Abstract
A light detection and ranging (LIDAR) device includes a pixel, a mirror, and a birefringent material. The pixel is configured to emit light having a first polarization orientation. The mirror is configured to reflect the light to a surface. The birefringent material is disposed between the pixel and the mirror. The birefringent material introduces an offset in a position of the emitted light having the first polarization orientation propagating through the birefringent material. The birefringent material shifts a reflected beam in space horizontally back on the pixel.
