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.

An ophthalmic apparatus includes an illumination optical system, an imaging optical system, and a controller. The illumination optical system is configured to generate illumination light using light from a light source, and to illuminate a changeable illumination region on a predetermined site of a subject's eye with the illumination light having a light intensity corresponding to a size of the illumination region. The imaging optical system is configured to guide returning light of the illumination light from the subject's eye to a light receiving surface of an image sensor. The controller is configured to control the image sensor to set an opening range so as to overlap an illumination range of the returning light on the light receiving surface corresponding to the illumination region and to capture a light receiving result obtained by a light receiving element in the set opening range.

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.

Examples disclosed herein provide a shutter for obscuring a viewing portion of an opening found on a housing of a computing device. As an example, the housing includes a bezel that includes the opening extending through the bezel. The housing includes a slider deployable from within the housing, and the shutter is to selectively obscure the viewing portion when the slider is to deploy from within the housing.

The system comprises an array of addressable light sources, which is configured for an activation of the light sources individually or in groups, an image sensor comprising pixels, which are configured for the detection of a predefined light pattern, and a rolling shutter of the image sensor. The array of addressable light sources is configured for a consecutive activation of the light sources according to the predefined light pattern or part of the predefined light pattern, and the rolling shutter is configured to expose areas of the image sensor in accordance with the activation of the light sources, so that the pixels in an exposed area are illuminated and the pixels that are outside the exposed area are shielded from illumination.
