Abstract
A polarized light microscope includes a light source configured to illuminate a specimen and an imaging sensor configured to capture an image of the specimen. The polarized light microscope also includes a first circular polarizer positioned between the light source and the specimen. A birefringent mosaic mask is positioned between the specimen and the imaging sensor. The polarized light microscope also includes a second polarizer positioned between the mask and the imaging sensor.
Claims20
A polarized light microscope comprising:
- a light source configured to illuminate a specimen;
- an imaging sensor configured to capture an image of the specimen;
- a first circular polarizer positioned between the light source and the specimen;
- a birefringent mosaic mask positioned between the specimen and the imaging sensor;
- and
- a second polarizer positioned between the mask and the imaging sensor.
An instant imaging full Stokes polarimeter, comprising:
- a polarization image sensor that includes a polarizer and an imaging sensor;
- a birefringent mosaic mask proximate to the polarization image sensor, wherein the birefringent mosaic mask includes a plurality of birefringent superpixels, and wherein each birefringent superpixel is formed of one or more pixels with no birefringence and one or more birefringent pixels;
- and
- a processor operatively coupled to the polarization image sensor, wherein the processor is configured to process a plurality of intensity signals generated by the plurality of birefringent superpixels to identify Stokes parameters of an image captured by the imaging sensor.
