Compact flexible multi-pass rotary delay line using spinning micro-machined mirrors

Fleddermann, Roland; Lee, W. M. Steve; Huang, Keshu; Campbell, Geoff; Lam, Ping Koy; Chow, Jong


We propose a new method to extend the path length tunability of rotary delay-lines. This method was shown to achieve a duty cycle of >80% and repetition rates of over 40 kHz. The new method relies on a new multi-segmented micro-machined mirror and serial injection of a single reflection onto separate segments of this mirror. The tunability is provided by the relative positioning of each reflective point on the mirror segments. There are two distinct modes of operation: synchronous and...[Show more]
