phase contrast

基本解释

This "phase contrast" signal gives much clearer and detailed results.
這種“相差”信號提供更爲清晰和詳細的結果。
The resolution of Darkfield and Phase Contrast Microscopy is up to 10-500A.
暗眡場及相襯顯微術的分辨率可達10～500（?）
A double-blind crossover design was used to compare the performance of the shake test conducted by trained health-care workers (HCWs) with that of phase contrast microscopy as a “gold standard”.
經過培訓的衛生工作者利用雙盲交叉法對震蕩試騐和被眡爲“黃金標準”的相襯顯微術的傚果進行對比。

In contrast,a light bulb has much more impact in the use phase, where it's using the energy, and where you can reduce that with more efficient lighting technologies,"

Even the advanced two-stage focusing system has made its way from the T4i, which utilizes both phase-difference and contrast AF in order to achieve focus more efficiently when capturing video.

The F900EXR automatically switches between Phase Detection AF and Contrast Detection AF depending on the subject and scene, guaranteeing superb ease-of-use and fast, accurate autofocus no matter what the setting or shooting conditions.

Photo Rumors hears the two shooters will switch to a newer, faster hybrid (both contrast and phase detection) focusing system that also includes Sony NEX-style manual focus peaking, which provides a rough visual guide as to when a subject is as sharp as possible.

A differential phase contrast wave-front sensing system based on an optical addressed ferroelectric liquid crystal spatial light modulator (OA-FLCSLM) is introduced, different from the traditional phase contrast method which is highly sensitive to the wave-front tilt.
