Objective quality inspection of products in manufacturing process is inseparable from sensor technologies. Inspection methods using analysis of vibration signals have advantages such as being non-destructive, accurate, fast for in-process application. This paper presents recent developments and applications of in-process product inspection which use vibration and acoustic data in various industry. In detail, the inspection system developed with accelerometer, laser vibrometer, laser ultrasonic sensor, acoustic emission sensor, and microphone are presented. An in-process noise detection system for car body parts inspection is introduced as a case study.

Foreign body in food is a matter of concern in food industry as it determines the safety and quality of the product. This issue leads to anxiety as it is hazardous if it is accidentally being consumed. Therefore, foreign body detection is urgently needed. Noninvasive techniques are attractive as they can be used to evaluate without altering the originality of the food products in terms of ingredient and structure. With the growing interest in this subject, this article reviews the development of noninvasive techniques including X‐ray, thermal imaging, near‐infrared spectroscopy, hyperspectral imaging, ultrasonic, and terahertz. The principle and application of each technique are elaborated. The performances and limitations from previous studies in several types of food applications are analyzed. In addition, future trends and challenges encountered with these techniques are highlighted. It is envisaged that the information gathered in this article will be a valuable source of information for researchers working in this topic. Practical applications The existence of foreign bodies in food causes degradation of their quality and safety. The implementation of the noninvasive technique as a monitoring tool have received an encouraging response from the manufacturers which endeavors to maintain their credibility and reputation. This review serves to provide an up‐to‐date development on the noninvasive technique for detecting foreign bodies which is useful for academicians and researchers especially from the food processing industries.

“…The application of low power ultrasound covers the assessment of the composition and physiochemical properties of components. Examples includes food characterization (Benedito, Carcel, Rossello, & Mulet, ; Cho & Irudayaraj, ; Krause, Schöck, Hussein, & Becker, ; Simal, Benedito, Clemente, Femenia, & Rosselló, ), safety (Haeggstrom & Luukkala, ; Ho, Billson, & Hutchins, ; Zhao, Basir, & Mittal, ) and quality control (Aboonajmi et al, ; Kim, Lee, Kim, & Cho, ; Schöck & Becker, ). On the other hand, high power (low frequency) ultrasound is useful for changing the physical and chemical of food properties such as crystallization (Chow, Blindt, Chivers, & Povey, ; Martini, Suzuki, & Hartel, ; Nalajala & Moholkar, ), emulsification (Leong, Wooster, Kentish, & Ashokkumar, ; Mongenot, Charrier, & Chalier, ; Pongsawatmanit, Harnsilawat, & Mcclements, ) and drying (Gallego‐Juárez et al, ; Fernandes, Linhares, & Rodrigues, ).…”

This paper presents the design of an ultrasonic sensor for food quality and safety measurement which is modeled using two dimensions (2D) of finite element method (FEM). The measurement process was implemented by evaluating the presence of foreign body in a food container where the Comsol Multiphysics software was used to construct and conduct the design of modeling. This paper discussed briefly about the applied parameters in ultrasonic measurement which are acoustic impedance, attenuation coefficient, frequency and time of flight. Steel and glass are selected for foreign body's materials since these materials are occasionally present in foodstuffs during the manufacturing process. Some parameters such as frequency of ultrasonic sensor, the thickness of container wall and the size of foreign body were investigated and evaluated. The analysis process is based on the outcome of the total acoustic pressure and the time arrival of the receiving signal. The investigation only considered the ultrasonic transmission sensing mode. Two values of frequencies for ultrasonic sensor are being tested, that is, 45 kHz and 300 kHz. The results showed that the total acoustic pressure is reduced when the thickness of container wall and the size of foreign body are increased. For the 45 kHz frequency, the total acoustic pressures recorded were 1.210 Pa and 1.020 Pa for 0.5 mm and 0.9 mm of wall thickness, respectively. The data is obtained using 5 mm diameter of steel material containing as foreign body. The total acoustic pressure showed the same correlation for a frequency of 300 kHz where 0.658 Pa and 0.420 Pa were obtained for 0.5 mm and 0.9 mm of wall thickness respectively. The results revealed the same correlation for a glass material when it was used as a foreign body. The result shows that the finite elements method is very useful in designing an ultrasonic measurement system in food industry field especially in quality and safety food assessment. Practical applications Food quality is an important aspect for the food manufacturer. It is degraded for example if there is a foreign body in the foods product. It can cause the consumers to lose confidence of the manufacturer. Hence, a suitable sensor should be used to monitor the quality of the products is maintained. Ultrasonic sensors have attracted the attention of the food industry because it is cheap, fast response, and reliable. This paper presents an investigation using the two dimensional finite element method using Comsol Multiphysics software in order to detect the foreign body in a food container using an ultrasonic measurement system. The study demonstrates that the finite element method can assist in the design and development of an ultrasonic measurement system in the food industry field especially in the aspect of food safety and quality assurance.
