Abstract

Techniques are disclosed for detecting a presence of a biological substance through an article such as a diaper. For example, a detection system causes a light source to transmit light through the article. The light includes a peak wavelength that corresponds to an excitation wavelength of a biological substance that may be present in the article. The detection system detects a measurement of light intensity within a range of emission wavelengths of the biological substance. By comparing the measurement of light intensity to a threshold, the detection system identifies a presence of the biological substance on the article.
