Abstract

PURPOSE:To eliminate an error in a laser beam irradiation direction by fixing a target detector to a front part of a laser beam irradiation device in a body, with the optical axis of the target detector made to coincide with the optical axis of the laser beam irradiation device. CONSTITUTION:A target-tracking function of a target detector 4 causes a drive controller 5 to output an instruction signal, which is sent to a main body 1 of a laser beam emitter, thereby directing the optical axis of the target detector 4 toward a target. Since the laser beam emitter and the irradiation target detector are fixed with the optical axes thereof coinciding with each other, directing the optical axis of the rarget detector 4 toward the target causes the optical axis of the laser beam emitter to be also directed toward the target. Therefore, when laser beam is emitted immediately upon detection of the target by the target detector, the laser beam is emitted accurately to irradiate the target therewith.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a laser beam irradiation device for irradiating laser beams to distant places.

[Conventional technology]

Conventionally, in a laser beam irradiation device equipped with a laser beam transmitter and a target detector in order to irradiate a distant irradiation target with a laser beam, the laser beam transmitter and target detector are provided at different positions. was. For this reason, deviations in the optical axes of both optical devices and driving errors are likely to occur, causing errors in the direction of laser beam irradiation.

[Problem to be solved by the invention]

The present invention aims to eliminate the error in the laser beam irradiation direction by creating a structure that does not cause the optical axis shift or drive error.

[Failure to solve the problem]

The present invention has solved the above-mentioned problem, and is a laser beam irradiation device equipped with a laser beam transmitter and a target detector. The present invention relates to a laser beam irradiation device characterized in that it is equipped with a target detector fixed to the front part of a transmitter.

[Effect]

In the present invention, when the optical axis of the target detector is tracked by the laser detector, the laser beam transmitter is also tracking the target at the same time, and when the target detector captures the target, the laser beam The irradiation direction is also correctly directed towards the target. Therefore, no optical axis deviation or drive error occurs.

〔Example〕

FIG. 1 shows a perspective view of an embodiment of the present invention, and FIG. 2 shows a sectional view of the above embodiment. In the figure, 1 is the main body of the laser beam transmitter, 2 is the main reflection value of the concave surface with a through hole in the center, and 3
4 is a support column, 4 is a target detector directed in the same direction as the optical axis of the laser beam transmitter, 5 is 1 drive control device, and 6 is a convex front reflecting mirror. In addition to the above, there is a laser oscillator and a driving device (not shown), which constitute the laser beam irradiation device. The parts shown in FIGS. 1 and 2 are mutually fixed and integrated. The direction indicated by the white arrow in FIG. 2 is the traveling direction of the laser beam.

In this device, a command signal is issued from the drive control device 5 by the target tracking function of the target detector 4. The signal reaches a drive device (not shown) via a control cable installed inside the support column 3, and drives the main body 1 of the laser beam transmitter to direct the optical axis of the target detector 4 toward the target. In this device, the laser beam transmitter and the irradiation target detector are fixed to each other and integrated with their optical axes aligned. Therefore, the target is tracked by the target detector 4,
Pointing the optical axis in the direction of the target means also pointing the optical axis of the laser beam transmitter in the direction of the target, so if the target detector captures the target and immediately sends out the laser beam, The laser beam is irradiated correctly at the target. That is, the error in the laser beam irradiation direction that occurs in conventional devices is eliminated.

In this device, the target detector and drive control device are
These devices are attached to the front of the laser beam transmitter, but since the laser beam is reflected by the front reflection beam, these devices are not affected by the heat of the laser.

〔Effect of the invention〕

In the present invention, the laser beam transmitter and the target detector are integrated with their optical axes aligned with each other, so if the target detector tracks the target and sends out the laser beam when it captures the target, the laser Since the light is correctly irradiated onto the target, errors in the laser beam irradiation direction that occur in the prior art are eliminated.
