2020年12月11日 · 该检测方法与零位补偿器检测法相同，通过计算全息图的光学波前被全息条纹衍射成为一束相位被“整形”的光学波前，变成与待测光学表面形状一致的光学波前，实现零位补偿功能， 为光学元件面形检测提供了全新的零位检测手段。 由于计算全息是依赖于微电子加工技术的一种衍射光学元件，因此其加工精度极高，相应零位补偿精度也得到保证，因此能够实现各类曲面的实时高精度检测。 在之前，CGH一直被业界认为是高精尖领域才能应用的技术，成本高昂 …

Channel 16 VHF (156.800 MHz) is a marine VHF radio frequency designated as an international distress frequency. [1] Primarily intended for distress, urgency and safety priority calls, the frequency may also carry routine calls used to establish communication before switching to another working channel.
