  • Patent number: 11953312
    Abstract: The invention includes a system and method for obtaining high-resolution 3D images of objects. The system includes three cameras and three light sources that have different wavelengths (e.g. a red light source, a blue light source and a green light source). Each camera simultaneously captures a color image of the object. A processor separates each of the red light images, the blue light images and the green light images into separate monochrome images using each of the red light source, blue light source and green light source. The quality of the images are not subject to limited resolution of conventional RBG images. Because three different wavelengths of light are used, the surface can be accurately imaged, regardless of its characteristics (e.g. reflectivity and transparency). The system is well suited for industrial uses that require a high volume of objects, particularly those of mixed material, to be rapidly inspected for defects as small as a few microns.

The bandgap reference circuit includes a startup component; an output component; and a bandgap core component coupled there-between. The bandgap core component includes a reference point having a voltage associated with an output signal of the output component. A controller is configured for controlling the bandgap core component and the output component to switch between a low power consumption mode and a normal operation mode based on the voltage at the reference point. When the bandgap core component and the output component operate in the normal operation mode, the bandgap reference circuit outputs a stable voltage and has a first power consumption. When the bandgap core component and the output component operate in the low power consumption mode, the bandgap reference circuit has a second power consumption less than the first power consumption.
