Abstract
The present invention relates generally to various arrangements of optical and electronic components to form a high-resolution helmet mounted display (HMD) or other compact display device. In particular, the current invention is designed in such a way as to allow it to operate utilizing several different kinds of image generation device and to incorporate many different features including the option of “eye tracking”.

A compact display device that is capable of utilizing either reflective or transmissive display technologies for the generation of images for a helmet mounted display device (HMD) or other compact display device.
A compact display device that is capable of utilizing a combination of reflective and transmissive display technologies for the generation of images for a helmet mounted display device (HMD) or other compact display device.
An optical assembly as shown in FIGS. 1,2 which consists of mirror M1, non-polarized beamsplitter BS1, polarized beamsplitter BS3, eyepiece E1, light source LS3, reflective display device RD1, collimating lens CL1 and optional components consisting of infrared filter F1, camera ETC1, and infrared light sources LS1.
An optical assembly as shown in FIGS. 1,2 which consists of mirror M2, non-polarized beamsplitter BS2, polarized beamsplitter BS4, eyepiece E2, light source LS2, reflective display device RD2, collimating lens CL2 and optional components consisting of infrared filter F2, camera ETC2, and infrared light sources LS2.
An eye tracking module which utilizes the optical configuration as described in claims, 5-7,13-15,35 and shown in FIG. 1 which can determine both the position and orientation of an individual eye of the user and from this information can calculate both the mis-alignment between the eyepiece optics E1,E2 and the viewer's eye and the “line-of-sight” for that particular eye
