Abstract
The utility model relates to a laser for emitting subparallel diverging light. A compensation light source adopted by an existing system is a traditional scattered or reflective luminous light source. When the traditional scattered or reflective luminous light source is adopted, the emitted light is divergent, and the energy loss of the light intensity when the light is emitted to the surface of an object to be shot is greater, so that the exposure requirement of a linear camera can not be met. The laser provided by the utility model comprises a shell (1), wherein a rotating body (2) is sleeved in the shell, one end of the rotating body is connected with a planoconvex spotlight (4), the other end of the rotating body is connected with a prism (5), the shell is connected with a focusing component which is connected with a fiber-optical splice (7), and the fiber-optical splice is connected with a semiconductor laser (8). The product is used for auxiliary facilities when the linear scanning camera is shooting.
Description
Technical field:
The utility model relates to a kind ofly can take laser high brightness is provided, send out uniformly parallel diverging light near for the linear array scanning camera.
Background technology:
In order to ensure the railway freight-car traffic safety, railway system's system-wide has been applied TFDS (TFDS).In order to improve the performance of TFDS, adopt the shooting of high-speed industrial linear array scanning camera need detect the position in the system and take lorry, by browsing computer the body portions bitmap sheet of taking is carried out fault detect by station inspector again.
The compensatory light that existing system adopted is the conventional light source of scattering or reflection type light-emitting.When adopting the conventional light source of scattering or reflection type light-emitting, that sends only disperses ejaculation, when light is very big to the surperficial light intensity energy loss of the target that is taken, can't satisfy the demand that line-scan digital camera exposes.
Summary of the invention:
The purpose of this utility model is that the problem at above-mentioned existence provides a kind of laser of sending out parallel diverging light near, the not enough problem of TFDS system captured car bottom parts image brightness in the time of can effectively solving the conventional light source that adopts scattering or reflection type light-emitting.
Above-mentioned purpose is achieved through the following technical solutions:
The laser of sending out parallel diverging light near, its composition comprises: housing, described housing the inside suit rotary body, one end of described rotary body connects planoconvex spotlight, the other end of described rotary body connects prism, described housing connects focusing component, and described focusing component connects optical fiber splice, and described optical fiber splice connects semiconductor laser.
The described laser of sending out parallel diverging light near, described focusing component comprises the focusing handle that is connected with described housing, described focusing handle connects focusing drum, described rotary body the inside suit nylon back-up ring, described prism bottom connects sealing gland.
The described laser of sending out parallel diverging light near, described planoconvex spotlight bottom has the planoconvex spotlight seat, connects the planoconvex spotlight gland above the described planoconvex spotlight.
Beneficial effect:
1. the utility model enters optical lens system by optical fiber splice by the one-wavelength laser light beam that semiconductor laser sends after Optical Fiber Transmission, this laser beam enters the focusing component of being made up of convex lens, focusing cylindrical shell, adjusts the focusing cylindrical shell and the focus of laser beam can be adjusted on the focus of convex lens.The laser beam that passes convex lens is resolved into the fan beam at 60 degree angles again by prism 6.Spatial distribution through the light source after the above optical system conversion is a parallel fan-shaped light source, is transmitted into the target surface that is taken that need take, to realize high high brightness, the evenly illumination to the target surface that is taken.
2. when adopting the infrared laser line source, can also effectively solve the light interference of conventional light source to the driver, and because the laser linearity light-source brightness height of sending out near parallel diverging light, can reduce the time for exposure the clear shooting problem when cooperating filter to eliminate the sunlight direct projection effectively again under the backlight condition.Laser line light source realizes that for the high-speed industrial linear array scanning camera in the TFDS system operation lorry is carried out clear shooting provides a kind of very desirable light source under various ambient lighting conditions.
