phase contrast

基本解释

This "phase contrast" signal gives much clearer and detailed results.
这种“相差”信号提供更为清晰和详细的结果。
The resolution of Darkfield and Phase Contrast Microscopy is up to 10-500A.
暗视场及相衬显微术的分辨率可达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”.
经过培训的卫生工作者利用双盲交叉法对震荡试验和被视为“黄金标准”的相衬显微术的效果进行对比。

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.
