Abstract
The utility model belongs to optical measuring appliance which specifically relates to a range finder which is characterized by using optical measurement and can realize high precision value. The range finder includes positioner and search apparatus and the characters includes: the positioner (1) is installed on main shaft (4) and can move relatively with thereof; the search apparatus (2) is installed on the main shaft (4) and can rotate around fixed latch (7) ; the positioner and search apparatus thereon are installed with telescopes and infrared emitter and using the positioner and search apparatus to lock target, the value of the distance measured can be gotten by measuring the length displayed in the scale area of the main shaft Iota. The utility model is suitable for operation in higher precision and special conditions.
Description
Technical field
The utility model belongs to the optical measurement apparatus, is specifically related to a kind of so that be the stadimeter of the realized high precision value of feature with measuring method.
Background technology
In the known technology, the scale registration that the measured value of optical range finder and precision are adjusted on light path and the difference gauge by micrometer is determined.Chinese patent application CN1055245U disclosed " electric wire height stadimeter " for example, this technical scheme realizes by the scale registration on micrometer adjustment light path and the difference gauge, but because the limited precision that influences measured value to a certain extent of precision of difference gauge has also limited remote measurement simultaneously.There is the surveying work of specific (special) requirements to make troubles.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, and processing ease can be realized the stadimeter of high precision value.
The utility model is taked following technical scheme.A kind of precision distance measurement instrument includes steady arm, search engine, and the utility model also is provided with: steady arm be installed on the main shaft and can with its relative motion, search engine is installed on the main shaft and can rotates around gim peg.Telescope and infrared transmitter are installed on steady arm and the search engine, and moving chi is installed on the main shaft can move on main shaft.I scale area and II scale area are set on main shaft, on moving chi, the III scale area are set.
Using method using method of the present utility model is such: when measuring length Y, rotate search engine, the length ratio that shows in length that shows in the III scale area in the triangle that adjustment search engine, main shaft and moving chi constitute and the II scale area is a suitable value K, uses the steady arm lock onto target.Mobile main shaft can capture search engine to be positioned the target of device locking, demonstrate length value X in the I scale area this moment, by similar triangles among Fig. 3 as can be known the value of tested length Y be Y=KX, cooperating application number is the value that 03214773.2 infinite precision is measured kind of calliper X, can improve the precision of tested distance Y theoretically to a great extent.
