要远离打鼾，我们要先知道鼾声从何而来。当人入睡后，颈部肌肉逐渐放松，导致上呼吸道变得狭窄，无法让足够的空气进入肺部。由于气体流通受阻，当人吸气和呼气时，上呼吸道周围的软组织就会产生振动，形成鼾声。气道越窄，振动幅度越大，鼾声就越大。另外，鼻中隔偏曲、鼻息肉、下颌短小，以及舌头或扁桃体肥大等，都会引发打鼾。

「封面解读」基于像差校正的光强传输定量相位成像技术：南京理工大学和合作单位研究者提出了一种高通量成像技术——基于像差校正的光强传输定量相位成像。该技术融合了像差校正与超分辨率成像，可适配大像素尺寸传感器以实现宽视场成像，并将成像分辨率提升至两倍。该成果有望在生物医学和癌症诊断等具有高通量成像需求的领域得到广泛应用。
