Table 2 Samples created to validate the proposed technique and the wavelengths at which they were sequentially illuminated using OS1 to generate PAM images and subsequently map the chromophores.

|---|---|---|---|
Melanin | Human hair | 550 | 650 |
Hemoglobin | Water and dry hemoglobin (150 g/l) | 550 | 650 |
Gelatine | Water and gelatine (150 g/l) | 1200 | 1700 |
Glucose | Water and glucose (150 g/l) | 1600 | 1700 |
Lipids | Water and chicken adipose fat | 1200 | 1600 |
