Abstract We report an experimental demonstration of temporal ghost imaging in which a digital micromirror device (DMD) and $+1/-1$ binary modulation have been combined to give an accurate reconstruction of a nonperiodic time object. Compared to the $0/1$ modulation, the reconstruction signal can be improved greatly by $+1/-1$ binary modulation even with half of the measurements. Experimental results show that $0/1$ binary temporal objects up to 4 kHz and sinusoidal time objects up to 1 kHz can be reconstructed by this method. The influences of modulation speed and array detector gray levels are also discussed.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
