<p>then estimating the fluorescence on unstained samples. Thus by decoupling the cells under investigation from the cells used to train the network, imaging can performed quicker and with reduced phototoxicity.</p>

<p>The wave nature of light limits the size of the spot to which light can be focused due to the <a href="page.php?w=diffraction_limit">diffraction limit</a>. This limitation was described in the 19th century by <a href="page.php?w=Ernst_Abbe">Ernst Abbe</a> and "limits an optical microscope's resolution</p><p>
