Description

A kind of luminous energy collimator

Technical field

The utility model relates to optical technical field, specifically a kind of luminous energy collimator.

Background technique

Autocollimator is for small angle measurement or to can be exchanged into one kind of small angle measurement using optical autocollimating principle Common metrology and measurement instrument.Autocollimator usually can spectroscopy autocollimator and photoelectric auto-collimator two major classes: 1) optical self-calibrating Straight instrument: directly minimum from readout value, precision on graticle or reading drum using micrometer device or movable graticle；2) photoelectricity Autocollimator: replacing artificial sight line to line with photoelectronic collimating, is that accuracy of measurement is higher in autocollimator, developing history is shorter One kind.

Photoelectric auto-collimator is the product that auto-collimation technology is combined with photoelectric technology, because its accuracy of measurement is higher, makes It is widely used with succinctly facilitating.Photoelectric auto-collimator is born in the 40-50 age, and auto-collimation technology can be traced earlier when Phase.It is widely used in angle measurement, guide rail the depth of parallelism and flatness measurement, the roughness measurement of table top, precision positioning, from Dynamic angle positioning ring is integrated etc., is the departments such as machine-building, shipbuilding, aerospace, metrology and measurement, scientific research indispensability Conventional measuring equipment.Especially in terms of accurate, Ultra-precision positioning, more there is irreplaceable role.Into the eighties, especially Since the nineties, with the rapid development of Novel Optoelectronic Device and computer technology, classical auto-collimation technology has shone blueness again Spring.Number display replaces drum reading, and twin shaft measurement replaces uniaxial measurement, and Novel Optoelectronic Device replaces photodiode, photosensitive Resistance, and mostly by standard interface, such as RS232 is connected with computer is directly acquired data by computer and gone forward side by side line number According to processing.The resolving power of instrument, repeatability, accuracy index have increased substantially.

Currently, can produce the country of photoelectric auto-collimator in the world mainly has Britain, Germany, the U.S., Japan etc., and consult Data learns that it is German MOLLER company production that precision is highest in the photoelectric auto-collimator introduced to the market at present ELCOMATHR and ELCOMAT3000, the photoelectric auto-collimator of both models are all made of the line array CCD of high resolution as light Electric explorer.The autocollimator in China is started in the thirties, and photoelectric auto-collimator is developed in the seventies.Currently, in the market more Advanced is the AUTOMAT5000 type autocollimatic instrument of Tianjin Ao Te the Mearl Corporation production, using line array CCD as photoelectric sensor Precision is higher, has reached international most advanced level, has broken such product of developed country to a certain extent in the monopolization in China, but Whether from resolving power, measurement range or from the point of view of precision, there is larger gaps with foreign countries.

Photoelectric auto-collimator and optics, precision machinery, microelectronics subject etc. are closely bound up.The limitation of optical processing technology makes The product quality of photoelectric auto-collimator is restricted；It is this using weak light sources, light energy wretched insufficiencies such as incandescent lamps in terms of light source Under the conditions of lead in most situations that heliogram is faint, cause image quality bad, it is difficult to distinguish compared between close-target Difference generates wrong data, leads to serious consequence.

Therefore, for the above status, lower, measured zone that there is an urgent need to develop a kind of solution prior art intermediate-resolutions compared with It is small, precision is poor, light source selection is limited and image quality poor (especially in the dusk and night because of dark, this situation is more Obviously) the luminous energy collimator of problem, to overcome the shortcomings of in currently practical application.
