Improving the throughput of automated holographic optical tweezers
Applied Optics, 2018 The purpose of this work is to introduce three improvements to automated holographic-optical-tweezers systems that increase the number and speed of particles that can be manipulated simultaneously. First, we address path planning by solving a bottleneck assignment problem, which can reduce total move time by up to 30% when compared with traditional ...

Combined holographic-mechanical optical tweezers: Construction, optimization, and calibration
Review of Scientific Instruments, 2009 A spatial light modulator (SLM) and a pair of galvanometer-mounted mirrors (GMM) were combined into an optical tweezers setup. This provides great flexibility as the SLM creates an array of traps, which can be moved smoothly and quickly with the GMM.

Experimental demonstration of holographic three-dimensional light shaping using a Gerchberg-Saxton algorithm [PDF]
, 2005 We use a three-dimensional Gerchberg–Saxton algorithm (Shabtay (2003) Opt. Commun. 226 33) to calculate the Fourier-space representation of physically realizable light beams with arbitrarily shaped three-dimensional intensity distributions.
