The invention relates to the field of precision measurement technology and the field of optical engineering and in particular relates to a portable combined zero setting high precision laser large working distance auto-collimation device and method. The device comprises a light source, a collimating mirror, a reflector, and a feedback imaging system. The method makes reflected light beams return to the image plane center of the feedback imaging system by adjusting the reflector and obtains the angle change of the surface of a measured object by means of an angle deflection measuring device on the reflector.

The invention belongs to the fields of precise measurement and optical engineering, and specifically relates to a portable combined zero-setting laser large-working-distance auto-collimation device and method. The device consists of a light source, a collimating mirror, a reflector, and a feedback imaging system. The method comprises the steps: enabling a reflected light beam to return to the center of the imaging plane of the feedback imaging system through adjusting the reflector, and obtaining the angle change of the surface of a measured object through employing an angle deflection measurement device on the reflector. According to the invention, the reflector is added to a conventional auto-collimation angle measurement system, so the device can solve a problem that the reflected light of the measured object cannot be measured because the reflected light deflects from the measurement system, enlarges the auto-collimation working range under the condition of the same working distance or increases the working distance under the condition of the same auto-collimation working range. In addition, the specific design of the collimating mirror, the feedback imaging system and the reflector enables the device to be small and portable, and to be high in measurement precision. The device still can carry out measurement in an unstable measurement environment, and can achieve quick measurement.

The device is composed of a light source, a collimating mirror, a reflector and a feedback imaging system, and the method is characterized in that by adjusting the reflector, a reflected light beam returns to the center of an image plane of the feedback imaging system, and then by utilizing an angle deflection measurement device on the reflector, the angle change on the surface of a measured object is obtained. According to the present invention, by adding the reflector on a conventional auto-collimation angle measurement system, the problem that the reflected light of the measured object deviates the measurement system, so that the reflected light of the measured object can not be measured, can be avoided, and further the technical advantage that an auto-collimation working range is increased under a same working distance, or the working distance is increased under the same auto-collimation working range, is realized.

The invention belongs to the technical field of precision measurement and the field of optical engineering and specifically relates to a high precision, wide range and large working distance laser auto-collimation device and method. The device consists of a light source, a collimating mirror, a reflecting mirror and a feedback imaging system; according to the method, via adjustment of the reflecting mirror, a reflected light beam is enabled to return to a center of an image plane of the feedback imaging system; an angular deflection measurement device on the reflecting mirror is used for obtaining angular variation of a surface of an object being tested.
