<p><span>安森美半导体 (ON Semiconductor，美国纳斯达克上市代号：</span><a href="http://www.onsemi.cn/PowerSolutions/ir.do"><span>ON</span></a><span&gt;)，</span><span>今天发布新的RDM系列</span><a href="https://www.onsemi.cn/products/sensors/silicon-photomultipliers-sipm?ut…;硅光电倍增管 (SiPM)</span></a><span><span>&nbsp;</span></span><span>阵列，将激光雷达 (LiDAR</span><span>)<span>&nbsp;</span></span><span>传感器能力扩展到</span><span>其</span><span>广泛的智能感知方案阵容。</span><a href="https://www.onsemi.cn/products/sensors/silicon-photomultipliers-sipm/rd…;是市场上首款符合车规的SiPM产品，应对汽车行业及其他领域</span><a href="https://www.onsemi.cn/solution/automotive/adas-viewing-autonomous-vehic…;应用中不断增长的需求。</span><span><span>&nbsp;</span></span></p>

<p><a href="https://www.onsemi.cn/products/sensors/silicon-photomultipliers-sipm/rd…;是单片1×12 SiPM像素阵列</span><span>，</span><span>基于</span><span>安森美半导体</span><span>领先市场的RDM工艺，可实现对近红外</span><span><span>&nbsp;</span>(</span><span>NIR</span><span>)</span><span><span>&nbsp;</span>光的高灵敏度，从而在905纳米</span><span>(</span><span>nm</span><span>)</span><span>处达到领先业界的18.5％</span><span>的</span><span>光子</span><span>探</span><span>测效率</span><span><span>&nbsp;</span>(</span><span>PDE</span><span>)</span><span><span>&nbsp;</span></span><span>(</span><span>1</span><span>)</span><span>。SiPM的高内部增益使</span><span>其</span><span>灵敏度</span><span>可</span><span>达</span><span>到</span><span>单光子水平，该功能与高PDE结合使用，可以检测最微弱的返回信号。</span><span>因此，</span><span>即使</span><span>是低</span><span>反射目标，也</span><span>能探</span><span>测</span><span>到</span><span>更</span><span>远</span><span>的距离。</span></p>

<p><a href="https://www.onsemi.cn/products/sensors/silicon-photomultipliers-sipm?ut…技术</span></a><span>近年来发展势头强劲，由于其独特的功能集，已成为</span><span>广阔</span><span>市场深度传感应用的首选传感器。SiPM能在明亮的阳光条件下进行长距离测距时提供最</span><span>佳</span><span>的信噪比性能。其他优</span><span>势</span><span>包括</span><span>较</span><span>低的电源偏置和</span><span>较低的</span><span>温度变化敏感性，使其</span><span>成为</span><span>使用传统雪崩光电二极管</span><span>(</span><span>APD</span><span>)</span><span>的系统</span><span>的理想升级产品</span><span>。SiPM采用大批量CMOS工艺生产，可实现最低的</span><span>探</span><span>测器成本，</span><span>从而</span><span>实现</span><span>应用于广阔</span><span>市场的</span><a href="https://www.onsemi.cn/solution/automotive/adas-viewing-autonomous-vehic…;方案。</span></p>

<p><span>使用激光测量物体的距离已跨越了汽车</span><span>、</span><span>消费和工业应用领域。在汽车</span><span>领域</span><span>，</span><a href="https://www.onsemi.cn/solution/automotive/adas-viewing-autonomous-vehic…;可用于</span><span>提升</span><span>安全性和驾驶员辅助系统</span><span>(</span><span>ADAS</span><span>)</span><span>，通过与其他感</span><span>知模</span><span>式互补</span><span>和</span><span>提供冗余</span><span>，</span><span>辅助如车道保持和交通拥堵辅助等功能。LiDAR正</span><span>普遍</span><span>用于全自动驾驶</span><span>的</span><span>使用</span><span>案</span><span>例</span><span>，例如机器人运输，以安全地实时导航环境。</span><span>受益于</span><a href="https://www.onsemi.cn/products/sensors/silicon-photomultipliers-sipm/rd…;的高PDE，支持这些功能的LiDAR系统已</span><span>被</span><span>证</span><span>明可在</span><span>300米</span><span>以上的距离测距</span><span>。更</span><span>远</span><span>的距离使车辆有更多时间来应对意外障碍。</span></p>

<p><span>安森美半导体汽车感知分部高级总监</span><span>Wade Appelman<span>&nbsp;</span></span><span>说：“</span><span>LiDAR提供的高分辨率深度数据可在充满挑战的</span><span>微</span><span>光条件下即时准确地识别物体。<span>&nbsp;</span></span><a href="https://www.onsemi.cn/products/sensors/silicon-photomultipliers-sipm/rd…;是</span><span>首</span><span>款符合</span><span>车</span><span>规</span><span>的SiPM，将提供远</span><span>距离、</span><span>高性价比的LiDAR方案</span><span>，以</span><span>实现</span><span>下一层次</span><span>的安全和自</span><span>主</span><span>性。</span><span>我们</span><span>正不断加强我们的传感器组合，</span><span>提供多样</span><span>化</span><span>且互补的</span><span>感知</span><span>模式，</span><span>为</span><span>更高</span><span>级别</span><span>的</span><a href="https://www.onsemi.cn/solution/automotive/adas-viewing-autonomous-vehic…和自动驾驶</span></a><a href="https://www.onsemi.cn/solution/automotive/adas-viewing-autonomous-vehic…;铺平道</span></a><a href="https://www.onsemi.cn/solution/automotive/adas-viewing-autonomous-vehic…;路</span></a><span>。</span><span>”</span></p>

<p><span>Yole技术与市场分析师Pierrick Boulay说</span><span>：“</span><span>Yole Développement<span>&nbsp;</span></span><span>(</span><span>Yole</span><span>)</span><span>将LiDAR视为实现汽车全自</span><span>主化</span><span>的</span><span>一个</span><span>关键组成部分，其功能必须达到2+及</span><span>以上</span><span>级别。 生产</span><span>符合</span><span>车</span><span>规</span><span>并具有足够性能水平的传感器，将成为汽车应用大规模采用LiDAR的关键推动力，根据目前的趋势，</span><span>预计</span><span>在2019年至2025</span><span>(</span><span>2</span><span>)</span><span>年之间的复合年增率为+144％。</span><span>”</span></p>
