A method and apparatus for locating various entities, including animate human beings and animals, as well as inanimate objects, such as, for example, certain types of plastics, observes and detects a force and subsequent resulting torque, acceleration, vibration or other measurable quantifiable manifestation of the force created by the non-uniform three-dimensional electric field spatial gradient pattern exhibited uniquely by the entity or object. Incorporation of laser energy enhances detection. Specifically, the inclusion of laser radiation enhances a dielectrokinetic effect by creating a localized region of significantly higher dielectric constant via absorption of the laser radiation by the air, and other properties which in turn significantly increases the dielectrophoretic force and resulting torque, and lowers the response time by preferentially directionally orienting or channeling the non-uniformity of the electric field line generated by the entity or object target towards the laser beam region. The laser's effect enhances the operational performance of dielectrokinetic detection devices by improving the range of detection, the strength of force and resulting torque manifestation in the locator device, and the ultimate speed of the locator device.
