ABSTRACT:
A laser beam profile sensor system for which is capable of accurately determining distances to both close and distant objects, particles, liquid interfaces and the like and of identifying the locations of ice layers on metal surfaces. Basically, the system includes a laser diode for generating a laser beam along a selected path, a receiver spaced from the laser diode for receiving light along a receiver axis, the laser beam and receiver axis intersecting at any desired angle from nearly 0.degree. to nearly 180.degree.. The receiver comprises a linear array of light responsive elements. An optical system is provided for directing light approaching the receiver along the receiver axis to the array. An electronic circuit processes signals from the array elements and produces a display showing the distance to any target lying along the laser beam path that reflects light along the receiver axis.
