Abstract: The present invention discloses a laser radar for synchronous scanning of line exposure and point lasers of a rolling shutter door and a detection method. The laser radar comprises: a point light source rotating mechanism and an image sensor mechanism; the rotation speed of the point light source rotating mechanism is consistent with the scanning speed of the image sensor mechanism, and the phase is synchronized; and a region illuminated by lasers is in the region corresponding to the exposure line of the rolling shutter door of the image sensor mechanism. The present invention proposes the use of point laser rotating scanning in combination with line scanning of the rolling shutter door to synchronously realize the functions of line lasers.

Abstract: The present invention relates to the technical field of pizza boxes, comprising a box body and a top cover. The box body and the top cover have triangular sector structures. The top end of the box body is open, and the edge of the open end extends outward to form a clamping flange; a lower end surface of the top cover is hermetically abutted against an upper end surface of the clamping flange; the side wall of the top cover is hinged with a plurality of claw buckles along a circumferential direction; the claw buckles have clamping plates and are clamped with the lower end surface of the clamping flange; and the bottom of the box body and the edge of the top cover are wrapped with heat insulation layers. The heat insulation pizza box of the present invention has good sealing and heat insulation effects.
