Light field image techniques attract more and more attention due to the ability of achieving digital refocus image and the measurement of depth of field and so on. But, before produce the light field sensor, the cover glass of the sensor would always be removed which result in oxidation and damage of the pixels of the camera. Based on the excellent optical performance of the optic fiber plates, a new design of light field camera was proposed to avoid the oxidation and damage of the pixels. First, remove the cover glass of the sensor, and then optical couple the optic fiber plates above the sensor and install the micro lens array on the optic fiber plates. After the experiment test, the results demonstrate that the established imaging system can provide multiple digital refocus images plane and may play an important role in the three dimensional imaging technology.
