    Abstract: Methods and apparatuses for finding, extracting and for providing of echoes with detail functions are described. In particular, an echo extraction method for extracting an echo (109, S1, max1, max2, max3, e1, e2) from an echo function (100, 500, 2900, 4900) is described. The method comprises receiving the echo function (100, 500, 2900) and decomposing the echo function in at least one detail function (D1, D2, D3, D4, D5, D6, D7, D8, D9), wherein the at least one detail function (D1, D2, D3, D4, D5, D6, D7, D8, D9) comprises a plurality of first coefficients (2902). Each of the at least one detail functions (D1, D2, D3, D4, D5, D6, D7, D8, D9) represents a different degree of detail of the echo function (100, 500, 2900), wherein the degree of detail relates to a form of a base function (700, 900, 1000, 1100, 1200, 1805, 2600, 2700, 3501, 3506). Furthermore, the method comprises eliminating at least one of the plurality of first coefficients (2902) and applying a reconstruction regulation or scheme, which depends on the form of the base function, for generating a smoothed echo function (2901). Thereafter, at least one echo (109, S1, max1, max2, max3, e1, e2) is determined from the smoothed echo function (2901).

    Abstract: Technology is disclosed for measuring distances. A measurement device emits a beam that reflects on the surface of an object. The measurement device determines the distance to the object, based on the time of flight of the beam from transmission to capture by the measurement device. The device includes a light source adapted to provide an outgoing reference beam. A detector is aligned to receive a return beam, wherein said return beam results from a reflection of said outgoing reference beam from an object outside of said distance measurement device. A diffuser is provided adjacent to the detector aligned to receive said return beam.

    Abstract: Disclosed is a laser rangefinder and method thereof. By using characteristics that noise has non-correlation and signals have correlation, laser beams are output to a target to find a range to the target with iteration rates of thousands of times per second, signals for each range-finding are binary-quantized using a sampling frequency corresponding to a range-finding resolving power, and data are accumulated. After this, the accumulated data are processed in a statistical manner to detect a target signal and produce a target range based on the target signal. According to the present invention, the rangefinder for outputting low-power laser beams, using the laser beams reflected from the target, and detecting a range to the target, easily and accurately detects target signals in the noise.

    Abstract: A reflected laser pulse (23) is received by a detector (34) which is a single component of a detector array (30). The reflected laser pulse is then amplified by an amplifier (36) and sent through a matched filter (38) to optimize the signal-to-noise ratio. A data sampler (40) takes samples of the reflected laser pulse (23) and stores the data samples within a temporary data storage (42). A comparator (44) compares each data sample in the temporary data storage (42) to a predetermined threshold constant to determine if the threshold constant has been exceeded. When the threshold constant is exceeded, the data from the temporary data storage (42) is sent to a buffer (48) where it is held while an analog-to-digital converter (50) digitizes the samples for use by a computer (26) in identifying an object and determining the location of the detected object. The identity and location of the detected object are displayed on a display device (32).
