They use bifringent plates the same way any other anti-low pass filter works; a binfringent material creates a vertical blur, then the light goes through the IR filter, then another bifringent material is used that is opposite to the first one, thusly "bringing it all back together."  In a normal OLPF they use a bifringent material, then a 1/4 wave or 1/2 wave plate to bring the light back into phase, then another bifringent material rotated 90deg to get a "perfect" blur.
