The microscope includes an image capture circuit including an array of optical sensor. An optical arrangement is configured to direct excitation light of less than about 1 mW to a target object in a field of view of that is at least 0.5 mm 2 and to direct epi-fluorescence emission caused by the excitation light to the array of optical sensors. The optical arrangement and array of optical sensors are each sufficiently close to the target object to provide at least 2.5 μm resolution for an image of the field of view.
1. A method comprising:

6. A method according to claim 1 , further comprising sequentially acquiring an optical signal from the pre-defined area at the optical sensor array through a combination of a first portion of the optical excitation arrangement with an optical spectral filter at a frequency rate sufficient to track cellular dynamics at said pre-defined area.
