Abstract
The present invention relates to an apparatus for low coherence optical imaging, and more particularly to an apparatus for low coherence optical imaging which can obtain the information of the different depths of a sample simultaneously. The apparatus comprises a phase transformation unit or a beam shift unit. The phase transformation unit or beam shift unit transforms and reflects the reference light, such that the reflected reference light comprises different phases at the different positions of a cross-section. When the reference light and a information light from the sample are superimposed on a photo detector, the information of the different depths of the sample is obtained. By using the apparatus of the present invention, the elements, the volume, and the cost of the apparatus are reduced. Because of only two-dimensional scanning is required, the scanning rate is improved.
