Laser optical trap – Jason Miller – 2011

Jason Miller (2011 Physics graduate) constructed, calibrated, and utilized an optical trap in order to observe micro-scale phenomena.  This type of system is also known as ‘optical tweezers’ for its capability to hold and move micro- and nano- sized objects.  Optical tweezers are created by focusing a laser through a high numerical aperture objective, forming a ‘trap’ at the focal point of the objective.  The result is a ‘cage’ that can hold nano- and micro- sized particles and can be used for a large number of applications in physics, chemistry and biology.  Advisor: Dr. Changgong Zhou (czhou@ltu.edu).
