Abstract
Abstract A slewable projection system of the type having a relatively high-resolution area-of-interest (AOI) scenic portion inset into and blended with a relatively low-resolution field-of-view (FOV) scenic portion of greater areal extent than the high-resolution portion, includes: at least one optical element for providing the low-resolution background image portion; at least one other optical element for providing the high-resolution AOI image portion; an optical combiner receiving the low-resolution and high-resolution image portions; optics for projecting the combined image onto a viewing area; and at least one fiber-optic cable having a multiplicity of fibers for interconnecting the combining element and at least one of the two image optics portions and the projecting optics. A fiber-optic element can mechanically decouple the combining and projecting elements, so that high projection slew rates and accelerations can be realized, while also eliminating hard optics associated with image de-rotation and/or focusing. Another fiber-optic element can provide moveable area-of-interest blending at any selected location over the entire area of the background scene, without movement of a projector or other high-pass subassembly. Use of yet another fiber-optic element can facilitate dynamic image merging.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
85 words
A slewable projection system of the type having a relatively high-resolution area-of-interest (AOI) scenic portion inset into and blended with a relatively low-resolution field-of-view scenic portion, comprising: at least one means for providing a low-resolution image portion; at least one means for providing the high-resolution image portion; means for combining the low-resolution and high-resolution image portions; means for projecting the combined image onto a viewing area; and at least one fiber-optic means for passing combined image information from the combining means to the projecting means.
Claim 2
Dependent Claim
85 words
A slewable projection system of the type having a relatively high-resolution area-of-interest (AOI) scenic portion inset into and blended with a relatively low-resolution field-of-view scenic portion, comprising: at least one means for providing a low-resolution image portion; at least one means for providing the high-resolution image portion; means for combining the low-resolution and high-resolution image portions; means for projecting the combined image onto a viewing area; and at least one fiber-optic means for passing combined image information from the combining means to the projecting means.
Claim 3
Dependent Claim
21 words
The system of claim 1, wherein one of the fiber-optic means is a cable comprised of a multiplicity of optical fibers.
Claim 4
Dependent Claim
76 words
The system of claim 2, wherein each fiber has a first end arranged substantially together with the first ends of all other fibers of the cable into a cable proximal end receiving the combined image optical information, and each fiber has a second end arranged substantially together with the second ends of all other fibers of the cable into a distal end transmitting substantially the same combined image optical information as received by the proximal end.
Claim 5
Dependent Claim
49 words
The system of claim 3, wherein at least one of the proximal and distal ends is adapted for spatial movement to re-orient the combined image optical information transmitted from the cable distal end, with respect to the orientation of the same information as received at the cable proximal end.
Claim 6
Dependent Claim
31 words
The system of claim 4, wherein the at least one cable end is moved to rotate the orientation of the output information with respect to the orientation of the input information.
Claim 7
Dependent Claim
30 words
The system of claim 5, wherein another end of the cable is moved to translate the position of the output information with respect to that means receiving the output information.
Claim 8
Dependent Claim
31 words
The system of claim 5, wherein the same end of the cable is moved to translate the position of the output information with respect to that means receiving the output information.
Claim 9
Dependent Claim
90 words
The system of claim 1, further comprising: first means for removing a selected portion of the low-resolution image; second means for transmitting only a substantially complementary inset portion of the high-resolution image to match the removed low-resolution image portion; and the fiber-optic means includes a cable formed of a multiplicity of optical fibers each having a first end arranged in a cable proximal end receiving high-resolution information and a second end arranged in a cable distal end transmitting substantially the received information to the image-transmitting portion of said second means.
Claim 10
Dependent Claim
30 words
The system of claim 8, further comprising means for causing the location of the removed portion of the low-resolution image to track the location of the inset high-resolution image portion.
Claim 11
Dependent Claim
139 words
A slewable projection system of the type having a relatively high-resolution area-of-interest (AOI) scenic portion inset into and blended with a relatively low-resolution field-of-view scenic portion, comprising: means for providing the low-resolution image portion; first means for removing a select portion of the low-resolution image to provide a modified low-resolution image portion; means for providing the high-resolution image portion; second means for providing a modified high-resolution image portion by transmitting only a substantially complementary inset portion of the high-resolution image matching the removed low-resolution image portion; means for combining the modified low-resolution and modified high-resolution image portions; means for projecting the combined image onto a viewing area; and fiber-optics means having a proximal end receiving the high-resolution information from said providing means and a distal end transmitting substantially the received information to the image-transmitting portion of said second means.
Claim 12
Dependent Claim
139 words
A slewable projection system of the type having a relatively high-resolution area-of-interest (AOI) scenic portion inset into and blended with a relatively low-resolution field-of-view scenic portion, comprising: means for providing the low-resolution image portion; first means for removing a select portion of the low-resolution image to provide a modified low-resolution image portion; means for providing the high-resolution image portion; second means for providing a modified high-resolution image portion by transmitting only a substantially complementary inset portion of the high-resolution image matching the removed low-resolution image portion; means for combining the modified low-resolution and modified high-resolution image portions; means for projecting the combined image onto a viewing area; and fiber-optics means having a proximal end receiving the high-resolution information from said providing means and a distal end transmitting substantially the received information to the image-transmitting portion of said second means.
Claim 13
Dependent Claim
30 words
The system of claim 10, further comprising means for causing the location of the removed portion of the low-resolution image to track the location of the inset high-resolution image portion.
