Description

This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018) Abstract Holographic Optical Tweezers (HOT) are a versatile way of manipulating microscopic particles in 3D. However, their ease of use has been hampered by the computational load of calculating the holograms, resulting in an unresponsive system. We present a program for generating these holograms on a consumer Graphics Processing Unit (GPU), coupled to an easy-to-use interface in LabVIEW (National Instruments). This enables a HOT system to be set up without writing any additional code, as well as pro... Title of program: Red Tweezers Catalogue Id: AEQH_v1_0 Nature of problem This program controls a holographic optical tweezers instrument, including GPU-accelerated rendering of holograms, monitoring the video feed and presenting a user-friendly interface to manipulate particles.
