Science week activity "Eye movements and the problem of measuring in movement"
In this virtual activity of the science week Alberto de Castro Arribas will give a talk aimed at all audiences.
Our eyes are never completely stopped. Although we stare at something, they are always making small movements. These are hard to notice, but some examples will be shown in the talk so that attendees can see their own eye movements live.
Alberto will give a brief summary of what we know about these movements that at first glance seem random and will describe how they affect some of the measures we make. In the CSIC's Visual Optics laboratory there are devices that can measure the shape of the eye's surfaces with micron precision, but sometimes the system takes a certain time to perform the measurement. How can you measure something that is moving almost randomly? One strategy is to measure several times and calculate the mean, but we can ask ourselves: how many measures is appropriate? By simulating the experimental measurement with a computer, the influence of these movements can be calculated and strategies proposed to improve the results.
