There is provided an optical engine for a navigation device including a first light source, a second light source, a lens, a carrier member and an image sensor. The carrier member has a light holder, a lens holder, an accommodation space and a tilted wall. The first light source is arranged on the light holder of the carrier member, and reflected light associated with the first light source penetrates through the lens to propagate to the image sensor inside the accommodation space. Reflected light associated with the second light source penetrates through the tilted wall of the carrier member to propagate to the image sensor.

Optical engine with multiple light sources and package structure thereof

A tracking device including an image sensor, a light source and a processor is provided. The image sensor senses reflected light or scattered light formed by the light source illuminating a work surface. The processor calculates a trace of the tracking device according to one of the reflected light and the scattered light that generates more apparent image features so as to increase the adaptable work surfaces.

Tracking device and electronic device having two image sensors

There is provided a mobile robot that performs the obstacle avoidance and visual simultaneous localization and mapping (VSLAM) according to image frames captured by the same optical sensor. The mobile robot includes a pixel array and a processor. An upper part of the pixel array is not coated with any filter and a lower part of the pixel array is coated with an IR filter. The processor performs range estimation using pixel data corresponding to the lower part of the pixel array, and perform the VSLAM using pixel data corresponding to the upper part of the pixel array.

Mobile robot performing multiple detections using different parts of pixel array

There is provided an electronic product that performs the obstacle avoidance, positioning and object recognition according to image frames captured by the same optical sensor. The electronic product includes an optical sensor, a light emitting diode, a laser diode and a processor. The processor identifies an obstacle and a distance thereof according to image frames captured by the optical sensor when the laser diode is emitting light. The processor further performs the positioning and object recognition according to image frames captured by the optical sensor when the light emitting diode is emitting light.

Electronic product performing multiple detections using image frames of same optical sensor

There is provided a lens including a first curved surface and a second curved surface. The first curved surface and the second curved surface have different focal distances and are arranged interlacedly along a radial direction of the lens.

Multifocal lens

Electronic device with light sources emitting in different directions

There is provided a bottom cover for being covered on an optical system. The bottom cover is attached in front of the optical engine. The bottom cover has a bottom surface for facing a working surface when the optical system is moving on the working surface, a first opening for emission light of the optical engine to go through and a second opening for reflected light from the working surface to go through. The bottom cover is further formed with guiding protrusions protruded out from the bottom surface toward the working surface and surrounding at least the second opening to guide soft materials on the working surface to away from the second opening.
