The Vision Group at the Center for Advanced Visual Studies (CAVS) at the Massachusetts Institute of Technology (MIT) has developed the Seeing Machine Camera (SMC) under the direction of Elizabeth Goldring, a visually challenged artist. The SMC is an

A nonlinear state-space dynamic model of a resonating single fiber scanner is developed to understand scan distortion—jump, whirl, amplitude dependent amplitude and phase shifts—and as the basis for controllers to remove those distortions. The no

Image-based holographic stereogram rendering methods for holographic video have the attractive properties of moderate computational cost and correct handling of occlusions and translucent objects. These methods are also subject to the criticism that

A robust hybrid tracking controller for a nonlinear resonating fiber microscanner is developed and implemented to remove scan distortions—toroid and swirl. Using offline batch feedback, a nonlinear search, and simulated regulation, an adaptive cont

We show a new camera based interaction solution where an ordinary camera can detect small optical tags from a relatively large distance. Current optical tags, such as barcodes, must be read within a short range and the codes occupy valuable physical

The novel frequency-multiplexed modulator architecture of the MIT Mark III holo-video display poses a significant challenge in generation of appropriate video signals. Unlike in our previous work, here it is necessary to generate a group of adjacent

We introduce a new holo-video display architecture ("Mark III") developed at the MIT Media Laboratory. The goal of the Mark III project is to reduce the cost and size of a holo-video display, making it into an inexpensive peripheral to a standard des

Recent holographic video research at the MIT Media Laboratory has focused on making a display suitable for consumer use. We discuss our new display architecture, and its novel electro-optical aspects.

Our goal is to produce a micro-optical scanner at the tip of an ultrathin flexible endoscope with an overall diameter of 1 mm. Using a small diameter piezoelectric tube actuator, a cantilevered optical fiber can be driven in mechanical resonance to s
