An apparatus is disclosed for determining, in a first speed mode of operation, speed and range of a moving object and, in a second survey mode of operation, determining direct distances to an object and automatically calculate horizontal and vertical component distances to the object. Also disclosed is a system and method for data entry and retroactive reconstruction of the relative position of features and objects, in particular with respect to scenes such as transitory occurrences, utilizing a signal transmitting and receiving speed, distance and tilt angle determining apparatus or device. In a particular embodiment, the apparatus disclosed has especial applicability to tactical situation use by law enforcement personnel and the system and method in the on-scene recordation and subsequent ex post facto reconstruction of crime and traffic accident scenes by law enforcement officers. The system and method may be readily and efficiently implemented in conjunction with a laser-based speed, distance and tilt angle determining device otherwise usable for vehicle speed traffic monitoring functions utilizing either triangulation or baseline/offset mensuration techniques.

[ What is claimed is:] [1.] A hand held vehicle speed and object distance measuring apparatus comprising:a hollow housing;a signal transmitting and receiving device contained within said housing for transmitting and receiving a directed signal, said transmitted signal being directed toward each in a series of selected objects at a scene and receiving a reflected signal therefrom;a user aiming sight thereon for directing said transmitted signal; anda tilt angle sensor in said housing sensing a tilt angle of said transmitted signal, said tilt angle sensor having a neutral horizontal position and producing an electrical signal proportional to an inclination angle of said transmitted signal from said neutral horizontal position, said device being capable of determining a direct object distance and a horizontal distance to each of said series of selected objects based upon a time of flight of said transmitted signals directed to each one of said series of selected objects and reflected signals received from said each one of said series of selected objects and their respective tilt angles.
