为了获得较大场景的全息照片,采用了多组同类廉价激光器同时照射被摄物和全息干板,单次记录或多重记录全息图的方法。克服了由于受到激光器功率和激光光源相干长度的制约而引起的高的拍摄费用。经过实验,能获得拍摄场景达125°、清晰的全息照片。

In order to obtain large scene holographic photos, methods of adopting multiple groups of cheap lasers with same types to irradiate the objects photographed and holographic dry plate at the same time, single record and multiplexed records of hologram are used. It overcomes high cost photographing because of the constraints of coherent lenghs of laser power and laser sources. By the experiments, clear holographic photos of which photographing scene is 125° are achieved.
