Zebrafish Circadian Clock Entrainment and the Importance of Broad Spectral Light Sensitivity
Frontiers in Physiology, 2020 One of the key defining features of an endogenous circadian clock is that it can be entrained or set to local time. Though a number of cues can perform this role, light is the predominant environmental signal that acts to entrain circadian pacemakers in ...

Phase-shift extraction for phase-shifting interferometry by histogram of phase difference
Optics Express, 2010 We propose a non-iterative approach to extract the unknown phase shift in phase shifting interferometry without the assumption of equal distribution of measured phase in [0,2π]. According to the histogram of the phase difference between two adjacent frames, the phase shift can be accurately extracted by finding the bin of histogram with the highest ...
