摘要： There is provided an actuator used in an optical system comprising a housing, a carrier disposed at least partly inside the housing, and a plurality of linear motion transducers coupled to the carrier and substantially evenly spaced around the carrier within the housing. Each linear motion transducer is able to produce linear motion when energized displacing the carrier relative to the housing to produce linear motion, tilting motion, or both of the carrier.

摘要： A method of sensing movement or proximity of objects by optical reflection is provided. The method includes the steps of transmitting a train of optical pulses towards a destination, sensing optical pulses reflected from the destination, and sensing and evaluating movement or proximity characteristics of objects at the destination with reference to variation in pulse width between transmitted and reflected optical pulses.
