Interphasic scanner

An interphasic scanner, or simply IP scanner, was a sensor device used aboard Starfleet vessels in the 24th century, for use in detecting objects which existed in a state outside normal visual and sensor acuity.

In 2370, Doctor Beverly Crusher used a handheld IP scanner to reveal an infestation of interphasic organisms aboard the USS Enterprise (NCC-1701-D). Later, Lieutenant Worf used an IP scanner to inspect the area around the Enterprise in an attempt to find more evidence of the organisms.
