Example Embodiment
[0022] Example 1: Such as figure 1 As shown, the feedback laser energy wireless transmission device of the present invention includes a transmitting component at the transmitting end and a receiving component at the receiving end. The transmitting component includes a semiconductor laser and a beam expander. The receiving component includes a photocell array. The transmitting assembly also includes a tracking and aiming system for tracking and aiming at the receiving end, and the receiving assembly also includes a corner reflector array arranged in front of the photocell array for reflecting a part of the laser beam from the transmitting assembly back to provide the semiconductor laser with positive With feedback, another part of the laser beam is transmitted to the photovoltaic array. The laser beam is converted into electric energy storage through the photovoltaic cell array, realizing the wireless transmission of energy. The transmitting end and the receiving end are separat...
Example Embodiment
[0026] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the emitting assembly includes multiple laser gain media. The tracking and aiming system includes: tracking and aiming a 45° total reflection mirror at the receiving end by adjusting the incident angle of the laser light emitted by the transmitting end. The beam expander includes a coaxial concave lens and a convex lens. Such as figure 2 As shown, the total reflection mirror M3, the concave lens M4 and the convex lens M5 constitute a two-dimensional turntable T, figure 2 The dashed box in the middle represents the two-dimensional turntable T. The 45° total reflection mirror M3, concave lens M4 and convex lens M5 are fixed on the two-dimensional turntable T and can rotate around the X axis and Y axis of the center of the 45° total reflection mirror (⊙ means that the Y axis direction is from the inside of the paper to the outside of the paper ), in order to realize the two-dimensional scanning...
Example Embodiment
[0028] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the corner reflector array is a hemispherical corner reflector array composed of corner reflectors. The transmitting end includes a plurality of transmitting components. Such as image 3 As shown, the transmitting end includes multiple transmitting components S1, S2, S3...; the receiving end includes one receiving component. The corner reflector array M2 in the receiving assembly adopts a hemispherical corner reflector array composed of multiple pyramid corner reflectors. Due to the directional reflection characteristics of the corner reflector array M2, the corner reflector array M2 can form a plurality of laser oscillators with a plurality of emitting components S1, S2, S3... The photovoltaic cell array PC located behind the hemispherical corner reflector M2 is also arranged in a hemispherical shape or directly fixed on the outer side of the quadrangular pyramid corner reflector to complete...
