Abstract
A photonic device including a filter comprising an electrically switchable array, wherein the electrically switchable array includes alternating layers of polymer and polymer-dispersed liquid crystal, wherein the electrically switchable array is tunable under an applied electric field.
Claims7
A photonic device including:
- a filter comprising:
- an electrically switchable array, wherein the electrically switchable array includes:
- alternating layers of polymer and polymer-dispersed liquid crystal, wherein the electrically switchable array is tunable under an applied electric field.
The photonic device of claim 4, wherein the filter is configured to:
- a) capture a color image when the filter is switched off;
- and
- b) capture a monochrome image when the filter is switched on.
A method of imaging, the method comprising:
- imaging a scene in a first frame with an Bayer filter to receive RGB values,
- imagine the scene in a second frame with the bayer filter turned off to receive light intensity values,
- converting the RGB values of the first frame to Y′CrCb values,
- removing the Y channel in the Y′CrCb frame to form a CrCb frame,
- subsampling the CrCb frame to form a subframe,
- combining the CrCb subframe and the second frame to reconstruct a final scene.
