However, the uses of ultrasonic pulse-echo scanning technique for composite laminates are dominated by huge company as the costs are high. Therefore, this technique has not yet to reach the desired maturity level for small research and development laboratory scale inspection purpose. Our work is purposely to enhance current problem of an Ultrasonic A-scan prototype with appropriate scanning envelop size, affordable cost with reliability of detect detection result, The mechanism of this machine is achieved by using 3 units of NEMA 17 bipolar stepper motors for the movement of every axis. Arduino microcontroller with help from GUI developed by Visual Studio is used to control the linear- motion s. The technique using a pulse receiver and UT Instrument software is used to acquire A-scan signal form 2.25 MHz transducer before further analyzed by MATLAB. The signal-to-noise ratio (SNR) of the transducer used before and after filter is 29.64 percent and increase to 32.43 percent There solution of transducer used is 1mm. Our scanning speed of this prototype is up to 8mm/s while the scanning envelope size is (400mm x 200 x 100nun). As compared with current products, this prototype is more practical for research and education purpose where some features like type of sensor and scanning path design may chargeable due to experimental needs."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "NDT"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Portable A-Scan measuring unit using 3 Axis Ultrasonic transducer for composite Laminate Material Application.pdf", "filesize": [{"value": "906 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 906000.0, "url": {"url": "https://meral.edu.mm/record/2462/files/Portable A-Scan measuring unit using 3 Axis Ultrasonic transducer for composite Laminate Material Application.pdf"}, "version_id": "0ef30c0b-cd92-4810-9eda-7adb2ed5e4a1"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "8th AUN/SEED-Net Regional Conference on Electrical and Electronics Engineering"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Bakar¸ Elmi Abu"}, {"subitem_authors_fullname": "Mohamed, M.
