Multiarray Independent Dynamic Polarization Control Device

To address the Air Force need for projection system polarization control for calibration and evaluation of surveillance and interceptor sensors in space simulation chambers, Physical Optics Corporation (POC) proposes to develop a new Multiarray Independent Dynamic Polarization Control Device (MADPOD). This proposed device is based on the tunable electro-optic effect of infrared nonlinear crystals. The innovations of integration of infrared nonlinear crystals into the dynamic polarization control device, and the architecture of the device in the space simulation chamber will enable MADPOD to change any state of polarization into any particular polarization defined by the user (or the sensor under test); it can work in a cryo-environment with a response time <1 ms and independently manipulate the polarization state of a 512x512 pixel array. It has a wide wavelength range and broadband operation (near infrared to long wavelength infrared). In Phase I POC will demonstrate the feasibility of MADPOD by assembling and testing a proof-of-concept prototype. In Phase II POC plans to develop and demonstrate a fully functional engineering prototype that will meet Air Force needs for test applications; its high reliability is based on solid-state polarization control with no mechanical movement.
