Claims
- 1. A method of aligning a lens train assembly within a head-up display unit, said lens train assembly having a plurality of lenses, comprising the steps of:
connecting said lens train assembly to a cathode ray tube, said cathode ray tube having a display screen; projecting a controlled electron beam through said lens train assembly whereby projecting a display upon said display screen; mapping the field of display pixels within said display screen using set mapping coordinates whereby creating alignment correction information; interpolating said alignment correction information between said display pixels whereby obtaining alignment mapping information for each individual display pixel location; storing said alignment correction information in a storing means; installing said head-up-display unit; recalling said alignment correction information from said storing means; and aligning said head-up display unit based upon said alignment correction information with an alignment means.
- 2. A method as claimed in claim 1 wherein said field of display pixels consists of each individual display pixel.
- 3. A method as claimed in claim 1 wherein said field of display pixels consists of singular regions of approximately 4×4 display pixels each defining a square whereby the total set of regions is approximately 1024×1024.
- 4. A method as claimed in claim 1 wherein said mapping coordinates consists of a sample of approximately 25 to 100 field of display pixels.
- 5. A method as claimed in claim 1 wherein said storing means consists of nonvolatile memory.
- 6. A method as claimed in claim 5 wherein said non-volatile memory is fixedly attached to said lens train assembly.
- 7. A method as claimed in claim 1 wherein said storing means consists of a central storage location.
- 8. A method as claimed in claim 1 where said alignment means consists of adjusting the cathode ray tube deflection coil current.
