Tohoku University Technology: Holographic optical element and its manufacturing method: T17-106
Conversion of depth information linearly into planar information!
In 3D imaging, it is important to effectively encode z information, which is the image formation displacement of the target object, into XY information, which is displacement from the optical axis of the image surface. On the other hand, in single-pixel imaging using only a single detector, it is important to encode in efficient manner the XY information of the target into the time information. However, the conventional encoding method has a limit on distance resolution, imaging distance range, z information decoding accuracy and encryption uniqueness. This invention provides a new and improved hologram optical element, its manufacturing method and an optical device able to mutually convert Z & XY information with simple configuration. This invention is able to realize high accuracy and high spatial resolution for high-speed 3D imaging (patent US10816474) by converting the object depth direction information of the optical detection system into the planar direction information at the detecting surface.
