Abstract: A detector for detecting terahertz electromagnetic radiation comprises a substrate and a pair of electrically isolated detector elements supported thereon. Each detector element comprises a pair of antenna elements having a gap therebetween and a switch element comprising one or more pieces of photoconductive semiconductor material connected between the antenna elements across the gap. The pairs of antenna elements of the respective detector elements are configured so that, when the switch element is conductive, current is generated between the antenna elements by polarisation components of incident terahertz electromagnetic radiation having polarisation directions in respective sensing directions that are perpendicular, thereby providing simultaneous detection of perpendicular polarisation components of incident terahertz electromagnetic radiation.

Abstract: The present application discloses a method for ultrasonic panoramic imaging. Through processes such as coordinate mapping calculation, interpolation, and secondary correction of two images, the to-be-stitched image becomes more accurate, and it is also possible to avoid problems that may arise from noise, tissue movement leading to abnormal images. Furthermore, after a first stitching is completed, the to-be-stitched image is saved as a reference image for use in a next registration. Due to the improved accuracy of the reference image, the continuity and accuracy of subsequent panoramic imaging processes can be ensured.

Abstract: A data providing apparatus obtains first privacy data and second privacy data, encrypts the first privacy data by using an encryption algorithm to obtain a ciphertext of the first privacy data, and sends the ciphertext of the first privacy data and the second privacy data to a data processing apparatus. The data processing apparatus inputs the ciphertext of the first privacy data and the second privacy data into a ciphertext computation function to obtain a ciphertext of a data processing result. In this way, the first privacy data is used in computation in a ciphertext form, thereby ensuring security. In addition, the second privacy data is used in computation in a plaintext form, thereby reducing ciphertext input for the ciphertext computation function.
