For the holographic recording of the wave field of an object, a pattern created by the interference of the reference wave and the wave scattered by the object is used. Traditional holography requires mutual coherence of the reference and object-related beams. However, it has been shown in this work that the holographic recording of information concerning the object under study is possible without coherence between them, even by using radiation from different sources. Such recording can be carried out by employing subcycle or unipolar radiation pulses, when a resonant medium with a large phase memory time T₂ is used as the recording medium. In this case, the medium records the interference pattern formed by the subcycle or unipolar pulse reflected from the object and the polarization wave created by the same short pulse. Coherence is ensured by a polarization wave, which interacting with radiation reflected from the object induces a population grating in such a medium. This grating mimics the interference pattern in a similar holographic process with a monochromatic source having the wavelength equal to that corresponding to the resonant transition in the medium.

在参考光束和被物体散射的光束之间没有相干性的情况下进行全息记录的可能性

对于物体的波场的全息记录，使用了由参考波和物体散射的波的干涉产生的图案。传统的全息术要求参考光束和与物体相关的光束相互相干。然而，在这项工作中已经表明，即使通过使用来自不同源的辐射，也可以全息记录与研究对象有关的信息，而无需它们之间的连贯性。当具有大的相位存储时间T ₂的谐振介质时，可以通过使用子周期或单极辐射脉冲来执行这种记录被用作记录介质。在这种情况下，介质记录由对象反射的子周期或单极性脉冲形成的干涉图样以及由同一短脉冲产生的偏振波。偏振波可确保相干性，该偏振波与从物体反射的辐射相互作用会在这种介质中感应出种群光栅。该光栅在类似的全息过程中模仿干涉图样，其单色源的波长等于介质中共振跃迁的波长。
