Abstract
We proposed a novel biased optical Kerr gated imaging (BOKGI) method for ultrafast imaging. The imaging performance of the BOKGI system has been investigated. Experimental results showed that by using the BOKGI, the high spatial frequency components of the detected object could be effectively retrieved, which are often filtered by the photo-induced soft aperture in a conventional OKGI system. Comparing with the conventional OKGI method, the BOKGI method could enhance the sharpness of images and provide a higher spatial resolution of the imaging system. In addition, the influence of the biased angle on the BOKGI performance has been also investigated.

Summary
Ultrafast imaging provides an interesting tool applied in fields as diverse as medical imaging, fluid dynamics, and material science. Over the past few decades, the OKGI technique has been used widely for ultrafast fluorescence microscope [6, 7], laser produced plasmas diagnosing [8], three-dimensional shape measurements [9,10,11], time-gated optical projection tomography [12], and imaging of objects hidden in turbid media [13,14,15,16,17]. Placing the Kerr medium on the image plane of the converging lens could avoid the loss of the high spatial frequency components, the object field would be limited by the diameter of the gating laser beam in the image plane [10]. The experimental results show that by using the biased optical Kerr gated imaging (BOKGI), the high spatial frequency components of the detected object could be effectively retrieved, which are often filtered by the photon-induced soft aperture in a conventional OKGI system. Comparing with the conventional OKGI method, the BOKGI method could enhance the sharpness of images and provide a higher spatial resolution of the imaging system
