摘要： An object of a galvanometer mirror of the present invention is to offer excellent driving characteristics in which when a mirror is driven to tilt, the center of torque acting on a moving body can be set in the vicinity of the center of the moving body. A mirror 6 is firmly fixed in a depression at the front of a rectangular frame-like mirror holder 18 constituting the moving body. First and second coils 21 and 22 are attached on the outer circumferential surface of the mirror holder 18 in the back-and-forth direction thereof at both sides of a plane passing through the center of gravity G of the moving body and parallel to the surface of the mirror. The moving body is rotatably supported by springs 23 so that a rotation axis 9 and another rotation axis orthogonal to the rotation axis 9 pass through the center of gravity G. Magnets 31 and 33 are fixed to a stationary magnet holder 14 so as to lie at the right and the left sides of the first coil 21 and the upper and lower sides of the second coil 22, respectively. With this configuration, the centers of torque D1-1 and D2-2 acting on the first and second coils 21 and 22, respectively when driving current is applied to the first and second coils 21 and 22 are set in the vicinity of the center of gravity G and the supporting point of the springs 23, thereby leading to improved driving characteristics.

摘要： Method and apparatus for linearizing the response of a mirror galvanometer or the like to a reference driving signal. An optical assembly transmits through a transmission grating a scanned light beam deflected from a reference signal driven galvanometer mirror. The beam passing through the grating is modulated thereby and received by a photocell. The transmission grating modulates the scanned beam in accordance with the velocity of scan of the light beam and the photocell produces an output signal having a freqency content corresponding to the velocity of the beam. An electrical circuit, in response to the frequency content of the photocell output signal, produces a control signal which is combined with the reference driving signal and applied to the galvanometer to deflect the galvanometer mirror in a manner linearly related to the reference driving signal.

摘要： This disclosure describes an improved high frequency liquid damped galvanometer. It differs from conventional galvanometers in that the damping tube that confines the damping liquid is of larger diameter and of greater length so that the major portion of the galvanometer coil is emersed in the damping liquid and there is restricted clearance between the coil and the damping liquid tube. Because of the proximity between the mirror and the liquid surface, means are provided for restricting the migration of the damping liquid up the coil to the mirror surface, by coating the internal surface of the top portion of the damping tube and the top portion of the coil with a fluorinated resin. This coating is not wetted by the oily damping liquid so that there is no creeping of liquid up to the mirror, which is mounted above the tube by attachment to the top spool of the coil. Another improvement of this invention lies in the adhesive material by which the mirror is attached to the top spool. The adhesive is of a special composition in which the epoxy adhesive is mixed with at least twice its weight of inert non-hygroscopic powder. When this mixture hardens there is much less shrinkage then is found in the epoxy cement alone, and there is therefore less distorting force on the mirror, which more nearly maintains its true planar surface.

摘要： A vibrating coil assembly for mirror galavanometers, light-beam oscillographs and the like having a mirror and a moving coil suspended by taut wires or ribbons. The ends of the wires nearest the moving coil are provided with eyes and a mounting wire is brought through the eyes and a window in the moving coil to form a figure 8 and clamp the moving coil within it. A stiffening tube for receiving the mirror is pushed over a section of the wire adjacent to one eye. The stiffening tube is cast together with the moving coil and the mounting wire by means of a setting compound.

摘要： A specific galvanometer structure, designed to maximize the coil/mirror inertia torsional resonance and the inductance/inertia resonance, includes a galvanometer coil and a mirror integrally bonded therewith. The coil itself acts as the mechanical beam for the mirror, and is made of many layers of anodized aluminum ribbon bonded together with epoxy. Increasing the cross-sectional width of the coil raises the coil/mirror inertia torsional resonance but lowers the inductance/inertia resonance. Accordingly, optimized operating frequency occurs when the two resonant frequencies are equal. A drive circuit coupled to the coil via a flexure-pivot coil suspending means, produces a current pulse doublet of the same form as the acceleration desired at the mirror.
