摘要:
An encoder element (1) with high spatial resolution comprising an information layer with optically readable information, wherein the information is in the form of successive pits (10) written in by a laser beam and wherein the pits possess a specific optical property that substantially differs from that of the surrounding surface of said information layer.
摘要:
An imaging system with optically butted CCD sensors (26, 27a, 27b), and means for determining the spacial position of such sensors comprising a beam splitter (33) with mounting surfaces (46, 47) for the different sensors, and mounting members (62, 64, 69. 70, 71, 72) with a base surface and a supporting surface extending truly rectangularly thereon, the base surfaces being adhesively bonded to the mounting surfaces of said beam splitter and the supporting surfaces being adhesively bonded to lateral surfaces of the corresponding linear sensors.
