A light-emitting device array includes a first light-emitting device, a second light-emitting device, and a third light-emitting device. A first beam shaping structure of the first light-emitting device is configured to convert light emitted by a first light-emitting structure of first light-emitting device into first structured light. A second beam shaping structure of the second light-emitting device is configured to convert light emitted by a second light-emitting structure of second light-emitting device into second structured light. Speckle patterns and spatial distributions of the first structured light and the second structured light on a projection plane are the same. A third beam shaping structure of the third light-emitting device is configured to convert light emitted by a third light-emitting structure of third light-emitting device into third structured light.

A level transducer has a power supply module, a tuning fork module, a sensing-phase corrector and a controller. The tuning fork module has a tuning fork, at least one piezoelectric driving element, and at least one piezoelectric sensing element. The at least one piezoelectric driving element and the at least one piezoelectric sensing element are stacked on each other, and are mounted on the tuning fork. The power supply module is electrically connected and outputs a voltage to the at least one piezoelectric driving element to deform the at least one piezoelectric driving element. The at least one piezoelectric sensing element is extruded and outputs a voltage signal. The sensing-phase corrector obtains the voltage signal and outputs a clock signal to feedback control the voltage on the at least one piezoelectric driving element to optimize a deformation frequency of each piezoelectric element.
