Abstract

Brightﬁeld, darkﬁeld and phase contrast are three of the most popular imaging modalities in biological microscopy. Each provides visualization of diﬀerent sample properties, without ﬂuorescent labels or staining. We demonstrate here a single-camera imaging system that can simultaneously acquire brightﬁeld, darkﬁeld and phase contrast images in real-time. Our method uses a programmable LED array as the illumination source, which provides ﬂexible patterning of illumination angles. We achieve a frame rate of 50 Hz with 2560×2160 pixels of lateral resolution, with speed being limited by the camera.
