DETAILED DESCRIPTION To this end, the present invention is directed toward an elongated, flexible, tubular inspection instrument characterized as having a control head at its proximal end and an objective assembly at its distal end.
Fiber optics extend between the control head and the objective assembly for the purpose of transmitting to the control head an image viewed from the distal end.
Appropriate optics located at the objective assembly include an image conversion means which can be manipulated at the control head to provide, rapidly in succession, either a forward looking view or a sideward looking or lateral view.
The sideward looking view is always at a positively positioned predetermined angle from the forward looking view, and vice versa.
Therefore, a principal feature of the present invention resides in its capability of changing the observing direction, at any time, at the will of the operator, by providing a reflecting member rotatably mounted at the distal end, and on the object side of, the inspection instrument.
Another feature of the present invention resides in the ability of the inspection instrument to selectively change the observing direction by providing a rotatable reflecting member at the distal end for providing optical illumination as well as a reflecting member for the optical observation system such that both reflecting members are rotated in a unitary fashion.
Still another feature of the present invention resides in the ability of the inspection instrument to utilize a fiber optical bundle in a most efficient manner so as to permit the largest diameter possible of a bundle in keeping with the diameter of the instrument system.
Still another feature of the invention resides in its various fail safe expedients which assure the integrity of those parts of the system which are inside a cavity to be inspected.
Other and further features, objects, advantages, and benefits of the invention will become apparent from the following description taken in conjunction with the following drawings
