A gray level weighting centroid method for holographic data storage is disclosed. Firstly, a first gray level image having a plurality of blocks is received. Then, a convolution calculation is performed on a weight matrix and the image, so as to obtain a second gray level image having a plurality of blocks each having a gray level value. The gray level values are divided into a bright gray level value and a dark gray level value by a threshold value, so as to convert the second gray level image into a thresholding image and find the positions of the borders of the blocks corresponding to the bright gray level value. Next, the blocks surrounded by the positions of the borders and respectively used as a centroid block are found by making the positions of the borders correspond to the first gray level image. Finally, the centroid block is calculated to obtain a centroid point.

The present invention discloses a portable noninvasive inspection device, which comprises a light source illuminates an target to generate an optical inspection signal; a probe head provides an optical path for said light source to receive said optical inspection signal; at least one switched filter module arranged in the optical path, allowing the optical inspection signal to pass therethrough to generate a corresponding spectral signal; and an image sensor arranged behind the switched filter module, receiving the spectral signal and generating a spectral image. The spectral image can be transmitted to an external device, wherefrom the user can use the spectral image to examine the target in further detail. The present invention features a rotary-type or movable-type switched filter module, which facilitates the user to switch filters easily during optical inspection and expands the application of the present invention.

The present invention discloses a portable pupil detection device with multiband stimulating light and infrared illumination, which comprises at least one pupil detection module for detecting the variation of the pupil of the testee. Each pupil detection module includes an illuminating light source emitting invisible light beams; a stimulating light source emitting visible light beams; at least one beamsplitter corresponding to the illuminating light source, the stimulating light source and an eye of the testee, cooperating with the illuminating light source and the eye to form a first optical path, and cooperating with the stimulating light source and the eye to form a second optical path; a lens corresponding to the beamsplitter and receiving the invisible light beams sent out by the beamsplitter to form an image of the eye; and an imaging element receiving the image of the eye from the lens.
