Laser self-mixing interference type infantile child pupil light reflex meter

Abstract

The invention discloses a laser self-mixing interference type infantile child pupil light reflex meter which comprises a left eye image sensor, a right eye image sensor, a data acquisition card and eyeballs, the left eye image sensor comprises a semiconductor laser, the right eye image sensor is installed at the left end of a glasses support, and the left eye image sensor is installed at the right end of the glasses support. The right eye image sensor and the left eye image sensor are symmetrically distributed about the center of the glasses support, the data acquisition card is installed on the glasses support, the data acquisition card is connected with the computer, and the semiconductor laser is sequentially provided with light spot size regulators along the light path of the semiconductor laser. According to the laser self-mixing interference-based autistic child pupil light reflectometer, a brand-new laser self-mixing interference-based pupil image sensor is constructed, and a laser self-mixing interference-based pupil image sensing processing method is combined, so that a novel laser self-mixing interference-based autistic child pupil light reflectometer is designed; the laser self-mixing interference type infantile child pupil light reflex meter is used for pupil light reflex measurement of autistic children.

Description

technical field [0001] The invention relates to the related technical field of precision optical interferometry, in particular to a pupil light reflectometer for autistic children with laser self-mixing interference. Background technique [0002] Autism spectrum disorder (Autism Spectrum Disorder, ASD) is a kind of neurodevelopmental disorder in children characterized by social interaction and communication impairment, narrow interests and stereotyped behavior. Clearly, coupled with the serious shortage of diagnosis and intervention resources, autism has evolved into a major global public health problem. "Early detection, early intervention and long-term rehabilitation training" are currently the most effective treatment methods. Unfortunately, although early signs may Appeared at the age of 12 months, most children are not diagnosed with ASD until they are 4 years old, because the screening and diagnosis of ASD patients are still limited to relying on doctors to conduct sca...
