This article describes some recent results obtained by the author and his group by applying visualization and opto-imaging measurement to various convection phenomena. The results presented include those related to index-matching stereo particle image velocimetry (PIV), 3-D particle tracking velcimetry for thermocapillary convection, micro fluorescent particle surface velocimetry, dynamic PIV, stereo direct-imaging for particle measurement, micro-imaging displacement meter for dynamic surface displacement and electronic speckle pattern interferometry. Although those techniques cover only a limited area in this field, they provide an idea on the current status and the future direction of this field.
