The invention relates to a method and device for observing photoacoustic imaging in a single-array element and multi-angle mode based on compressive sensing, belonging to the technical field of photoacoustic imaging and aiming at solving the problems of serious artefact, deformed images, high hardware cost and poor lateral resolution of images in the existing photoacoustic technology for imaging biological tissues. The method comprises the following steps: leading a pulsed laser to emit pulsed laser beams, irradiating the pulsed laser beams upon the biological tissues by using an optical mask to generate photoacoustic signals, observing and acquiring the photoacoustic signals synchronously by using two angled single array element ultrasonic probes, amplifying the photoacoustic signals, sending the photoacoustic signals to an A / D (analog to digital) converter, sampling uniformly, inputting acquired photoacoustic image data into a computer by using an FPGA (field programmable gate array), and reconstructing and fusing photoacoustic images by using the computer. Due to the adoption of a hardware platform and a processing mechanism which is rapidly constructed based on the compressive sensing algorithm by using the single array element ultrasonic probes to acquire the photoacoustic signals in parallel, the high resolution of the images are ensured on the premise that the sampled data are reduced and the acquiring time is shortened. The device for imaging is easy to operate.

The invention provides a live broadcast system based on automatic control that can instantly obtain high-definition photos, including a host computer, a slave computer, a server, and a user terminal; the host computer includes a movable bearing device, which is equipped with The cloud platform, the image acquisition device connected with the platform and the first transmission module; the image acquisition device includes one or more camera modules.
