Abstract
The invention relates to a device and a method for debugging emitter position of a ceilometer. The method comprises the following steps: (1) placing the emitter at a theory position of the focus of a lens so that the emitter emits light rays; (2) after a debugging plate generates reflecting light spots reflected by a plane mirror when light beams to be emitted pass through holes of the debugging plate and shine on the plane mirror, moving the plane mirror so that the light spots of different holes fall on the holes positioned on corresponding position of the debugging plate; (3) debugging the position of the emitter according to the relative positions of the reflecting light spots falling on the debugging plate so that the central positions of the reflecting light spots of the different holes are overlaid with the centers of the corresponding holes, the light spots are minimum, and the emitter is positioned at the focus position, i.e. an optimal placed position of the emitter of the ceilometer, of the lens at the time. The method which determines the focus position of the lens by measuring the size of an image has high precision, is convenient and easy to operate and can accurately determine the focus position of the lens, thereby determining the optimal placed position of the emitter.
Description
Technical field
The present invention relates to the optics debugging technique, be specifically related to the debugging apparatus and the adjustment method of a kind of lens focus position.
Background technology
For the emission beam spread angle that makes generating laser as far as possible little, behind transmitter, add lens, for making the emission parallel beam, transmitter need be put in the focus place of lens, and the real focal length of lens and theoretical value exist than mistake, so must determine the position of lens focus by a kind of reliable, high-precision adjustment method and debugging apparatus.
At present, adjustment method commonly used is to make a branch of light by parallel light tube, obtains a branch of directional light then, makes the directional light scioptics find the focus of these lens again.But light beams of different wavelengths focal position difference must be used the identical light beam of wavelength, and places transmitter and also there is certain error definite focal position.
Summary of the invention
The debugging apparatus and the adjustment method that the purpose of this invention is to provide a kind of reliable, high-precision lens focus position.
The technical scheme of the debugging apparatus of emitter position of ceilometer of the present invention is as follows: this device comprises cloud metre, be provided with transmitter and lens in the described cloud metre, this device also comprises debugging plate and the level crossing on the optical axis that places successively behind the lens, corresponding lens clear aperture position is provided with at least two holes with interior on the described debugging plate, and described debugging plate is placed with level crossing is all vertical with lens axis.
Corresponding lens position on the described debugging plate is an initial point with the optical center of lens, respectively with through the horizontal line of initial point and vertical line as the two-dimensional coordinate axle, and on this coordinate axis, mark coordinate.
It is the symmetrical hole of axis of symmetry with the lens axis that hole on the described debugging plate is two.
Kong Weisi on the described debugging plate is the symmetrical hole of axis of symmetry with the lens axis.
Kong Weiyi circular port and two rectangular openings that vary in size on the described debugging plate.
The step of the adjustment method of emitter position of ceilometer of the present invention is as follows:
(1) transmitter is placed the theoretical position of lens focus, make transmitter emission light;
(2) light beam to be launched is by the hole of debugging on the plate, and beats on level crossing, present the flare of flat mirror reflects on the debugging plate after, movable plane mirror, the hole that makes the hot spot in different holes drop on correspondence position on the debugging plate is located;
(3) drop on the position that the relative position on the debugging plate is debugged transmitter according to flare, the flare center in different holes is overlapped with the corresponding aperture center, and the hot spot minimum, this moment, transmitter was on the focal position of lens, that is to say the optimum position that the cloud metre transmitter is placed.
Described hot spot minimum promptly is a hot spot longitudinal length minimum up and down, left and right sides hot spot transverse width minimum.
Debugging apparatus provided by the present invention only needs transmitter, lens, debugging plate and level crossing with holes, is the device simple, practical, that cost performance is high.
The spot center that the position of adjustment method provided by the invention by the debugging transmitter makes flat mirror reflects with debug plate on the center of corresponding aperture overlap to determine the focal position of lens, convenient, the easy row of this method, and can determine the focal position of lens exactly, this focal position is exactly the optimum position that transmitter will be placed.
