A slide assembly includes a first slide member having a guiding base and a lock portion, a second slide member having a first slide segment and a second slide segment, a third slide member movably mounted on the second slide segment, an aid-sliding member slidably connected between the first slide member and the first slide segment, and a positioning device connected to the second slide member. The photo detector responses are digitized and stored as a frame into memory. In this way, the memory access time delays associated with the transfer of data amongst the CPU-groups can be advantageously reduced while the ability to more effectively utilize the total number of available CPUs in the processing of the program threads is advantageously increased. The dual stage actuation flexure further comprises a pair of motors mounted on the gimbal and a pair of stiffeners respectively mounted on the motors. The optical fibers are suitable for multimode operations.
