光學掃描全像之三維顯影技術

Experimental Animal Manipulation and Application: Taking the Measurement of Isolated Aortic Vasocontraction and Vasorelaxation for Example

光學掃描全像術為一種基於外差干涉、二維掃描與單畫素擷取的數位全像攝影技術。光學掃描全像術具有一些傳統數位全像術所沒有的特點，包括可拍攝非同調全像、光瞳調控全像、融合全像、以及傾斜式全像等。在本文中我們將介紹光學掃描全像術的原理以及幾個重要的特點，並且將介紹光學掃描全像術在三維顯影方面的相關技術。 Optical scanning holography(OSH) is a kind of digital holography. OSH applies the techniques of heterodyne interference, two-dimensional scanning, and single-pixel detection. In addition, OSH has some unique features, including the recordings of the incoherent hologram, the pupil-modulation hologram, the fusion hologram, and the tilted hologram. In this article, we will introduce the principle and features of OSH. Techniques of OSH for three-dimensional imaging will also be discussed.
