Abstract: The present invention discloses a laser tilt apparatus and the method thereof. The present invention comprises an input device, a tilt sensor, a motor, a microcontroller unit, and at least a laser module. The input device is used to input a tilt value. The tilt sensor supplies a tilt signal to represent the levelness of the laser tilt apparatus. The motor, electrically connected to the tilt sensor, adjusts the levelness of the laser tilt apparatus. The microcontroller unit samples the tilt signal to judge the levelness of the laser tilt apparatus. When leveling, the microcontroller unit drives the motor to adjust the tilt apparatus until the tilt signal matches the tilt value. After adjusting, the power supplied to the tilt sensor and the motor is suspended. The laser module is used to transmit laser light.

Abstract: A laser distance-measuring device includes a laser-transmitting portion, a laser-receiving portion, a coupling portion, an inclination-measuring portion, a signal-processing portion, and a display. The laser-transmitting portion emits a laser beam, and the laser-receiving portion receives the laser beam. The coupling portion interconnects the laser-receiving portion and the signal-processing portion. The inclination-measuring portion detects an inclination angle of the laser beam. The signal-processing portion processes the signals received from the laser-receiving portion and the inclination-measuring portion and sends the result to the display. The display receives and displays the result of processing by the signal-processing portion.

Abstract: A camera for measuring the distance to an object is combined with a laser range measuring device by using a beam splitting device so as to simultaneously take the image of the object and measure the distance between the camera and the object. Using the focal length of the lens, the width and height of the image on the image detector, and the distance between the camera and the object, it is then possible to compute the width and height of the object according to the geometrical optics. By means of obtaining the speed of the image moving on the image detector, the camera of the invention further computes the speed of the object which is projected on a plane perpendicular to the optical axis of the lens.

Abstract: A high precision laser range finder comprises an APC loop for eliminating a timing jitter problem due to different reflections on a target. The APC loop comprises a laser receiver, a peak holding circuit, an integrator and a high voltage generator. The peak holding circuit is connected with the laser receiver for detecting a signal strength outputted from the laser receiver. The high voltage generator provides the laser driver and laser receiver with voltage so as to control the strength of the emitted laser pulse signal of the laser driver and the gain of the avalanche photo-detector. The integrator is used to eliminate the steady error in the APC loop. Furthermore, a time to amplitude converting circuit comprises an AJD converter for obtaining a distance data and then filtering in a microprocessor to increase the measurement accuracy.
