摘要

Lensless or lensfree microscopy is now available commercially. With these new microscopes, it is possible to record images in contact mode with a magnification of 1 or in holographic mode with a magnification larger than 1. In this Letter, we present an original setup that allows us to record the image of an object whose surface is larger than that of the image sensor without placing an optical component between the object and the image sensor.
