When a laser beam is focused into a volume of highly absorbing thermal medium, gas bubbles can be generated due to the temperature change caused by the laser. In our previous work, it has been shown that these optically generated microbubbles can be

In our previous work, digital holographic topography has been used to investigate the depth pattern of different surfaces. Two-wavelength digital holography has been used to resolve depth variations on surfaces, which are in the order of several micr

Applications of Digital Image Processing XLI.
A hologram is the 2D recording of the amplitude and phase of an object. Often the phase contains the information of the depth of a 3D object. In our previous work, the 3D mapping of different surfaces have been performed using digital holographic top

Optical Trapping and Optical Micromanipulation XV.
Nonlinear absorption of laser radiation focused on a volume of a highly absorbing thermal medium creates a temperature difference and induces a refractive index change inside the medium. It has been shown that gas bubbles can be generated by increasi

Laser-based Micro- and Nanoprocessing XII.
Forces acting on thermally generated microbubbles are studied by deriving a general force model. Microbubbles can be steered by moving the laser beam. In previous work, it has been shown that the attractive thermo-capillary force on the microbubble i

Polarization Science and Remote Sensing VIII.
Polarization measurements can be used to distinguish different objects. In this work, polarimetry has been used as a useful tool to differentiate between two geometries, viz., a cube and a cylinder, demonstrating that polarization “signatures” ca

In our previous work, the induced force on a microbubble due to a focused laser beam has been studied by deriving a general optical force model. It has also been shown that the microbubble, without and with agglomerated metallic nanoparticles, can be

Calculating the net optical force on particles that are enclosed by a sphere, requires rigorous mathematical steps and consumes more time. Also it is complex to compute the total force on particles that are on a sphere. As a result, the easy approxim
