The invention’s competitive advantage is its portable, handheld, and non-invasive design for internal quality inspection using NIRS-based technology. It improves accuracy and consistency by using a single light source with a small contact area, reducing measurement errors. The integrated sensing system enables real-time, non-destructive assessment, making it practical for fast, on-site use across the supply chain.

Existing internal quality inspection systems often use large contact areas and multiple light sources, which can reduce measurement consistency. There is a need for a device that uses a single light source with a smaller contact area to improve contact efficiency and provide more consistent and reliable quality inspection results.

A portable handheld device for inspecting product quality, comprising a body that houses an illumination system for emitting and receiving light, and an activation mechanism that operates upon contact with the product surface. The system includes integrated sensing elements that measure the amount of light received to assess product quality.

The invention is a portable, handheld, non-invasive device for inspecting the internal quality of fruit. It improves measurement consistency by using a single light source with a small contact area and integrated sensing elements. The system enables simple, real-time, non-destructive quality assessment upon contact with the product surface.
