Kinney & Lange, P.A.
Spectrum detection apparatus
A spectrum detection apparatus is disclosed, including at least one spectrum detection unit. Each spectrum detection unit includes a light source and an optical substrate, including an optical medium layer, the optical medium layer includes a first surface and a second surface opposite to the first surface, and the first surface is closer to the light source than the second surface. The optical substrate further includes a light inlet, a first light-shielding layer, a grating and a light outlet sequentially arranged on the first surface and in an extension direction of the optical medium layer, the first light-shielding layer is configured to reflect target light and absorb non-target light, and the grating is configured to perform diffractive dispersion on the target light. Each spectrum detection unit further includes a micro-fluid substrate and a sensor substrate including a photosensitive sensor configured to detect light from the micro-fluid substrate.
