    摘要： An endoscope comprising an elongate endoscopic structure having a distal end, a source of modulated light, means for illuminating with the modulated light a field of view from the distal end, an array of sensors, means for delivering to respective said sensors light reflected from discrete parts of the field of view, means for determining the relative times of arrival of the reflected light at the respective sensors and means for deriving from the relative times of arrival the relative distances of the discrete parts of the field of view from the distal end of the endoscopic structure.

    摘要： An identification device 10 comprises a retroreflector 12 for receiving an incident beam of radiation 14 from a detection unit 16 remote from the device and retroreflecting the incident beam back to the detection unit so that the device can be identified.
    The retroflector comprises a substantially spherical graded refractive index lens 20; a reflective part 22 for retroreflecting the incident radiation beam passing through the lens; and a tagging layer 24 disposed between the lens and the reflective part, wherein the tagging layer is selected to cause the retroreflected beam to comprise a spectrum of radiation which is characteristic of the device and which can be identified by the detection unit by comparison with a predetermined spectrum.
