Conventional dispersion compensators were not sufficient to satisfy a demand to set a different dispersion value for each WDM wavelength in a ring-mesh type network that utilizes wavelength selective switches or the like. The devices were insufficiently reduced in size and power consumption and used with difficulty to change dispersion characteristics for each wavelength flexibly in a simple manner. A dispersion compensator of the present invention uses general-purpose optical components including a spatial light modulator for providing discrete phases to set appropriately the relationship between the focusing beam radius and the spatial light modulator pixel, thereby providing various dispersion compensation characteristics. Attention is focused on the correspondence between multiple pixels on the spatial light modulator providing discrete phases and a communication channel band, thereby allowing for changing the flexible dispersion characteristics and realizing the setting of an independent dispersion value for each WDM wavelength.

The disclosure discloses an attention detection method, device, equipment and a storage medium. The method comprises the steps of firstly, acquiring a current video of a user through a camera of clicking and reading equipment, then, decoding the current video so as to obtain corresponding video frames, then, inputting the corresponding video frames to a pre-trained attention detection model so asto obtain an attention number, and finally, determining whether the attention of the user is focused or not according to the attention number and an attention threshold. According to the technical scheme provided by the embodiments, the current video of the user is acquired through the camera, the video is decoded to obtain the video frames, the video frames are input to the attention detection model to obtain the attention number, and whether the attention of the user is focused or not is determined according to the attention number, so that whether the attention of the user is focused or notcan be determined by using the video acquired by the camera, the degree of attention of the user can be reflected objectively, and the problem that the condition that whether the attention of a childis focused or not is determined by parents through observation has subjectivity is avoided.
