light slit method的意思|示意

Rainbow holography is a major method in white-light holography, which is lack of vertical parallax due to introducing a slit that reduces the view zone of reconstructed images in recording process.

利用彩虹全息是实现白光全息的常用方法，由于记录过程中引入狭缝使得再现像的视场非常狭小，且只有水平视差。

This paper discussed a method analyzing the two-step rainbow hologram. Based on the diffraction theorem of light wave, the imaging formulas of object image and slit image were derived in detail.

本文讨论了一种分析二步法彩虹全息的方法，用光波衍射理论详细推导出物体象与狭缝象的成象公式。
