Our new paper on fluorescent DIC comes out!

A new speckle pattern fabrication method is proposed in this paper, by using an off-the-shelf handheld inkjet printer. By printing, the speckle pattern quality will no longer depend heavily on the operator. A good quality control is achieved. This method can be used for both fluorescent and classic speckles preparation. The former, published on APL 2020, has distinguish advantages and we highly recommend for general use.
