Abstract: This is an electronic scheme for correcting for mechanical misalignment and chromatic aberrations from laser beam to laser beam in the scan direction of a multiple beam laser scanning system for use in an electrophotographic machine. Each beam is first corrected for mechanical misalignment and thereafter for chromatic aberrations. A reference laser beam produces two pulses near the start of scan (SOS) and two pulses near the end of scan (EOS). A non-reference laser beam then produces SOS and EOS pulses from which the mechanical misalignment is calculated. A gated clock is energized by the reference pulse and a tapped delay line is used for nanosecond resolution. After accomplishing correction for mechanical misalignment, chromatic aberrations are corrected by measuring the amount of total pel displacement of the non-reference scan line relative to the reference scan line and inserting appropriate delays at selected intervals throughout the non-reference scan in order to maintain pel placement accuracy to a desired tolerance.

Abstract: A multiple laser beam scanning optical system for correcting monochromatic and polychromatic abberations comprising a doublet cylindrical lens (25) for receiving the multiple beams and directing them to a rotating polygonal mirror (26). Scanning lens means are located to receive the beams from the mirror and direct them to the image plane (32). The scanning lens (27, 29) is comprised of at least one doublet wherein both elements have approximately the same index of refraction, but different dispersion factors at a nominal wavelength.

Abstract: A method for processing a semiconductor wafer includes applying a release layer to a transparent handler (S11). An adhesive layer, that is distinct from the release layer, is applied between a semiconductor wafer and the transparent handler having the release layer applied thereon (S12). The semiconductor wafer is bonded to the transparent handler using the adhesive layer (S13). The semiconductor wafer is processed while it is bonded to the transparent handler (S14). The release layer is ablated by irradiating the release layer through the transparent handler with a laser (S16). The semiconductor wafer is removed from the transparent handler (S17).

Abstract: A HEAD MOUNTED VIRTUAL IMAGE DISPLAY UNIT (10) IS PROVIDED WHICH IS COMPACT IN SIZE AND WEIGHT, AND INCORPORATES A HIGH PERFORMANCE OPTICAL SYSTEM (100) OFFERING A CLEAR SEE-THROUGH CAPABILITY. A SLIDING LIGHT SHIELD (3200) MAY BE INCORPORATED FOR THOSE INSTANCES WHEN SEE-THROUGH CAPABILITY IS NOT DESIRED. A FOCUS ADJUSTMENT (1200, 1300) MAY BE INCORPORATED TO PERMIT THE FOCUSING OF THE IMAGE, FOR EXAMPLE, AT A DISTANCE OF APPROXIMATELY 18 INCHES TO INFINITY. AN ADJUSTABLE HEADBAND (500) MAY BE INCORPORATED THAT ADAPTS TO FIT THE USERS HEAD. A FLEXIBLE BOOM (200) STRUCTURE MAY BE INCORPORATED TO FACILITATE FINE POSITIONAL ADJUSTMENT OF THE OPTICAL ASSEMBLY.A SLIDER AND BALL JOINT MECHANISM MAY ALSO BE INCORPORATED TO FACILITATE POSITIONAL ADJUSTMENT OF THE OPTICAL ASSEMBLY. A BUILT-IN MICROPHONE (2700) MAY BE INCORPORATED TO ENABLE SPEECH INPUT BY THE USER.THE HEAD MOUNTED VIRTUAL IMAGE DISPLAY UNIT MAY BE USED COMFORTABLY IN CONJUNCTION WITH EYE OR SAFETY GLASSES, AND PROVIDES A USEFUL IMAGE TO THE USER WITHOUT BLOCKING HIS VIEW OF THE SURROUNDING ENVIRONMENT. THE UNIT IS DESIGNED TO HAVE A PLEASING APPEARANCE SO AS TO GREATLY ENHANCE USER ACCEPTABILITY.(FIG 3A)
