Multi-curvature cambered surface reflection target and manufacturing method and experimental method thereof

Abstract

The invention discloses a multi-curvature cambered surface reflection target and a manufacturing method and an experimental method. The manufacturing method of the multi-curvature cambered surface reflection target is used for manufacturing a basin-shaped reflection target, and comprises the steps that: an initial three-dimensional model of the reflection target is set, points of the three-dimensional model are calculated, all the points are connected to form a smooth curved surface, modeling of the three-dimensional model is completed, and the reflection target is processed according to the three-dimensional model. The multi-curvature cambered surface reflection target prepared by the manufacturing method of the multi-curvature cambered surface reflection target has the characteristic of multiple curvatures, can be adapted to convex array probe samples with different curvature radiuses and physical focal lengths, and greatly facilitates the promotion of research and development work.

Description

technical field [0001] The invention relates to the technical field of ultrasonic equipment, in particular to a method for manufacturing a multi-curvature arc surface reflection target. It also relates to a multi-curvature arc reflective target. It also relates to an experimental method for a multi-curvature arc surface reflective target. Background technique [0002] In the field of ultrasonic probe manufacturing, in order to test the prepared convex array probe products or samples, arc reflective targets made of metal are indispensable. [0003] In the test work of the product manufacturing stage, because the probe design has been finalized, it is possible to process a fixed-size arc reflector target that matches the convex array probe product. However, in the process of product development, it is necessary to pre-research many probes with different curvature radii or different physical focal lengths. For the testing of these probe samples, there is no suitable curved re...

AI Technical Summary

Problems solved by technology

However, in the process of product development, it is necessary to pre-research many probes with different curvature radii or different physical focal lengths. For the testing of these probe samples, there is no suitable curved reflector target, which makes it difficult for the test results to reflect the actual situation. Causing distress

For each probe sample with different curvature radii and different physical focal lengths, it is necessary to make an arc-shaped reflective target. On the one hand, it needs to invest money and waiting time. On the other hand, the probe sample may not meet the requirements. It will be discarded directly, so the curved reflector produced in the pre-research stage will cause a waste of time, materials and money
