written directly for the practicing engineer or scientist.
Many textbooks and professional reference books cover
optical principles and techniques in depth. The aim of the
SPIE Field Guides is to distill this information, providing
readers with a handy desk or briefcase reference that
provides basic, essential information about optical principles, techniques, or phenomena, including definitions and
descriptions, key equations, illustrations, application
examples, design considerations, and additional resources.
A significant effort will be made to provide a consistent
notation and style between volumes in the series.
Each
SPIE Field Guide addresses a major field of optical
science and technology. The concept of these
Field Guides
is a format-intensive presentation based on figures and
equations supplemented by concise explanations. In most
cases, this modular approach places a single topic on a

page, and provides full coverage of that topic on that page.

Highlights, insights, and rules of thumb are displayed in
sidebars to the main text. The appendices at the end of
each

sidebars to the main text. The appendices at the end of
each
Field Guide provide additional information such as
related material outside the main scope of the volume, key
mathematical relationships, and alternative methods.
While complete in their coverage, the concise presentation
may not be appropriate for those new to the field.
The
SPIE Field Guides are intended to be living documents. The modular page-based presentation format
allows them to be updated and expanded. We are
interested in your suggestions for new
Field Guide topics
as well as what material should be added to an individual
volume to make these
Field Guides more useful to you.

小贴士

感谢您为本站写下的评论,您的评论对其它用户来说具有重要的参考价值,所以请认真填写。

  • 类似“顶”、“沙发”之类没有营养的文字,对勤劳贡献的楼主来说是令人沮丧的反馈信息。
  • 相信您也不想看到一排文字/表情墙,所以请不要反馈意义不大的重复字符,也请尽量不要纯表情的回复。
  • 提问之前请再仔细看一遍楼主的说明,或许是您遗漏了。
  • 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦,又没人会搭理,于人于己都无利。
