Abstract
Apparatus and methods are disclosed for measuring polarization properties and phase information, for example as can be used in microscopy applications. According to one example of the disclosed technology, an apparatus includes a light source, an interferometer configured to receive light generated by the light source and split the received light into two split beam outputs. The split beam outputs including combined, interfering light beams. Two light sensors, each including a polarization-sensitive focal plane array receive a respective one of the split beam outputs from the interferometer. Thus, some examples of the disclosed technology allows for simultaneous or concurrent measurement of properties of light including intensity, wavelength, polarization, and phase. The polarization-sensitive focal plane array includes a number of macropixels, each of which includes superpixels having different polarization filtering properties, each of which includes one or more pixels, which comprise filters for different colors.
