A method for controlling access to an entrance may include receiving, via a network from a user terminal associated with a user, identity information and biological information related to the user. The method may also include obtaining a first determination whether the identity information matches the biological information. The method may also include obtaining a second determination whether the identity information has been registered in response to a result that the identity information matches the biological information. The method may also include transmitting the biological information to one or more authorization devices to provide a permission to the user in response to a result that the identity information has been registered. The permission may permit the user to access the entrance by inputting the biological information related to the user through one of the one or more authorization devices.

The present disclosure provides a spectrophotometric colorimeter based on LED light source, wherein the spectrophotometric colorimeter includes an integrating sphere, a coupling light path, and a spectrometer. An inner wall of the integrating sphere is arranged with a composite light source consisting of eight LEDs; a sphere wall of the integrating sphere defines an incident aperture; light emitted from each LED enters an interior of the integrating sphere through the incident aperture and is irradiated onto the inner wall. The coupling light path is configured to couple light at a measurement caliber such that the light can enter an incident split and to eliminate stray light from the inner wall. After emitting out from an observation aperture of the integrating sphere, the light enters the incident split through the coupling light path and is irradiated onto a linear-array sensor after being split by a spectral light path; and different pixels of the linear-array sensor correspond to light radiation strengths at different wavelengths.
