Force measurement with an optical trap requires calibration of it. With a suitable detector, such as a position-sensitive detector (PSD), it is possible to calibrate the detector so that the force can be measured for arbitrary particles and arbitrary

We review the basic theory and principles of optically driven micromachines, and present a series of simple heuristic principles for designing such micromachines. We discuss the relationship between symmetry and optical torque, and consider technique
