Ranging basic principles can be attributed to the need to measure light from the target time, then the speed of light c = 299792458m / s and atmospheric refractive index n calculated distance D. More difficult due to the direct measurement of time, usually measured continuous-wave phase, called the test-phase range finder. Of course, there are pulse range finder, typically WILD's DI-3000. Note that the measured phase is not a measurement of the phase infrared or laser, but measurements in the infrared or laser modulation signal phase above. Construction industry has a hand-held laser range finder for measuring housing, it works the same way. Usually requires total reflection prism with precision ranging, and measured with the rangefinder housing directly to a smooth wall reflection measurements, mainly because of relatively close distance, the light intensity of the reflected signal is large enough. With this you can know, be sure to vertical, otherwise the signal is too weak will not be accurate distance. Usually possible, the actual project will use a thin plastic plate as a diffuse reflector to solve a serious problem. Ultrasonic ...
... Ranging accuracy is relatively low, is now rarely used. Laser rangefinder accurate to 1 mm error, for a variety of high-precision measurement applications. The after service of one-year repair will be supplied for green laser pointer. Level models are beginning to DS, are "earth" and "water level" in pinyin first letter, usually omit to write the letter D. Followed by "05", "1", "3", "10" and other numbers indicate the accuracy of the instrument. S3-and S10-level water level water level, also known as common for our country three or four other standards and common standards of measurement, S05 and S1-level class called Level Precision Levels for the national one, second precise leveling: Electronic level also known as digital levels, it is automatically on the basis of the development of Anping Level up. It uses bar code ruler, the ruler of the manufacturers of bar code pattern is not the same code can not be used interchangeably. Currently awarded for visual scale and focus needed. After completion of sighting and manual focus, scale bar on the one hand by imaging in the differentiation of the board telescope for visual observation, the other through the telescope of the spectroscope, scale bar has been in the optical imaging sensors (also known as the detector ), namely, linear CCD device for electronic reading. Some technical parameters of 100mW green laser pointer have been adjusted before shipping.  green laser pointer  has passed the strict testing. green laser pointer needs the maintenance and inspection. Hand-held laser range finder laser range finder and the telescope sub-type laser range finder. Hand-held laser range finder: measuring distance is 200 meters, the accuracy of about 2mm. This is the most widely used laser range finder. In addition to measuring the distance function, in general, but also to calculate the measurement of body volume. Laser range finder binoculars: distance is measured in 600-3000 meters, measured from a distance such rangefinder, but the accuracy is relatively low, usually about 1 meter accuracy. Major applications for the field long distances. 50mW green laser pointer range finder used in topography measurements, measurement of the battlefield, tanks, aircraft, ships and artillery on the target distance, measuring clouds, planes, missiles and satellite height. It is to improve the high tanks, aircraft, ships and artillery accuracy of important technical equipment. As the laser range finder prices continue to drop, the industry gradually began to use the laser range finder, can be widely used in industrial monitoring and control, mining, ports and other areas. 200mW green Laser Pointer is very popular in the current market.
