    Patent number: 4669874
    Abstract: In the present invention, a support positions a target within the field of view of the borescope. The target is in the focal plane of the borescope and contains a series of parallel images of progressively finer detail. The image having the finest detail which is detectable by the borescope gives a measure of the borescope's resolving power.
