Mobile microscope

摘要

Microscope sensor is directed at in situ particle movement within a dispersed substance, e.g. emulsions, aerosols, dust, foam, bubble distribution. The in-situ microscope has pulse illumination generated by one or more light-emitting diodes. The image is detected by e.g. a standard charge-coupled device video camera of standard light sensitivity and without a light amplifier. The LEDs are subjected to a pulse electrical supply which is of an order above that of the manufacturer's nominal rated value (of e.g. 10 A). The pulse duration is precisely set to a period of e.g. 0.3 microns to obtain short exposure times and extend LED service life.
