摘要：
A method and apparatus for generating three-dimensional image information is disclosed. The apparatus includes a lens having a single imaging path operable to direct light captured within a field of view of the lens to an aperture plane of the lens. The apparatus also includes a polarizer located proximate the aperture plane, the polarizer including a first portion disposed to transmit light having a first polarization state through a first portion of the single imaging path and a second portion disposed to transmit light having a second polarization state through a second portion of the single imaging path, the first and second portions of the single imaging path providing respective first and second perspective viewpoints within the field of view of the lens. The apparatus further includes a modulator disposed in the single imaging path, the modulator being operable to selectively change a polarization state of light passing through the modulator to alternate between forming a first image through the first portion of the single imaging path and forming a second image through the second portion of the single imaging path, the first image representing objects within the field of view from the first perspective viewpoint and the second image representing the objects from the second perspective viewpoint, the first and second images together being operable to represent three dimensional spatial attributes of the objects.茲揭示有一種用於產生三維影像資訊之方法和設備。該設備係包含具有一單一成像路徑之一透鏡，可操作以將在該透鏡之一視野內所捕捉的光導引至該透鏡之一孔徑平面。該設備係亦包含位於該孔徑平面附近之一偏光板，此偏光板係包含一第一部分和一第二部分，其中該第一部分係經佈置以將具有一第一偏光狀態之光傳送穿過該單一成像路徑之一第一部分，且該第二部分係經佈置以將具有一第二偏光狀態之光傳送穿過該單一成像路徑之一第二部分，該單一成像路徑之第一部分和第二部分係在該透鏡之視野內提供各別的第一透視點和第二透視點。該設備係進一步包含經佈置在該單一成像路徑中之一調變器，該調變器操作上係選擇性改變通過該調變器之光的一偏光狀態，以在透過該單一成像路徑的第一部分形成一第一影像和透過該單一成像路徑的第二部分形成一第二影像之間交替進行，該第一影像係代表在該視野內來自該第一透視點的物件而該第二影像係代表來自該第二透視點的物件，該第一影像和該第二影像一起係可操作以代表該等物件的三維空間屬性。
