Panoptic mechanism cameras

The panoptic camera comprises a main reflecting mirror that reflects light from an entire hemisphere onto an image capture mechanism. The main reflecting mirror consists of a paraboloid shape with a dimple on an apex. The surface area around the dimple allows the main reflector to capture light from behind an image capture mechanism or a second reflector. When two panoptic camera systems that capture the light from an entire hemisphere are placed back to back, a camera system that "sees" light from all directions is created.

PanOpticâ„¢ Ophthalmoscope

The surface area around the dimple allows the main reflector to capture light from behind an image capture mechanism or a second reflector. A stereo vision panoramic camera system is also disclosed. The stereo vision panoramic camera system comprises two panoramic camera systems that are separated by a known distance.

By using the different images generated by the two panoramic camera systems and the known distance between the two panoramic camera systems, the range to objects within the panoramic images can be determined.

Description This application is a continuation of U. In particular the present invention discloses a panoptic camera device that captures virtually all the light that converges on a single point in space.

Thus, a typical conventional camera only captures an image in the direction that the camera is aimed.

Such conventional cameras force viewers to look only at what the camera operator chooses to focus on. However, such panoramic cameras still have a relatively limited field. In many situations, it would be much more desirable to have a camera system that captures light from all directions.

For example, a conventional surveillance camera can be compromised by a perpetrator that approaches the camera from a direction that is not within the viewing angle of the camera. An ideal surveillance camera would capture light from all directions such that the camera would be able to record an image of a person that approaches the camera from any direction.

It would be desirable to have a camera system that would capture the light from all directions such that a full degree panoramic image can be created. A full degree panoramic image would allow the viewer to choose what she would like to look at.

Furthermore, a full degree panoramic image allows multiple viewers to simultaneously view the world from the same point, with each being able to independently choose their viewing direction and field of view.

Other objects feature and advantages of present invention will be apparent from the company drawings and from the following detailed description that follows below. In the following description, for purposes of explanation, specific nomenclature is set forth to provide a thorough understanding of the present invention.

However, it will be apparent to one skilled in the art that these specific details are not required in order to practice the present invention.

For example, the present invention has been described with reference to Ethernet based computer networks. However, the same techniques can easily be applied to other types of computer networks. It should be noted that the camera system is cylindrically symmetrical such that it captures light from a degree band around a point.

The panoramic camera system operates by reflecting all the light from a degree band with a parabolic reflector to a second reflector through a set of lenses , and to an image capture mechanism The set of lenses corrects various optical artifacts created by the parabolic mirror.

The image capture mechanism may be a chemical based film image capture mechanism or an electronic based image capture mechanism such as a CCD. Details on how to construct such a panoramic camera can be found in the U.

As illustrated in FIG. The annular image can later be processed by an optical or electronic image processing system to display the image in a more familiar format.

In one embodiment, the transformation approximates a transform from polar coordinates to rectangular coordinate. Camera System That Collects All Light From A Hemisphere In certain applications, it would be desirable to have a camera system that collects all the light from a full hemisphere around the camera.

For example, a camera system that collects all the light from a full hemisphere could be used by astronomers to capture an image of the entire night sky. Thus, the camera system of FIG. The camera system operates by having a main reflector that reflects light from the entire hemisphere above the camera system to a second reflector The second reflector reflects the light down through a lens system to an image capture mechanism To be able to collect light from a full hemisphere, the main reflector of the camera system consists a cylindrically symmetric mirror with a cross section that consists of an offset parabola.

The offset parabola reflects light from a slightly greater than 90 degree band that starts at the horizon see light ray and continues to the zenith see light rays and and beyond. The short section of parabola near the center of the main reflector allows the main reflector to direct light from the zenith and beyond to the second reflector and down into the image capture mechanism This is illustrated by light ray Although the main reflector of FIG.

This small area in the blind spot can be used to implement a support fixture for the mirror. Alternatively, the small area in the blind spot can be used to implement supplemental lighting.

Camera System That Collects Light From All Directions For some applications, it would be desirable to have a camera system that collects all the light that converges on a point from all directions. Thus, no perpetrator could sneak up on the camera and disable the camera without having his image captured by the camera.The panoptic mechanism is not simply a hinge, a point of exchange between a mechanism of power and a function; it is a way of making power relations function in a function, and of making a function function through these power relations.

The Panopticon is a type of institutional building and a system of control designed by the English philosopher and social theorist Jeremy Bentham in the late 18th century.

Panopticism - Wikipedia

The scheme of the design is to allow all (pan-) inmates of an institution to be observed (-opticon) by a single watchman without the inmates being able to tell whether or not they are being watched.

The PanOptic Ophthalmoscope allows easy entry into the eye, and a 5X larger field of view of the fundus in an undilated eye, providing better images of the retinal changes caused by hypertension, diabetic retinopathy, glaucoma, and papilledema.

The ultimate result is that we now live in the panoptic machine: "We are neither in the amphitheatre, nor on the stage, but in the panoptic machine, invested by its effects of power, which we bring to ourselves since we are part of its mechanism" (Discipline ).

The panoptic mechanism is not simply a hinge, a point of exchange between a mechanism of power and a function; it is a way of making power relations function in a function, and of making a function function through these power relations. Shot in the actual panopticon of a Lisbon psychiatric hospital, the film features a stuffed rhinoceros being slowly, artlessly, and surreally wheeled around the room's perimeter, past the narrow cells.
