An examiner's amendment to the record appears below. Should the changes

and/or additions be unacceptable to applicant, an amendment may be filed as provided

by 37 CFR 1.312. To ensure consideration of such an amendment, it MUST be

submitted no later than the payment of the issue fee.

The title of the invention as been changed to: -Compact image projector having

a mirror for reflecting received beam from a polarization beam splitter back to the

polarization beam splitter-.

The following is an examiner's statement of reasons for allowance: The prior art

or record fails to teach a device and it method, among other features, comprising a

mirror adapted for reflecting a received beam from a polarization beam splitter back to

the polarization beam splitter in which a first quarter wave plate imparts on the reflected

beam a first polarization that causes the polarization beam splitter to direct the reflected

beam to a spatial light modulator, wherein the spatial light modulator is adapted to

spatially modulate the received beam from the polarization beam splitter and direct a

resulting spatially modulated beam back to the polarization beam splitter, and a second

quarter wave plate imparts on the spatially modulated beam a second polarization that

causes the polarization beam splitter to direct the spatially modulated beam to an output

port to form an output beam.

Any comments considered necessary by applicant must be submitted no later

than the payment of the issue fee and, to avoid processing delays, should preferably

accompany the issue fee. Such submissions should be clearly labeled "Comments on

Statement of Reasons for Allowance."

The prior art made of record and not relied upon is considered pertinent to

applicant's disclosure.
