AI Technical Summary
In light scanning devices where emission light and external reflection light share the same optical system, internal reflection light can saturate the light receiving element at unintended times, making it difficult to accurately measure the light reception timing of external reflection light.
The control unit executes a process to reduce the electric charges accumulated in the light receiving element during specific periods determined based on the emission timing of the light source, preventing saturation by internal reflection light and allowing accurate measurement of external reflection light timing.
This configuration prevents the light receiving element from being saturated by internal reflection light, enabling accurate detection of external reflection light and enhancing the measurement accuracy of distances to external objects.
