AI Technical Summary

Problems solved by technology

However, there are problems with data loss, increased impedance, and increased power consumption due to the physical distance between the laser diode driver and the light source, and this makes accurate data transfer between the light source and the laser diode driver difficult

Embodiment Construction

[0045] Hereinafter, some embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In each drawing, when a reference numeral is added to each element, the same element will be denoted by the same reference numeral as much as possible, although the same element will be shown in different drawings. Also, in the following description of the present disclosure, when it is determined that the description may make the subject matter of the present disclosure unclear, a detailed description of known functions and configurations introduced herein will be omitted.

[0046]Also, when describing components of the present disclosure, terms such as first, second, A, B, (a), (b) may be used herein. These terms are used only to distinguish one structural element from other structural elements, and the nature, sequence, sequence, etc. of the corresponding structural elements are not limited by the terms. When it is stated in the specificat...

Abstract

A distance measuring apparatus has a substrate supporting, on a first surface thereof, a light source that emits light and a first optical element that decreases the intensity of the emitted light, and a processor on a second surface opposite the first surface. A light receiving element and a second optical element, which is at a higher position than the light receiving element, both receive the emitted light after reflecting from an object. A frame is connected to the substrate and spaces the first optical element and the second optical element a predetermined distance apart from the light source and the light receiving element, and a partition is disposed between the light source and the light receiving element, thereby defining a first cavity housing the light source and a second cavityhousing the light receiving element. The processor is electrically connected to the light source and controls the light source.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2019-0025674 filed on March 6, 2019, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] The present disclosure relates to a ranging device. Background technique [0004] Lasers are derived from the acronym "light amplification by stimulated emission of radiation" and are capable of emitting light with high coherence. Moreover, lasers can emit directional monochromatic light, which allows lasers to be used in various fields of optical sensor technology. [0005] For example, lasers can be used as light sources for distance measuring devices as well as for 3D depth cameras. A time-of-flight (ToF) type distance measuring device calculates the time of flight between a light source and an object based on a phase difference between pulsed light output from a light source and this pulsed ligh...
