Publikováno v: Optics and Precision Engineering. 20:1877-1882

In consideration of the crosstalk between reconstructed image and zero-order image existed in the digital reconstruction for off-axis digital holography,this paper presents a method to suppress the zero-order image.Based on the principle that the pix

Publikováno v: ACTA PHOTONICA SINICA. 40:1542-1546

A novel method for the acquisition of full-color three dimensional(3-D) images of real objects was proposed based on multiple projections.In order to improve sampling efficiency,an orthogonal scanning mode was presented,instead of conventional 2-D sc
