Exploitation of non-destructive scanning laser Vibrometry for assessment of firmness and damage in fruit and vegetables (AFM 235) - FT1538

Description
This project aims to demonstrate that laser vibrometry is capable of providing fast, robust and reliable information to implement screening strategies for the assessment of firmness and for damage detection in fruit and vegetables.

Objective
Objective 1: To demonstrate that laser vibrometry is capable of providing fast, robust and reliable information to implement screening strategies for the assessment of firmness and damage detection in fruit and vegetables. The proposed demonstrator system should be capable of operating in industrial environments and delivering significant operational and commercial advantages compared to existing methods. This will provide a business case for Lambda Photometrics to develop bespoke measuring systems specifically for the needs of the consortium partners but also for the food industry in general. It will also provide the end-users (Mack Multiples, M&S and Unilever R&D) with the justification for investing in the proposed technology, with the realistic expectation of recovering the costs of the system through waste reduction, optimisation of processing strategies and consumer satisfaction in relation to quality.

Objective 2: To develop an accurate calibration methodology to determine the excitation, detection and signal processing requirements for the measuring system. This will include assessment of the discrimination capabilities of the system, integrating appropriate physical measurements and statistical techniques to determine the level of sensitivity of the technology and how best to achieve a robust calibration.

Objective 3: To integrate with Objectives 1 and 2 the appropriate type and level of physical and chemometric measurements necessary to establish a firm causal link between excitation input, vibration signatures (resonant frequencies, damping), processed response outputs, taking into account sources of variability (shape, dimensions, ripeness, damage).
