    摘要: 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.

    摘要: A gray code encoding and decoding method applied to holographic storage devices is proposed. The encoding method uses gray levels of a 2D detector to encode a certain amount of original bits of the original data, and then sends them to a spatial light modulator (SLM) for encryption. The decoding method corrects the received gray levels to the original gray levels, and then compares the maximum gray level with the original gray levels to decode the original gray level into binary data. The proposed encoding and decoding method can better make use of storage locations of the 2D detector and get a code rate close to 1.

    摘要: A waveguide for tympanic thermometer formed by an elongate hollow member having substantially ellipsoidal shape truncated at both ends along its major axis direction. The waveguide is interposed between a tympanic membrane of which the temperature is to be measured and an infrared radiation sensor so as to guide the infrared radiation from the tympanic membrane to the sensor. Alternatively, the waveguide may also be a hollow member including an end portion having a gradually reduced inner diameter toward the side of sensor. The gradually reduced end portion is preferably of a truncated half ellipsoidal shape having a length between about 1/10 to about 1/3 of the distance from the sensor to the distal end of the waveguide.
