==LIGHT-PROJECTION DEVICE AND RANGE FINDING APPARATUS THAT USES LIGHT-PROJECTION UNIT - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18492647 titled 'LIGHT-PROJECTION DEVICE AND RANGE FINDING APPARATUS THAT USES LIGHT-PROJECTION UNIT

==Simplified Explanation==

The patent application describes a light-projection device used for range finding by measuring the time difference between emitting light and detecting reflected light.

* Light-projection device includes a light source array with multiple light-emitting elements arranged in two dimensions.
* Device also includes a light-projection lens to adjust the light projection range.
* A driving device changes the relative positions between the light source array and the light-projection lens.
* A light source control unit switches on the light source array when in different positions.

### Potential Applications
* Distance measurement in surveying and mapping
* Object detection in robotics and automation
* 3D scanning and imaging technologies

### Problems Solved
* Accurate distance measurement without physical contact
* Improved precision in range finding applications
* Enhanced efficiency in object detection processes

### Benefits
* Increased accuracy in distance measurement
* Versatile applications in various industries
* Enhanced automation and efficiency in processes


==Original Abstract Submitted==

Disclosed is a light-projection device that is used for a range finding apparatus that computes a distance to an object that has reflected light, by measuring a time difference between a time when light is emitted and a time when reflected light is detected. The light-projection device comprises a light source array in which a plurality of light-emitting elements are two-dimensionally arranged and a light-projection lens that adjusts a light projection range of light emitted from the light source array. The light projection device further comprises a driving device that changes relative positions between the light source array and the light-projection lens and a light source control unit that switches on the light source array under conditions where the light source array is in different positions.
