Abstract: A measurement system comprises an illumination module, an image pickup device, an angle adjustment module, and a control unit. The illumination module is configured to illuminate an object. The image pickup device is configured to pick up an image of the object. The angle adjustment module is configured to adjust an relative angle between the object and the image pickup device. The control unit is electrically connected to the image pickup device and the angle adjustment module and configured to receive an image signal from the image pickup device. The control unit is configured to command the angle adjustment module to adjust the relative angle to at least three values. The image pickup device is configured to pick up images of the object respectively corresponding to the at least three values. The control unit is configured to calculate the relative angle between the object and the image pickup device.

Abstract: A system, apparatus and method for detecting a porous object are provided. The system includes a light emitting module, a detecting module and an analyzing module. The light emitting module emits light onto an object to be measured such that the light passes through a plurality of holes of the object. The detecting module has a porous plate having a plurality of non-circular holes and a plurality of photosensitive units respectively corresponding to the non-circular holes. Each of the non-circular holes corresponds to at most one of the holes at one time point. The light passes through the plurality of non-circular holes corresponding to the plurality of holes. The photosensitive units respectively sense luminous flux of the light passing through the plurality of non-circular holes to produce a luminous flux signal. The analyzing module analyzes a status of the plurality of holes corresponding to the plurality of non-circular holes.
