Experimental Study of Optical Force Measurement Techniques

Mentor:
Research Theme: Energy
FURI: Summer 2020

The objective of this project is to experimentally measure the optical force reflected by a sample using two methods of measurement. One tuning fork-based and one laser-cantilever optical force measurement system were developed in order to quantify the optical force by two means: an oscillating probe from which distinct frequencies can be measured, and a change in deflection measured by a position-sensitive detector, respectively. The measured force will serve as a basis for the understanding and implementation of a particle-repellent coating for electronics and space exploration technologies.

Experimental Study of Optical Force Modulation using Tunable Materials

Mentor:
Research Theme: Energy
FURI: Spring 2020

The objective of this project is to experimentally measure the optical force reflected by a sample with tunable optical properties such as vanadium dioxide. A tuning fork based optical force measurement system was developed in order to quantify the optical force by an oscillating probe from which the resulting resonant frequency shift can be measured. The measured fluctuation of force will serve as a basis for the understanding and implementation of a particle-repellent coating for electronics and space exploration technologies.
