The passive dampers act to passively dampen the motion of the optics assembly on the xy plane within the actuator module during optical image stabilization (ois) of the optics assembly when subjected to external excitation or disturbance, and may also provide z (optical) axis damping and impact protection.

Optical measuring isolated features of a structure


An optical method and system are presented for use in measurement of isolated features of a structure. According to this technique, back focal plane microscopy (bfm) measurements are applied to a structure and measured data indicative thereof is obtained, wherein the bfm measurements utilize dark-field detection mode while applying pinhole masking to incident light propagating through an illumination channel towards the structure, the measured data being thereby indicative of a scattering matrix characterizing scattering properties of the structure, enabling identification of one or more isolated features of the structure..
