Abstract:
1. A handheld optical distance measurement device, the device comprising: a distance measurement engine; an angular position measurement engine; and a controller that controls the distance measurement engine and associates one of an elevation, azimuth position, or relative angular position from the angular position measurement engine with distance measurements taken from the distance measurement engine; memory for storing the distance measurements from said distance measurement and the one of an elevation, azimuth position, or relative angular position from said angular position engine; an algorithm stored in said memory for calculating measurements that depend upon both of the distance measurements from said distance measurement and the one of an elevation, azimuth position, or relative angular position from said angular position engine; a user interface including a display that can display elevation and distance of a measurement taken of a target, and an input keypad that permits a user to select device operations; a visible pointing indicator that permits a user to point an indicator beam at a target.
