The low-voltage driving circuit is adopted to drive a piezoelectric ceramic phase shifter to shift the phase of the reference beam, so as to make the instrument lighter, smaller and cheaper.

采用低压驱动电路驱动压电陶瓷相移器对参考光束进行相移，从而使仪器质量减轻、体积缩小、成本降低。

If a beam similar to the original reference beam is shone through a hologram, the result is a three-dimensional image of the object scanned.

ECONOMIST: Researchers can now broadcast moving holograms

When the reflected object beam and the reference beam are recombined, they create an interference pattern that encodes the 3-D image.
