Time-lapse micrography records changes in a specimen by capturing a series of individual images at set intervals, which are then played back at a standard frame rate to reveal slow-moving processes that are otherwise imperceptible to the human eye.12

In modern microscopy, this process is facilitated by electronic detectors, such as charge-coupled device (CCD) or CMOS chips, which capture the magnified image as a digital signal. Software integrated with these systems allows the user to trigger time-lapse sequences automatically. By recording these images over time, researchers can observe developmental or biological changes in a specimen at an accelerated rate. Once captured, image processing can be applied to enhance the results, allowing for detailed analysis of particle size, distribution, and other physical or biological phenomena.312
