Embodiment Construction

[0015] Reference will now be made in detail to embodiments of the invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout. The embodiments are described below in order to explain the present invention by referring to the figures.

[0016] figure 1 It is a schematic diagram of the multi-channel laser output structure of the laser light source according to the embodiment of the present invention. refer to figure 1 , the multi-channel laser output structure includes a semiconductor laser light source 1 , an optical fiber 2 , an optical fiber coupler 3 , an optical fiber 4 and a collimator 5 . The semiconductor light source 1 emits laser light, which is transmitted to the fiber coupler 3 through the optical fiber 2. The fiber coupler 3 divides the laser light into four beams, which are independently transmitted from the optical fiber 4 and collimated by the collimator 5, and output as the required ...

Abstract

The invention provides a non-contact six-freedom-degree (DOF) displacement measurement device, which comprises: a stationary part, a light source luminous part which comprises a four-way laser output structure that is fixed with the stationary part together and emits beams, and a photoelectric receiving part which is fixed with an object to be measured together and comprises four area-array CCDs,wherein, each CCD respectively receives an one-way light source signal among the light source signals emitted by the four-way laser output structure; when the object to be measured carries out movement of arbitrary DOF, the position of a corresponding light point on the CCD is caused to be changed, and the six-DOF displacement of the object is calculated according to the light point position before and after the change. The non-contact six-DOF displacement measurement device can be used for the high-precision six-DOF micrometric displacement monitoring of objects.

Description

technical field [0001] The invention relates to a non-contact six-degree-of-freedom displacement measuring device, which belongs to the field of photoelectric measurement, and is particularly suitable for high-precision measurement of relative micro-displacement of six degrees of freedom between objects. Background technique [0002] The movement of any object in space has 6 degrees of freedom, that is, translation in 3 directions (Δx, Δy, Δz) and rotation around 3 directional axes (θ x , θ y , θ z ). The development of modern science and technology has put forward higher requirements for machining accuracy, installation accuracy and detection accuracy in many fields such as aerospace, aviation, machinery, and instrumentation. The positioning of the processed workpiece, the installation of precision parts, the position and motion monitoring of the target object in space, etc., all require measurement, adjustment and control of up to 6 degrees of freedom. Due to its broad...
