The computational optics group (COG) was formed in 1999 as a division of applied optics laboratory, institute of applied physics, university of Tsukuba. On that moment we were not COG but spatio-temporal optics group, and our main research subject was spatio-temporal optical computing.
In 2000, we started a optical measurement project using spatio-temporal optical computing technologies, and in 2002, we changed our direction to more computationally.
Since 2002, our main research interest is computer assisted optical measurment. We are trying to introduce computational technologies into optical measurement.
Since 2007, we are an independent research group and no longer a part of Applied Optics Laboratory of University of Tsukuba.
