time-shared amplifier

A combination of 50 fs cross correlation time gating and lock in amplifier detection is shown to be a versatile technique to image objects through various highly scattering medium.

利用50fs互相关时间选通门和锁相放大相结合，成功地实现了对埋藏在不同散射介质中的物体进行透射式成像。

At the same time this kind of material is also the best material for high fidelity magnetic head, high performance magnetic amplifier.

同时这种材料也是高灵敏度保真磁头、高性能磁放大器元件的最佳材料。
