    摘要: An optical probe includes a cylindrical lens adapted to receive and transmit incident light. A light-emitting surface of the cylindrical lens is a curved end surface having a concentric ring-shaped diffractive microstructure. A working position of the optical probe is a position where a diffraction order is 1 when the incident light having a design wavelength between a first wavelength and a second wavelength passes through the diffractive microstructure. When passing through the cylindrical lens, the incident light having the first wavelength produces a diffraction effect with the diffractive microstructure and is converged at a first wavelength working position approximately the same as the working position of the optical probe with the diffraction order of 1. After being refracted by the curved end surface, the incident light having the second wavelength is converged at a second wavelength working position approximately the same as the working position of the optical probe.

    摘要: A measuring method includes the following. An image to be tested of an object to be tested with a first characteristic pattern is formed and is copied to form multiple images to be tested. The multiple images to be tested are superimposed to form a to-be-tested overlapped image which has the multiple first characteristic patterns. A reference image of a reference object with a second characteristic pattern is formed and is copied to form multiple reference images. The multiple reference images are superimposed to form a reference overlapped image which has the multiple second characteristic patterns. The to-be-tested overlapped image and the reference overlapped image are superimposed to generate a virtual moiré image having a moiré pattern different from the multiple first characteristic patterns and the multiple second characteristic patterns.

    摘要: A detection device and a detection method for a malicious HTTP request are provided. The detection method includes: receiving a HTTP request and capturing a parameter from the HTTP request; filtering the HTTP request in response to the parameter not matching a whitelist; encoding each character of the HTTP request to generate an encoded string in response to the HTTP request not being filtered; generating an estimated HTTP request according to the encoded string by using an autoencoder; and determining that the HTTP request is a malicious HTTP request in response to a similarity between the HTTP request and the estimated HTTP request being less than a similarity threshold, and outputting a determined result.

    摘要: A method, a processing device, and a system for information display are provided, and the system includes a light transmissive display. A first information extraction device extracts spatial position information of a user, and a second information extraction device extracts spatial position information of a target object. The processing device performs the following steps. Display position information of virtual information of the target object on the display is determined according to the spatial position information of the user and the spatial position information of the target object. The display position information includes a first display reference position corresponding to a previous time and a second display reference position corresponding to a current time. An actual display position of the virtual information on the display corresponding to the current time is determined according to a distance between the first display reference position and the second display reference position. The virtual information is displayed on the display according to the actual display position.
