PMD system and method for distance measurement of an object |
摘要 |
<p>The system has intensity modulated transmission units (3, 3`, 3``) arranged at different positions relative to an object (1). A photonic mixer device (PMD)-receiver (4) receives signals transmitted by the transmission units and reflected from the object. A central modulation unit (5) produces a common modulation signal for the transmission units. Phasing of the modulation signal is individually changed for the transmission units in such a manner that equal distance values of the object are determined with each transmission unit. An independent claim is also included for a method for distance measurement of an object by using a photonic mixer device (PMD)-system.</p> |
