WebSince the width of the reflection area in the detection image is determined by the width of the light source module and the light aperture of the lens module, by setting a slit on the incident light path of the lens module or on the surface of the lens module, the reflection area and A clearer boundary line is formed between non-reflective ... WebReal images are formed when light rays after reflection or refraction converge at a point before a mirror or lens. While virtual images are formed when the light rays diverge after reflection or refraction.
