Wearable visual and non-visual light recorder

Abstract

The invention relates to a wearable visual and non-visual light recorder which comprises a visual sensor and a non-visual sensor. The non-visual sensor comprises a photoelectric detector, a human eyevisual function V (gamma) A correction piece, a human eye visual function V (gamma) B correction piece and dark blue glass which are stacked together; the two sensors are electrically connected with input ends of two portable pre-amplifiers, output ends of the pre-amplifiers are connected with an inside interface of a micropower consumption intelligent box through a probe line, an on-site displayscreen and an on-site button are arranged on the surface of the micropower consumption intelligent box, a single chip microcomputer, a wireless communication module and a power source module are arranged inside the micropower consumption intelligent box, the on-side display screen and the on-site button are electrically connected with an output end of the single chip microcomputer, and the outputend of the single chip microcomputer is connected with a wireless receiving module of a mobile phone side through the wireless communication module. The wearable visual and non-visual light recorder can detect 24-hour light environment of children and analyze proportion of non-visual ingredients and distribution of accumulative exposure along with time.

Description

technical field [0001] The invention relates to the technical field of optical radiation measurement, and in particular discloses a wearable visual and non-visual light recorder for simultaneously measuring the visual and non-visual effects of light. Background technique [0002] For more than 150 years, it has been believed that there are only two traditional photoreceptor cells, cone cells and rod cells, in the retina of the human eye. However, in 2002, David Berson and others from Brown University in the United States discovered a third type of photoreceptor cells in the retina of rats—intrinsically photosensitive retinal ganglion cells—ipRGCs. The photoreceptors control many non-visual biological effects, such as circadian rhythm, body temperature, heart rate, cortisol secretion, melatonin secretion, and alertness, among others. Numerous studies have proved that retinal ganglion photoreceptor cells (ipRGCs) receive light signals through non-visual pathways and transmit ...

AI Technical Summary

Problems solved by technology

As a light measuring instrument probe, the sensor has a wide variety of products on the market, but non-visual sensors are rare, and a detection instrument that simultaneously measures the visual and non-visual effects of light has never been reported in China.
