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 .
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.
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claim(s) 1-19 is/are rejected under 35 U.S.C. 103 as being unpatentable over Zhuo Ziyin, CN113406596B in view of Blaise Gassend, US20210199779A1.
Regarding claim 1, Zhou teaches a scanning system comprising, a scanner and a light isolator ([0012] scanning mirror and optical isolator), wherein the scanner is divided into a first sub-scanner and a second sub-scanner based on the light isolator ([Fig.1] sub scanners (11, 111, 113) divided based on light isolator (200)), wherein: the first sub-scanner is configured to reflect, to a detection area, detection light from an emitting module ([0031] scanning mirror used as a reflector for emitting light); the second sub-scanner is configured to reflect an echo signal to a receiving module, wherein the echo signal comprises reflected light obtained by reflecting the detection light by a target in the detection area ([0031] scanning mirror reflect the echo light to reach the signal receiving point to achieve reception);
Zhou does not teach, a light isolator comprises at least one of a first flange or a second flange, wherein the first flange faces a side of the first sub-scanner, and the second flange faces a side of the second sub-scanner.
Gassend teaches, a light isolator comprises at least one of a first flange or a second flange, wherein the first flange faces a side of the first sub-scanner, and the second flange faces a side of the second sub-scanner. ([0104] at least one baffle facing the side of a scanning mirror)
It would have been obvious to a person having ordinary skill in the art to modify the scanning system of Zhou to include flanges similar to that of Gassend with a reasonable expectation of success. This would have the predictable result of significantly reducing the stray light inside the scanning system allowing the LiDAR to have a greater detection accuracy.
Regarding claim 2, Zhou as modified above teaches the system of claim 1, wherein the light isolator further comprises a bottom plate, the bottom plate is disposed between the first sub-scanner and the second sub-scanner, and the bottom plate is surrounded by at least one of the first flange or the second flange. (Zhou [0049] optical isolation plate fixes to a support protrusion)

Regarding claim 5, Zhou as modified above teaches the system of claim 4, wherein at least one of a first surface of the support has an extinction function, a second surface of the second flange has an extinction function, or a second surface of the first flange has an extinction function (Zhou [0049] optical isolation plate fixes to a support protrusion); and the first surface of the support is a surface that is of the support and that faces the second flange, the second surface of the second flange is a surface that is of the second flange and that faces the support, and the second surface of the first flange is a surface that is of the first flange and that faces the support (Zhou [0049] optical isolation plate fixes to a support protrusion).
