Abstract: This paper is the first review of haptic optical tweezers, a new technique which associates force feedback teleoperation with optical tweezers. This technique allows users to explore the microworld by sensing and exerting picoNewton-scale forces with trapped microspheres. Haptic optical tweezers also allow improved dexterity of micromanipulation and micro-assembly. One of the challenges of this technique is to sense and magnify picoNewton-scale forces by a factor of 10(12) to enable human operators to perceive… Show more

“…6,20 Normally, the detection of forces and displacement of objects in multiple optical traps is done by means of a camera, because it has been difficult to separate the signals from the multiple laser beams using photodiodes. With this spatial filtering, it should be possible to separate the signal from each trap and detect it individually with a photodiode, which has distinct advantages over camera detection, e.g., higher temporal and spatial resolution 21,22 as well as easier data analysis. Hence, we believe the presented signal filtering scheme will prove quite useful for future more accurate optical tweezers experiments.…”

“…Nowadays, the measurement of the position and the orientation are obviously a main topic for nanometrology. It may concern the positioning of nano-object to manipulate them [1] but also the positioning of macro-object like sample-holder or macro-tools. Resolutions up to the nanometer or tens of picometers are now achieved thanks to the sensors which have been developed.…”

“…However, in comparison to photodiode detection, this implies reduced spatial and temporal resolution, offline data processing, higher costs and limited axial detection capability. On the positive side, camera based detection easily allows for monitoring many particles in parallel [15][16][17]. To improve the axial detection capabilities of multi-trap camera based imaging, stereoscopic imaging [18,19] and point spread function engineering [20] have been presented.…”
