Abstract
A laser receiver (1) for acoustically indicating a laser beam, including a housing (4), a detector unit (6) that ascertains the actual position (2) of the laser beam, an evaluation unit (8) that determines the difference between the actual position (2) and the target position (3), and an acoustic indication device (7) that uses an acoustic signal to indicate whether the actual position (2) of the laser beam is above, below or at the target position (3), wherein a control unit (9) is provided that, as a function of the difference between the actual position (2) and the target position (3), generates a scanning signal to modulate a basic signal, and then sends the scanning signal to the acoustic indication device (7).
Claims7
A method for acoustically indicating a laser beam, the laser beam being received in an actual position on a detector, the method comprising:
- determining a difference between the actual position and a target position using an evaluation unit;
- and
- employing an acoustic indicator to indicate whether the actual position of the laser beam is above, below or at the target position, a basic signal being modulated with a scanning signal, the scanning signal being changed as a function of the difference between the actual position and the target position;
- wherein a scanning ratio and/or scanning frequency of the scanning signal is changed as a function of the difference between the actual position and the target position.
A method for acoustically indicating a laser beam, the laser beam being received in an actual position on a detector, the method comprising:
- determining a difference between the actual position and a target position using an evaluation unit;
- and
- employing an acoustic indicator to indicate whether the actual position of the laser beam is above, below or at the target position, a basic signal being modulated with a scanning signal, the scanning signal being changed as a function of the difference between the actual position and the target position, wherein a scanning ratio and/or scanning frequency of the scanning signal is changed as a function of the difference between the actual position and the target position,
- wherein the scanning ratio and/or the scanning frequency of the scanning signal are changed continuously or in several discrete stages, as a function of the difference between the actual position and the target position.
A laser receiver for acoustically indicating a laser beam, comprising:
- a housing;
- a detector ascertaining an actual position of the laser beam;
- an evaluator determining a difference between the actual position and a target position;
- and
- an acoustic indicator using an acoustic signal to indicate whether the actual position of the laser beam is above, below or at the target position;
- and
- a controller generating, as a function of the difference between the actual position and the target position, a scanning signal to modulate a basic signal, and sending the scanning signal to the acoustic indicator;
- wherein the acoustic indicator has an electric signal generator, a first electro-acoustic sonic converter and a second electro-acoustic sonic converter, the signal generator and the first sonic converter being arranged in the housing, the second sonic converter connectable to the signal generator via a communication connection.
