Device for distance measurement

摘要: A device for measuring distance with a visible beam (11) generated by semiconductor laser (10), has collimator object lens (12) to collimate the towards optical axis (13) of (12), an arrangement modulate radiation, reception (15) receive and image reflected from distant (16) on receiver, switchable deflection (28) generate internal reference path between (10) receiver electronic evaluation (25) find display measured object. According invention, contains light guide (17') downstream opto-electronic transducer (24), in which inlet surface (17) is arranged imaging plane long distances can be controllably moved (18') this position (18) transversely (14). In alternative embodiment, fixed there are means (36) outside (14) which, short distances, deflect (15). The radiation pulse modulated excitation pulses width less than two nanoseconds.
