Title:
BIOLOGICAL CHARACTERISTIC DETECTION APPARATUS AND SMART WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/253451
Kind Code:
A1
Abstract:
A biological characteristic detection apparatus and a smart wearable device. The biological characteristic detection apparatus comprises a light-emitting member (101), a light-combining member (102), a light-blocking member (104) and a light-receiving member (103), wherein the light-emitting member (101) comprises two light-emitting units (1011, 1012), the two light-emitting units (1011, 1012) being respectively arranged on different sides of the light-combining member (102), the light emission directions of the two light-emitting units (1011, 1012) both being towards the light-combining member (102), and the irradiation areas, on the light-combining member (102), of a first light beam and a second light beam emitted by the two light-emitting units (1011, 1012) being the same or similar; the light-combining member (102) is used for reflecting the first light beam and transmitting the second light beam, the first light beam and the second light beam being emitted to a user in the same preset direction after same pass through the light-combining member (102); the light-blocking member (104) is used for blocking a light beam emitted by the light-emitting member (101) and a light beam emitted by the light-combining member (102) from being emitted to the light-receiving member (103); and the light-receiving member (103) is used for receiving a first emergent light beam and a second emergent light beam and converting received light signals into electrical signals. Thus, the accuracy of a biological characteristic detection result can be improved.
