摘要： 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 cavity housing the light receiving element. The processor is electrically connected to the light source and controls the light source.

摘要： An embodiment may provide a method for synchronizing a field of view of a distance measuring device including: a light source including one or more light source elements; and a light diffusion device through which light emitted from the light source passes, wherein the light diffusion device is divided into one or more regions, each of the light source elements of the light source is disposed with an independent region, and the intensity of light transferred from the light source elements is adjustable. The method may include: identifying a field of view (FOV) of a red, green, and blue (RGB) camera; and adjusting, based on a predetermined reference, the field of view of the distance measuring device such that the field of view of the distance measuring device corresponds to the field of view of the RGB camera.

摘要： An embodiment provides a beam projector module that includes: a light source configured to output light; a substrate configured to support the light source; an optical device configured to reduce the light in terms of intensity output to a predetermined space; a frame configured to space the optical device apart from the light source by a predetermined distance, the frame forming a closed space with the substrate and the optical device; a temperature sensor configured to measure a temperature of the frame; and a processor configured to control an output of the light source. The processor is configured to operate the light source in an eye-safety mode when a temperature drop rate of the frame exceeds a reference value.
