ABSTRACT:
A shock resistant and mode mixing resistant assembly for oscillating a device such as a MEMS mirror around a pivot axis by means of two pairs of piezoelectric elements or towers is provided. The resistance to mechanical shock and mode mixing is accomplished by mounting the broad faces or width of each piezoelectric element in a chevron shape so that the broad faces or width dimensions are not in parallel or aligned with each other. Mounting the piezoelectric elements so that the broad faces or width dimensions are at a 15 degree angle with respect to a line perpendicular to the pivot axis has been found to be especially effective.
