Abstract: Determining the survival rate of avian embryos during incubation is essential for cost-saving in the poultry industry. A multichannel diffuse speckle contrast analysis (DSCA) system, comprising four optical fiber channels, is proposed to achieve noninvasive in vivo measurements of deep tissue flow. The system was able to monitor chick embryo vital signs over the entire incubation period. Moreover, it proved useful in distinguishing between chick embryos in healthy and weakened conditions. ©2015 Optical Society of America.
