【摘要】 <正> 一、引言一张全息照片,是由两束相干光波(物光波和参考光波)在记录介质中相互干涉而形成的。记录的是光波的干涉图样(或条纹)。这样的一张全息照片,就是一种衍射光栅。我们称它为“全息照片光栅”。以区别于一般特制的专用“全息光栅”。这两列相干光波,在记录介质中相迂时的夹角大小以及光波的性质(平面波或球面波)决定了全息底片光栅的性质,因而也决定了各种类型全息图的特征。一张全息照片既可是透射衍射光栅,也可是反射衍射光栅,或者既有透射衍射光栅,又有反射衍射光栅的复杂条纹更多还原

【Abstract】 A holographic-plate is a kind of diffraction grating that is called holographic-plate grating. The nature of holographic-plate gratuig determines the characteristics of all kinds of holograms. A holographic-plate grating can be a transmisscon-diffraction grating can be a reflectiondiffraction grating and can be a complex pattern with both transmissron diffraction gratings and reflection-diffractian gratings too. Thas making some holographic-plate gratings posses some peculiar characteristics. For inrtance a transmisscon-type holographic-plate can be reconstructed through reflection. Therefore in a holographic-plate grating can be generally observed the reconstraction of four images two in the transmission leams, two in the reflection leams. In practice, we also find and observe with great care the recanstruction of four reflection images when a transmission holographic-plate grating is reconstructed through reflection. That is to say, a holographic-plate has six reconstructed images in all on it. This arficle gives interpretations and analysis of their peculiar features observed.更多还原
