Abstract: An image processing unit for optical tomography is applicable in miniaturized diffusion optical tomography devices. It includes an image reconstructor and an image post-processor. The image reconstructor receives a plurality of optical signals generated from an reaction of an object under test with irradiating light and an inverse solution matrix of an image model of the object, and obtains scalar product on each of the optical signals and the inverse solution matrix through a sub-frame algorithm to generate an original image corresponding to the object. Then, the image post-processor performs a Gaussian extended algorithm on the original image to output a final image. With the image reconstruction and image post-processing of the present invention, slowing down of computation speed due to miniaturization of the conventional optical tomography techniques can be avoided, while providing good quality in the output image.

Abstract: A conveying device includes a multiplexing control device and power wheels, and the multiplexing control device includes sensors, a bus, a first controller and a second controller. The sensors are used to receive travelling information and output sensing signals. The bus is used to receive the sensing signals and output the sensing signals to the first controller and the second controller. When the conveying device operates, the first controller controls the power wheels according to the sensing signals. If the sensing signals are too complicated, the second controller performs processing together with the first controller. If the first controller is damaged, the second controller replaces the first controller and controls the power wheels according to the sensing signals.
