SUBSTANCE FINGERPRINT SPECTRUM SENSING DEVICE AND MEASURING METHOD

Document Type and Number:

WIPO Patent Application WO/2021/134750

Kind Code:

A1

Abstract:

A substance fingerprint spectrum sensing device and measuring method. The sensing device comprises: a supporting frame (10) provided horizontally; a moving unit (20), comprising a translation stage moving member (21) provided on the supporting frame (10) and an acrylic translation stage (22) connected on the translation stage moving member (21) and used for moving in a vertical direction under the driving of the translation stage moving member (21), the acrylic translation stage (22) being provided horizontally; a grating unit (30), placed on the acrylic translation stage (22) and used for carrying a substance; and a prism (40), provided on the supporting frame (10) and directly above the grating unit (30), the grating unit (30) comprising a grating (31) provided with periodic grooves (311) on the surface and a polyethylene filler (32) filling the grooves (311), and the grooves (311) being filled with the polyethylene filler (32) so that the grating unit (30) has a flat surface for carrying the substance. According to the measuring method, the fingerprint spectrum of a substance is measured by a terahertz wave of a terahertz spectroscopy system and the substance fingerprint spectrum sensing device.
