Alignment mirror mechanisms for space use

2011 Aerospace Conference, 2011
The paper describes an optical Alignment Mirror Mechanism (AMM), and discusses its control scheme. The mirror's angular positioning accuracy requirement is ± 0.2 arc-sec. This requires the mirror's linear positioning actuators to have a positioning accuracy of ± 109 nm to enable the mirror to meet the angular tip/tilt accuracy requirement. Demonstrated

Multiple mechanisms for the detection of mirror symmetry

Spatial Vision, 1995
Symmetry detection was investigated for static and dynamic noise targets consisting of a field of approximately 0.3 million random dots on which was imposed a bilateral symmetry. The minimum duration for detection was 40 ms for static and 80 ms for dynamic symmetry.

UTLNet: Uncertainty-Aware Transformer Localization Network for RGB-Depth Mirror Segmentation

IEEE transactions on multimedia
Mirror segmentation, an emerging discipline in the field of computer vision, involves the identification and marking of mirrors in an image. Current mirror segmentation methods rely on fixed mirror elements as features for object segmentation.

Mirror movements: mechanisms, diagnosis, and emerging therapeutic strategies

Acta Neurologica Belgica
Mirror movements (MM) are involuntary, symmetrical motor actions that accompany voluntary movements of the opposite limb, arising from disruptions in corticospinal tract function and interhemispheric communication. While physiological MM occur transiently in early childhood, persistent MM are pathological and may be congenital, linked to genetic ...
