On the base of line element hologram, the recording and observing conditions of rainbow hologram of large scene depth without slit are discussed, and some rainbow holograms of large scene depth were recorded in our experiments.

从线全息图出发 ,讨论了获得大景深无狭缝彩虹全息图的记录和观察条件 ,并通过实验记录了大景深彩虹全息图。

The article analyses the line-element hologram width of zero-path-differencerainbow holography and suggests a way to make large scene depth rainbow hologram using zero path-difference rainbow holography.

根据对零光程差法彩虹全息的线全息宽度的分析，提出利用零光程差彩虹全息术获得大景深彩虹全息图的方法。

Experimental results indicate that the field depth of the wavefront coding system based on a single lens can be extended to 15 mm when the resolving power is 50 μm and the F number is 6, which is 4.

为了克服基于传统光学成像技术设计的手持式混凝土裂缝宽度测量系统焦深小、准确调焦困难,以及由于存在像差和混凝土表面凹凸过大致使视场内图像无法完全清晰等缺陷,采用波前编码技术重新进行缝宽检测系统的设计,以便有效地拓展景深(焦深)。

The fundamental optics of the formation of a photographic image and the factors influencing the picture clear ranges and field depth are explained, a detailed procedure is outlined and a series of practical directions are emphasized.

方法首先确定要拍摄的范围,即每一张照片具体要反映哪一段空间范围;然后选择镜头和机身、选定每一张照片的合适的拍摄点;最后用小光圈控制获得大景深。

The field depth is an important criterion for making the judgement of photograph quality.

景深对判断照片品质是一个很重要的标准。

There is very shallow depth-of-field in current iris recognition systems.

目前的虹膜识别系统中图像采集系统的景深非常有限,获取清晰虹膜图像需要用户的密切配合,这阻碍了虹膜识别系统的广泛应用。
