摘要: A new method based on four photoelastic modulators (PEMs) and a charged couple device (CCD) camera, to rapidly image the samples' entire Mueller matrix, is proposed optimized. The full imaging of matrix elements using time-gated technique synchronized with PEMs' modulation demonstrated. Evolutionary algorithm employed choose 16 time points, from which ele- ments can be recovered minimized sensitivity noise. suitability several configurations PEMs different frequencies opti- cal axes for discussed through numerical examples. ability perform in millisecond range improved SNR absence mechanically moving parts should prove advantageous polarimetric characterization biological tissues. © 2013 Society Photo-Optical Instrumentation Engineers (SPIE) (DOI: 10
