Optical characterization of the PALM-3000 3388-actuator deformable mirror [PDF]
, 2010 We describe the lab characterization of the new 3,388-actuator deformable mirror (DM3388) produced by Xinetics, Inc. for the PALM-3000 adaptive optics (AO) system1 under development by Jet Propulsion Laboratory and Caltech Optical Observatories.

Programmable unitary spatial modes manipulation
, 2010 Free space propagation and conventional optical systems such as lenses and mirrors all perform spatial unitary transforms. However, the subset of transforms available through these conventional systems is limited in scope.

Advanced Functional Materials, EarlyView.The pre‐internalization phase of endocytosis remains poorly characterized at single‐cell levels. Single‐cell pre‐internalization mechanics are investigated using advanced robotic techniques. Cancer cells exhibit biphasic adhesion – rapid initial binding followed by reinforcement – while fibroblasts show gradual engagement.

Development of a unimorph deformable mirror with water cooling.
Optics Express, 2017 Deformable mirror (DM) used for intracavity compensation in high-power lasers should be able to withstand very high laser intensity. This paper proposes a water-cooled unimorph DM which can withstand the laser power up to 10 kW in thermal simulation. The

Optimizing (1‐x) BiFeO3‐xCaTiO3 Perovskites: A Pathway to Efficient Flexible Energy Storage
Advanced Functional Materials, EarlyView.Perovskite materials, like BFO CTO, are popular due to their high conductivity, low cost, and wide availability. In this work a symmetric electrochemical cell based on BFO‐CTO shows a charge of 3.356 C.cm⁻2, giving a specific capacitance of 2.79 mF.cm⁻2 at 1 mV.s⁻2.

Research on a bimorph piezoelectric deformable mirror for adaptive optics in optical telescope.
Optics Express, 2017 We have proposed a discrete-layout bimorph piezoelectric deformable mirror (DBPDM) and developed its realistic electromechanical model. Compared with the conventional piezoelectric deformable mirror (CPDM) and the bimorph piezoelectric deformable mirror (

Advanced Functional Materials, EarlyView.Wrinkling of soft materials, such as polydimethylsiloxane (PDMS), underpins a myriad of technologies. Plasma‐oxidation of PDMS induces spontaneous wrinkling, which is canonically attributed to thermal expansion‐contraction of bilayers. Employing experiments and modelling, it is demonstrated that sorption of water vapor is instead responsible for ...
