Abstract
An imaging spectro-polarimetry system includes a polarizer, a tunable laser, a number of optical nodes and an image processing circuit. The polarizer produces polarized light using light received from an object. The tunable laser generates optical local oscillator (LO) signals. Each optical node receives the polarized light and an optical LO signal, performs a heterodyne mixing and generates a digital signal. The image processing circuit receives digital signals from the optical nodes and generates a magnetogram of the object. The polarizer, the tunable laser, the plurality of optical nodes and the image processing circuit are implemented on a photonic integrated circuit (PIC), and the polarized light includes right and left circularly polarized light.
