Highly robust single-round detection for computational ghost imaging based on orthogonal bases.

In computational ghost imaging experiments, negative elements in the orthogonal patterns are not able to be projected by the projection device and are often imaged by doubling the measurements, thus reducing the imaging efficiency. We validated several commonly-used orthogonal patterns using a single-round measurement scheme and investigated the effect of different noise intensities on the single-round measurement scheme. The results show that smaller noise does not have a significant effect on the reconstruction results of the single-round measurement scheme, and the negative value of the orthogonal measurement basis can be solved using the single-round measurement scheme.
