helmet-mounted display (HMD), scanning laser display, spatial resolution, modulation transfer function (MTF), contrast, (Rash et al, 1999) and 2001-06 (Harding et al, 2001) provided evaluations of earlier versions of the Microvision, Inc., HMD. This report constitutes the findings of an evaluation of the Phase II HMD, which incorporates design improvements into the earlier versions.…”
