The detection of latent traces is an important aspect of crime scene investigation. Blood stains on black backgrounds can be visualized using chemiluminescence, which is invasive and requires a darkened room, or near‐infrared photography, for which investigators need to change filters manually to optimize contrast. We demonstrated the performance of visible reflectance hyperspectral imaging (400–720 nm)...
Background/purposeThis study aimed to develop a method for the assessment of allergic dermatitis by using the long‐wavelength near‐infrared spectrum (more than 1000 nm) to detect intracutaneous allergic type‐specific elements. Such a method was realized by establishing a spectral classifier for the spectra of type I and type IV allergic dermatitis reactions.
MethodsNear‐infrared spectral images of...
