The science and optical engineering of imaging Mueller Matrix Ellipsometry  (MME) and Spectroscopic MME is currently being revitalized based on an efficient  optimal design method, and through the use of the so-called Eig envalue Calibration Technique (ECT). Through the ECT one may efficiently measure the details of the polarization state generator (PSG) matrix, and the polarization  state analyzer (PSA) matrix, and hence avoid modeling of any unknown polarizing  components in the system, and in particular the exact response of complex  polarizing elements such as liquid crystal retarders. We here start up with  presenting a detailed an alysis of the dynamic response of a near infrared  Ferroelectric Liquid Crystal based Mueller matrix ellipsometer (NIR FLC- MME)  [1] . A time dependent simulation model, using the measured time response  of the individual FLCs, is used to describe the measured temporal response.  Furthermore, the impulse response of the detector and the pre-amplifier is  characterized and in cluded in the simulation model. The measured time  dependent intensity response of the MME is well explained by simulations. A FLC  based NIRMME system is here shown to be able to operate accurately at the  maximum speed of approximately 16 ms per Mueller matrix measurement (steady  state response). We demonstrate here time dependent Mueller Matrix  measurements of a dynamically changing sample, with even down to 8 ms  sampling time of each complete Mueller Matrix (with some loss of accuracy). We secondly briefly present the NIR-FLC- MME imaging system, and show  applications to strain imaging of a crystal subjected to an external pressure.  Furthermore, we present near-infra-red Mueller matrix images and corresponding  polar decomposition images of thin slices of bio-tissue [2]
