Filed:

Jun 7, 1982

Appl. No.:

6/385465

Inventors:

Joseph A. LaRussa - Yorktown Heights NY

Assignee:

Farrand Optical Co., Inc. - Valhalla NY

International Classification:

H04N 718

US Classification:

358101

Abstract:

A robotic system for grasping a randomly oriented object, comprising grasping means for grasping said object is disclosed. Motor means places the grasping means at a desired position and causes performance of a gripping function. Camera means forms a first image of the object. An optical train conveys an image from a predetermined point to the camera means, the predetermined point being fixed relative to the grasping means. Image means contains a second image of the object to be grasped. Comparison means compares the first image to the second image. First coupling means couples the image means to the comparison means. Second coupling means couples the output of the camera means to the comparison means. Image rotation means causes rotation of the second image with respect to the image produced by the camera means. The comparison means is responsive to the first and second coupling means to stop rotation of the image rotation means when a coincidence in angular position is detected between the second image and the image produced by the camera means.

Assignee:

Farrand Optical Co., Inc. - Valhalla NY

International Classification:

G02B 2714

US Classification:

350174

Abstract:

An optical simulation system comprising a model (12) and collimating optics (16) is disclosed. An image is presented to an observer (32) by means of a plurality of lenses (24, 26) and mirrors optically aligned with the collimating optics. The optics of the system are adjustable so that the range changes of the model can be accommodated without moving large optical elements.

International Classification:

G02B 2710
G02B 532

US Classification:

359 13

Abstract:

A holographic display system is disclosed. Utilization of holographic elements provides good transmissivity with respect to both outside stimulus and the superimposed display information. Full color display is enabled by a composite spherical lens and the efficient optical coupling of the display information and the pupil allows the weight of the helmet with the display system to be kept to a minimum.

Appl. No.:

9/170477

Inventors:

Joseph Larussa - Yorktown NY

International Classification:

G02B 2714

US Classification:

359630

Abstract:

A visual display system having a plurality of optical systems, defining a viewing area whereby an observer views a continuous field of view in both the horizontal and vertical directions. Each of the optical systems collimate light from an image source to provide an image at infinity focus and an second image which is not focused at infinity whereby the image not focused at infinity increases or decreases in size as the observer moves within the defined viewing area.

Appl. No.:

Farrand Optical Co., Inc. - Valhalla NY

International Classification:

G09B 900

US Classification:

434 22

Abstract:

A target designation system for use in training an observer to acquire and recognize targets is disclosed. A scenario with targets is displayed in front of the observer who aligns his line of sight so that a reticle is superimposed on the acquired target. The display system consists of film illuminated by a cathode ray tube. Film is used to provide color, resolution and realism not available from cathode ray tubes or any other display system. Light rays from the display are partially transmitted through a beam-splitter to the observer and partially reflected through an optical window onto a photodetector. In addition, the projected image of the reticle is reflected by the beam-splitter toward the observer. The photodetector and optical window are positioned so that light rays from the scanning spot of the CRT raster impinge on the photodetector only when the scanning spot occupies a point on the CRT screen corresponding to the location on the film at which the image of the reticle is superimposed. When the observer closes a switch, the photodetector outputs on electrical pulse to the deflection yoke circuitry in response to receipt of light rays from the scanning spot.

Inventors:

Joseph A. LaRussa - Yorktown Heights NY

Assignee:

Farrand Optical Co., Inc. - Valhalla NY

International Classification:

G09B 902

US Classification:

434 43

Abstract:

An apparatus (10) simulates scenic translation and comprises simulator controls (64) which generate signals (18-26) corresponding to the horizontal position of a vehicle. Video storage unit (12) generates a raster (54) including video information (58) representing a scene to be viewed. A microprocessor (65) responsive to the simulator controls generates control signals for selecting a portion (50 or 52) of said raster corresponding to the position of the vehicle. Horizontal and vertical delay gates (112,114) responsive to the microprocessor select a portion of each line in said raster. A video monitor displays the selected portions.

International Classification:

US Classification:

340980

Abstract:

A system for presenting a head-up display to the operator of a vehicle is disclosed. This system comprises a light source fiber optic bundle (52) which is secured to the helmet of the vehicle operator and generates a light beam signal which travels at an angle proportional to the orientation of the pilot's head and, accordingly, his line-of-sight. This beam is detected by a detector (68) which is optically coupled to the light beam and provides line-of-sight information at its ouput. A computer (96) receives the line-of-sight information together with other information and sends it via a cathode ray tube (112) and an optical coupler (14) to a beamsplitter (16) which provides that information to the operator of the vehicle while allowing the operator to see through the beamsplitter (16), thus providing the operator with additional information without obstructing his view.
