An Optical Smartphone-Based Inspection Platform for Identification of Diseased Orchids.

Infections of orchids by the or cause orchid disfiguration and are a substantial source of economic loss for orchid farms. Although immunoassays can identify these infections, immunoassays are expensive, time consuming, and labor consuming and limited to sampling-based testing methods. This study proposes a noncontact inspection platform that uses a spectrometer and Android smartphone.
