“…This alternative method was already used by Ichimoto et al [13] for a dual rotating compensator instrument with a single point detector. A similar procedure is also applied in instruments based on multiple photoelastic modulators [14]. It permits us to disclose the values the MM elements more straightforwardly, and it does not require the ratio ω 0 ∕ω 1 to be a rational number.…”

“…The experimental approaches to measure a complete MM can be classified according to the type of instrumental setup used for the measurement: using dual rotating compensators [12,13], four photoelastic modulators [14], two or more liquid crystal variable retarders [15], or beam splitters along with divisionof-amplitude method [16,17]. In principle, any of these four approaches can be applied to obtain complete MM measurements in different experimental arrangements: ellipsometers, scatterometers, transmission, and reflection microscopes.…”

In this paper we describe a new Mueller matrix (MM) microscope that generalizes and makes quantitative the polarized light microscopy technique. In this instrument all the elements of the MU are simultaneously determined from the analysis in the frequency domain of the time-dependent intensity of the light beam at every pixel of the camera. The variations in intensity are created by the two compensators continuously rotating at different angular frequencies. A typical measurement is completed in a little over one minute and it can be applied to any visible wavelength. Some examples are presented to demonstrate the capabilities of the instrument.

“…There are many types of instrumental setups used for time sequential polarization modulation, including rotating polarized optical components, 25,26 photoelastic modulators, 27 and liquid crystal variable retarder. 28 The photoelastic modulator is expensive, and the CCD detector that we used cannot take advantage of its high modulation speed.…”

Abstract. We have developed a polarization microscope based on a commercial transmission microscope. We replace the halogen light source by a collimated LED light source module of six different colors. We use achromatic polarized optical elements that can cover the six different wavelength ranges in the polarization state generator (PSG) and polarization state analyzer (PSA) modules. The dual-rotating wave plate method is used to measure the Mueller matrix of samples, which requires the simultaneous rotation of the two quarter-wave plates in both PSG and PSA at certain angular steps. A scientific CCD detector is used as the image receiving module. A LabView-based software is developed to control the rotation angels of the wave plates and the exposure time of the detector to allow the system to run fully automatically in preprogrammed schedules. Standard samples, such as air, polarizers, and quarter-wave plates, are used to calibrate the intrinsic Mueller matrix of optical components, such as the objectives, using the eigenvalue calibration method. Errors due to the images walk-off in the PSA are studied. Errors in the Mueller matrices are below 0.01 using air and polarizer as standard samples. Data analysis based on Mueller matrix transformation and Mueller matrix polarization decomposition is used to demonstrate the potential application of this microscope in pathological diagnosis. © The Authors.

“…Polarization can be modulated electronically by liquid crystals (LCs) or photoelastic modulators (PEMs), mechanically by rotating linear polarizers and quarter waveplates, and by diffraction using polarizing prisms, gratings, or graded index lenses. [59][60][61][62][63][64][65][66][67][68][69][70][71][72] In recent years, the field has witnessed many advanced designs and approaches, and there have been several demonstrations of using these novel systems for imaging biological tissues (Fig. 3).…”
