Disclosed are a laser transceiver device and a laser radar. The laser transceiver device includes a light-splitting coupling unit that splits original light into first original light and second original light, an emerging unit that forms emergent light according to the first original light, and an acquiring unit that acquires echoed light to form signal light, and further includes at least one ofa first acting surface that reflects part of the first original light to form first local oscillating light and a second acting surface that reflects parts of the second original light to form secondlocal oscillating light. Since the first local oscillating light is formed by the first original light partly reflected by the first acting surface and the second local oscillating light is formed bythe second original light partly reflected by the second acting surface, the first local oscillating light and the second local oscillating light have relatively low power, thus the power of the emergent light can be improved effectively, so as to effectively extend the detection distance of the laser radar and expand the detection range of the laser radar while keeping the process and cost unchanged.

The invention discloses a rare earth permanent magnet produced by applying abundant rare earth cerium (Ce) and a preparation method of the rare earth permanent magnet produced by applying abundant rare earth Ce.

The invention discloses a preparing method for an inner embossment card. The preparing method includes the steps that a template with hollow embossment patterns is manufactured; the upper surface of a front face core layer is printed through the template, and the embossment patterns are formed on the upper surface of front face core layer; the front face core layer with the embossment patterns is placed and fixed between a bottom layer and a surface film on the front face, and a card material is obtained; and the card material is pressed to obtain the card with the inner embossment patterns. In the pressing process, the embossment patterns on the upper surface of the front face core layer sink in the direction of the front face core layer under the pressure effect, and a height difference is formed between the embossment patterns and the surface of the blank front face core layer, so that a reflection path of light is changed, and the inner embossment effect is formed. The method is firstly provided, the card prepared from the method is smooth in surface, the inner embossment patterns with the concave-convex view sense are arranged inside, the quality of the card is good, the durability is high, the anti-falsification is high, and the extremely-high application value is achieved.
