Abstract
The present invention provides a method for forming a light house. The method comprises the steps that light beams which are emitted by a light source and spread along a direction being parallel to the land surface or a horizontal surface are converted into cylinder parallel light beams through a collimator, and then, the light beams are reflected through a taper mirror with a taper angle of 90 degrees so as to form a light wall which is vertical to the land surface or the horizontal surface; light beams which are emitted by the light source and spread along the direction being vertical to the land surface or the horizontal surface are converted into cylinder parallel light beams through the collimator simultaneously, and then, the light beams are reflected by a taper mirror with a taper angle of 90 degrees so as to form a light wall which is parallel to the land surface or the horizontal surface. At least three light walls which are vertical to the land surface or the horizontal surface are used for surrounding a space region, or at least three light walls which are vertical to the land surface or the horizontal surface and one light wall which is parallel to the land surface or the horizontal surface are used for surrounding a sealed space (a light house)with the land surface or the horizontal surface. Some targets needing to be monitored are arranged in the light house, and the targets comprise large dams, airports, missile bases or valuables, etc.
Description
Technical field
The present invention relates to a kind of light beam appearance method relevant, particularly relate to a kind of method that forms the light house with monitoring.
Background technology
At present, a kind of method that forms the laser fence is used to monitoring, it is to locate to install infrared laser anti-theft fence device at door or window etc., infrared laser anti-theft fence device is launched 2～8 bundle and even the infrared laser beams of multi beam more, every bundle infrared laser respectively with receive fence on the infrared laser detecting device corresponding one by one, common a branch of infrared laser is corresponding to an infrared laser device.Adjacent two bundle infrared laser interfasciculars have certain distance, are generally 200mm～300mm.But the emission of infrared laser beam along continuous straight runs, the infrared laser fence of formation horizontal direction also can vertically be launched, and forms the infrared laser fence of vertical direction.When people or other object pass the infrared laser fence, just surveyed, so that monitor by the infrared laser detecting device.
Summary of the invention
The object of the present invention is to provide a kind of can being used for to monitor, and close, form the method in the formation light house of different spaces area limiting or enclosure space according to different location, different field boundary.
The present invention forms the method in light house, be the edge that light source sends to be parallel to the light beam that ground or surface level direction propagate be collimated into garden cylindricality parallel beam by collimating apparatus, afterwards, shine on the conical mirror of 90 ° of cone angles more symmetrically, after this conical mirror reflection, form stratiform light beam perpendicular to ground or surface level, this stratiform light beam constitutes the light wall one, utilize at least three roads to become an area of space, form the light house perpendicular to the light circummure of ground or surface level; Or the edge that light source sends is parallel to the light beam that ground or surface level direction propagate is collimated into garden cylindricality parallel beam by collimating apparatus, afterwards, shine on the conical mirror of 90 ° of cone angles more symmetrically, after this conical mirror reflection, formation is perpendicular to the stratiform light beam of ground or surface level, this stratiform light beam constitutes the light wall one, simultaneously, the edge that light source is sent is collimated into garden cylindricality parallel beam perpendicular to the light beam of ground or the propagation of surface level direction by collimating apparatus again, shine the conical mirror of 90 ° of cone angles afterwards more symmetrically, after this conical mirror reflection, form the stratiform light beam that is parallel to ground or surface level, this stratiform light beam constitutes a light wall; Utilize at least three roads to surround an enclosure space zone, formation light house perpendicular to the light wall of ground or surface level and the light wall that is parallel to ground or surface level and ground or surface level.Wherein, the light wall is a stratiform light beam light wall, light source is a lasing light emitter, the length of formed smooth its wall of wall and height are determined by the propagation of light, when clear, be tending towards infinitely great on the numerical value, and the light wall is continuous, every bit on the light wall all has light to exist, the light intensity at certain some place on the light wall, increase apart from the distance of light source with this point and to weaken, the size of the usable reflection conical surface of the beam diameter of the thickness of light wall and incident garden columnated light beam and the conical mirror of 90 ° of cone angles is relevant, as long as 90 ° of satisfied total reflection requirements to symmetrical incident garden cylindricality light beam of conical mirrors, thickness d=the Ф of this time wall/2, Ф is a garden cylindricality beam diameter.The conical mirror of 90 ° of cone angles is positive conical mirror or negative conical mirror, and positive conical mirror is the male conical mirror, generally should plate reflectance coating at the conical surface, to improve the reflection of light rate; Negative mirror is recessed conical mirror, does not need plated film.
Its principle of method that the present invention forms the light house is, the light that light source sends is collimated into garden cylindricality light beam, shines symmetrically on the conical mirror of 90 ° of cone angles, and the direction of propagation of the stratiform light beam through reflecting to form is vertical with the direction of propagation of incident beam.The direction of incident beam is if be parallel to ground or surface level, and then corresponding stratiform light beam is perpendicular to ground or surface level, and promptly the light wall of Xing Chenging is perpendicular to ground or surface level; Otherwise if the direction of incident beam is perpendicular to ground or surface level, and then corresponding stratiform light beam is parallel to ground or surface level, and promptly the light wall of Xing Chenging is parallel to ground or surface level.Utilize perpendicular at least three road light walls of ground or surface level generally speaking and be parallel to ground or one light wall of surface level surrounds a confined space, i.e. light house with ground.Make the stratiform light beam form different angles according to different needs, can form the light house of different shape with ground or surface level.
The advantage that the present invention forms light house method is, closes according to different location or field boundary and can form difform area of space or enclosure space, i.e. the light wall in house, light house, and light can superpose (light beam stack) and not thicken.Utilize the light house that forms to set up exclusion area or no-fly zone to some important goal, placing the target in the light house can be buildingss such as valuables, key departments, machine field boundary, dam.When object strikes light wall, can produce reflection of light or diffuse reflection phenomenon, utilize the Photodetection system that is provided with, receive the reflection or the signal that diffuses, just can obtain the information that object enters the light house, so that take corresponding measure to monitor.
