具有极高灵敏度的数字全息

Digital holography with ultimate sensitivity

Michel Gross, Michael Atlan

摘要:

我们提出了一个变体的外差全息计划,结合了离轴和相移全息的属性。该方案可以在数字上滤除参考信号的零阶图像混叠和技术噪声。这样就有可能在极低的信号电平下记录和重建全息图像。我们的实验表明,该方法的灵敏度是有限的,仅由光子的量子性质。

英文摘要:

We propose a variant of the heterodyne holography scheme that combines the properties of off-axis and phase-shifting holography. This scheme makes it possible to filter off numerically the zero-order image alias and the technical noise of the reference. It is then possible to record and reconstruct holographic images at an extremely low signal level. We show experimentally that the sensitivity of the method is limited only by the quantum nature of photons.
