▼a Computer vision technology coupled with uniform illumination is still unsatisfactory in detecting some defects of apples, e.g., subsurface tissue bruising. Structured illumination (SI) provides an alternative illumination scheme, which is advant |

▼a A SIRI platform, capable of acquiring broadband and multispectral images, was constructed by using a digital micro-mirror device based digital light projector. Using sinusoidally-modulated illumination patterns, SIRI acquires phase-shifted patte |

▼a Demodulation is a critical step in obtaining DC and AC images, and conventional approaches require a minimum of three phase-shifted pattern images. New demodulation approaches based on spiral phase transform (SPT) and Gram-Schmidt orthonormaliza |

▼a Experiments were conducted on detection of subsurface bruising in apples of four varieties by using a multispectral SIRI system, in conjunction with the SPT demodulation approach. The six wavebands between 710 and 810 nm yielded the overall dete |

▼a This research has demonstrated the feasibility and potential of SIRI as a new versatile and effective tool for enhancing defect detection of apples. More research, however, is needed to improve the instrumentation and software of SIRI for real-t |
