Thin plate imaging device

A thin plate imaging device in accordance with the present invention comprises a guide light plate, at least an imaging unit, and at least a photosensitive unit; the guide light plate and the imaging unit are utilized to allow lights to conduct total internal reflective or reflective propagation in a dimension, the photosensitive unit is placed in the path of the total internal reflective or reflective propagation and disposed at the image focus position of the imaging unit; clear images can be obtained without moving the imaging unit or the photosensitive unit back and forth, and objects with different object distances can be imaged on different spots of the photosensitive unit such that relative distances of the objects can be determined by image signals obtained via the photosensitive unit directly.. . ...

Optical touch device using imaging module

An optical touch device using imaging module according the present invention includes a guide light plate, at least a light source, an imaging module, at least a photosensitive unit and a microprocessor; the imaging module has at least an image reflective curved surface to image multiple contact positions to at least a photosensitive unit conveniently to form image information corresponding to the multiple contact positions so as to allow the microprocessor to generate corresponding touch signals; the images at where an object contacts the guide light plate are utilized directly to generate the touch signals instead of detecting attenuation signal of frustrated total internal reflection resulting from the object contacting the guide light plate; due to the light in the guide light plate is employed to conduct the total internal reflection propagation to attain touch control function, components needed in the touch device is reduced and the fabrication cost is saved largely.. . ...
