Video is an effective teaching tool, and live video microscopy is especially helpful in teaching dissection techniques and the anatomy of small neural structures. Digital video equipment is more affordable now and allows easy conversion from older analog video devices. I here describe a simple technique for bringing digital video from one camera to all of the computers in a single room. This te...

An approach that allows superresolution imaging of three-dimensional (3-D) samples by numerical refocusing is presented in the field of digital holographic microscopy. Based on the object's spectrum shift produced by tilted illumination, we present a time multiplexing superresolved approach to overcome the Abbe's diffraction limit. The proposed approach uses a microscope in a Mach-Zehnder inter...

Grottoes are the cultural heritage left by ancient people to modern people, and murals in grottoes can leave a lot of information. In order further improve relevant information meet needs various applications images, this paper studies application digital technology image acquisition system microscope protection art. study, is used collect photos grottoes, then, without compared. At same time, ...

The majority of undergraduate students studying for a science degree will at some point carry out experiments in a laboratory setting, thus developing their practical skills and understanding of experimental principles. For distance learning students, there is no laboratory setting available for them to complete such work and as such there is a risk that they will lack these key skills. The Ope...

We demonstrate a lensfree dual-mode holographic microscope that can image specimens in both transmission and reflection geometries using in-line transmission and off-axis reflection holography, respectively. This field-portable dual-mode holographic microscope has a weight of ~200 g with dimensions of 15 x 5.5 x 5cm, where a laser source is powered by two batteries. Based on digital in-line hol...
