DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Delapp (WO 2022/066461). Reference to Delapp (WO 2022/066461) will be made to Delapp et al. (U.S. 2023/0314810), which is an equivalent English translation of Delapp (WO 2022/066461).
Regarding claim 1, Delapp discloses a volume holographic optical element (32, Fig. 9; page 5, para [0051]) to avoid ghost noise, wherein:
the volume holographic optical element (32, Fig. 9) includes a plurality of volume gratings (72 and 74, Fig. 9; page 5, para [0051, 0053]), which correspond to different incident angle lights, respectively (such as 72 corresponding to incident light of 38 towards the +Y direction, Figs. 4 and 9; page 5, para [0052]; and such as 74 corresponding to incident light of 38 towards the -Y direction, Figs. 4 and 9; page 6, para [0054]), and have vectors (kg1 and kg2, Fig. 9; page 5, para [0052]; page 6, para [0054]) designed with the same component horizontal to an incident interface (kg1 and kg2 each have a same component horizontal to a planar light incident surface of 28 on the X-Y plane, Figs. 4 and 9, page 5, para [0052]; page 6, para [0054]) and possess identical grating periods horizontal to the incident surface (72 and 74 each possess identical grating periods p1 and p2, respectively, that are horizontal to the planar light incident surface of 28 on the X-Y plane, Figs. 4 and 9; page 5, para [0052]; page 6, para [0054]).
