The invention provides an optical sensing device, sensing equipment and a system, and relates to the field of sensors. The optical sensing device comprises a light source, a medium containing cavity and a photosensitive element, the medium containing cavity comprises a body and a light-transmitting assembly, the light-transmitting assembly is connected with the body, the body is provided with a medium interface, the medium interface is used for being connected with a sensor, and the sensor injects a light-transmitting medium into the body through the medium interface. The light-transmitting assembly deforms to different degrees according to the injection amount of the light-transmitting medium, and a light signal emitted by the light source is transmitted to the photosensitive element through the light-transmitting medium and the light-transmitting assembly. According to the optical sensing device provided by the invention, the deformation of the light-transmitting assembly is caused by the deformation of the sensor, and the propagation of the optical signal is influenced through the deformation of the light-transmitting assembly, so that the light sensing quantity obtained by the light sensing element is changed, and the purpose of converting the deformation quantity of the sensor into the corresponding optical signal variation quantity is achieved. The optical sensing device has the advantages of strong anti-interference capability, compact structure, stable performance and the like.
