Create a NEW landscape 3:2 Chinese educational infographic for a detailed AOM double-pass blog. Reference image is STYLE REFERENCE ONLY: adopt its attractive glass optics, clear laser rays, compact illustrated explanations, crisp navy Chinese typography, colored section bands, white background. Do NOT copy its three-column subject or its fringe diagnostics. Make one focused beautiful illustrated optical bench diagram titled exactly \"AOM 双程光路\". Premium textbook illustration: translucent pale blue PBS cube with diagonal internal interface, blue crystal AOM with subtle acoustic grating, thin purple quarter-wave plate, curved glass positive lens, silver flat end mirror, small elegant optical mounts and faint shadows. Use orthographic side-view so rays are unambiguous, not arbitrary 3D connections.\nGEOMETRY: left-to-right laser input → PBS → AOM on horizontal zero-order axis → QWP → positive lens → flat end mirror. The FIRST ORDER leaves the AOM angled slightly UP, crosses QWP and upper lens area, and becomes HORIZONTAL between lens and mirror. Lens optical center stays on horizontal ZERO-ORDER axis. End mirror is VERTICAL, normal to the first-order post-lens ray. Grey dotted zero-order beam continues horizontally through lens center and ends at a BLACK BEAM STOP before the mirror. Orange dashed RETURN retraces first-order path from mirror through lens and QWP back to AOM, then after SECOND diffraction returns horizontally left along original input axis to PBS, where it turns downward into output. Offset outgoing/return rays slightly ONLY for legibility, make all direction arrowheads correct (outbound right, return left, output down). No additional optics or extra beams. Draw a small RF driver below AOM connected to the crystal.\nLabels in Chinese, short and widely spaced: \"输入光 ν₀\", \"PBS\", \"AOM\", \"QWP\", \"透镜\", \"反射镜\", \"零级光 → 光束挡\", \"RF 驱动\", \"输出 ν₀ + 2fRF\". Blue solid outbound, orange dashed return. Above return arm label \"第一程：+fRF\"; on lower side after second diffraction label \"第二程：+fRF\". Fine dimension arrows beneath AOM-to-lens and lens-to-mirror labeled \"≈ fL\" each. Top small subtitle \"两次衍射 · 频移叠加 · 指向补偿\". Bottom two refined short note cards, exact text: \"猫眼：透镜 + 反射镜\" and \"QWP 往返使线偏振转过 90°\". Small footnote: \"示意图不按比例；需确认 AOM 的偏振兼容性\". Avoid paragraphs, avoid glare over text, avoid decorative clutter, correct coherent optical geometry above all. Large usable diagram filling canvas with generous labeling room, publication quality Chinese text.","layout_corrected":"Edit this AOM infographic with minimal precise corrections. Keep ALL composition, beautiful glass optics style, Chinese text, laser source, PBS, AOM, QWP, lens, mirror and cards unchanged. Correct the dimension arrow labeled ≈ fL on the left: it MUST run from the horizontal position of the CENTER OF AOM CRYSTAL (x approximately 600 in the 1536 image), all the way to the lens center (x1100). It must NOT begin at QWP. Leave the lens-to-mirror fL arrow unchanged. Also fix orange RETURN ray: from mirror it must lie immediately below the BLUE FIRST-ORDER ray by only 10 pixels, retracing the SAME upper lens region, then descend along the same sloping path back to AOM with arrowheads LEFT. It must NOT travel below the zero-order axis in lens-to-mirror segment. After AOM, keep return toward PBS offset below input for readability, then down to output. Relocate orange label \"第二程：+fRF\" if needed to avoid any ray overlap, but keep accurate wording. Preserve zero-order grey line and black beam stop. Keep everything else.","frequency":"Use case: scientific-educational. Create a NEW landscape 3:2 illustrated Chinese infographic explaining frequency accumulation in an AOM double-pass.

Place +fRF over each of the two arrows. A tiny curved mirror icon between the two AOM stages labeled \"反射返回\" suggests double traversal of the same crystal. These are chronological stages, not two physical AOMs on an optical bench. BELOW orange strip \"降频双程\": same three stages with \"ν₀\", \"ν₀ − fRF\", \"ν₀ − 2fRF\", arrows annotated −fRF. Each strip visually rich but uncluttered. Bottom two inset cards: left \"RF = 80 MHz\" then clear large \"双程频移 = ±160 MHz\"; right \"两次同号衍射\" and below \"总频移 = ±2fRF\". Small clear footnote \"时间顺序示意：两个 AOM 图标代表同一晶体的两次作用\". Ensure exact plus/minus values, no sine plots or invented data, no extra equations. Scientific diagram, NOT a marketing poster; prioritize precise short text and beautiful meaningful illustrations.","frequency_corrected":"Make only one precise correction to this infographic.

Three colored outgoing chief rays (green low RF, blue center RF, orange high RF) all start at SAME point O, slope upward with three different positive slopes, hit different heights on UPPER HALF of lens. AFTER lens all three rays must run EXACTLY HORIZONTAL, mutually PARALLEL, to the mirror. The mirror is normal to those rays. Draw small right arrowheads for outward rays and left arrowheads just adjacent to the exact SAME colored paths to indicate retracing. DO NOT draw downward returning rays or crossing rays. Lens height sufficient to cover all ray heights and clearly centered on optical axis. Labels above components \"AOM\", \"透镜 L\", \"反射镜 M\"; labels next to rays at mirror \"低 RF\", \"中心 RF\", \"高 RF\".

Bottom-middle card: green ray should also pass slightly above lens center and emerge horizontal slightly above grey axis.
