Abstract
Abstract A stabilized binocular using a gimbaled and stabilized triple-reflecting compensator (such as in Humphrey U.S. Patent 3,475,073) having three reflecting surfaces for each binocular path is disclosed. Each of the binocular paths is in convergent light from an objective to and through gimbaled stabilizer assembly to a primary focus that is stabilized with respect to the case. The triple-reflecting surfaces disposed to reflect light in the manner corresponding to a single plane mirror at an effective mirroring plane with a displacement between the incident and reflected light beams. The compensator remains stabilized with respect to inertial space, while the instrument undergoes accidental angular motion. The reflecting property of the compensator brings the image back to the same place on the case despite the accidental angular motion. The displacing function of the compensator , enables the image to be displaced to a location where the image does not interfere with the incoming light path. This image is then processed by conventional field optics, including a zoom relay lens: Provision is made to adjustable compensate for displacement and resultant angular velocity, acceleration, and jerk. Resonance is naturally avoided as torquing forces are not applied where inertial centering of the compensator is sufficient.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
An optical instrument comprising: a beam splitter (313), first and second oculars (E L , E R ) first and second respective ocular paths (303', 304') from said beam splitter (313) to said oculars (E L , E R ), one of said ocular paths (303', 304') from said beam splitter (313) to one ocular (E L , ER) being longer than the other ocular path (303', 304') from the beam splitter (313) to the other ocular (E L , E R ), said longer ocular path including means (307) for reducing the effective length of the path thereof from the beam splitter (313) to the ocular (E L , E R ).
Claim 2
Dependent Claim
113 words
An optical instrument comprising: a beam splitter (313), first and second oculars (E L , E R ) first and second respective ocular paths (303', 304') from said beam splitter (313) to said oculars (E L , E R ), one of said ocular paths (303', 304') from said beam splitter (313) to one ocular (E L , ER) being longer than the other ocular path (303', 304') from the beam splitter (313) to the other ocular (E L , E R ), said longer ocular path including means (307) for reducing the effective length of the path thereof from the beam splitter (313) to the ocular (E L , E R ).
Claim 3
Dependent Claim
33 words
The instrument of claim 1 wherein said means (307) for reducing the effective length of the path includes an optical material in said path for providing a change in the index of refraction.
Claim 4
Dependent Claim
157 words
An optical instrument comprising: a beam splitter (313), and two light paths thereto including one finder light path (312) and one magnified light path (311), first and second ocular paths (303', 304') from said beam splitter (313) to said first and second oculars (E L , E R ) respectively, one of said first and second ocular paths (303', 304') from said beam splitter (313) to one of said first and second oculars (E L , E R ) being longer than the other one if said first and second ocular paths (303', 304') from the beam splitter (313) to the other one of said first and second oculars (E L , E R ) said longer ocular path (303', 304') including means (307) for reducing the effective length of the path thereof from the beam splitter (313) to the one of said first and second oculars (E L , E R ) associated with said path.
Claim 5
Dependent Claim
157 words
An optical instrument comprising: a beam splitter (313), and two light paths thereto including one finder light path (312) and one magnified light path (311), first and second ocular paths (303', 304') from said beam splitter (313) to said first and second oculars (E L , E R ) respectively, one of said first and second ocular paths (303', 304') from said beam splitter (313) to one of said first and second oculars (E L , E R ) being longer than the other one if said first and second ocular paths (303', 304') from the beam splitter (313) to the other one of said first and second oculars (E L , E R ) said longer ocular path (303', 304') including means (307) for reducing the effective length of the path thereof from the beam splitter (313) to the one of said first and second oculars (E L , E R ) associated with said path.
