Abstract: A multi-telescope imaging system includes a first telescope and a second telescope, each telescope having an input line of sight, a ray path that is incident upon a focal surface imaging location at a non-normal angle of incidence, and a shutter lying on the ray path. A single common sensor lies at the focal surface imaging location, such that the first-telescope ray path and the second-telescope ray path are alternatingly incident upon the same focal surface imaging location of the sensor. A shutter controller alternatingly opens and closes the two shutters, so that the sensor alternatingly views the scenes imaged by the two telescopes.

Abstract: A system and method for simultaneous imaging of both infrared and millimeter wave radiation. The novel optical system (10) includes a primary mirror (20), a Mangin secondary mirror (30) positioned to receive energy reflected from the primary mirror (20), and an immersion lens (40) for focusing energy received from the Mangin mirror (30). In the illustrative embodiment, the primary mirror (20) and Mangin mirror (30) are arranged in a Cassegrain configuration. Central to this invention is the use of a negative power refractive Mangin mirror (30) as the Cassegrain secondary mirror, so that the field curvature of the secondary mirror (30) and immersion lens (40) can be made to cancel. The immersion lens (40) effectively decreases the wavelength of the millimeter wave radiation, allowing a smaller detector to collect the same amount of radiation as would a larger detector in air. In the illustrative embodiment, the system (10) further includes a detector array (52) placed in intimate contact with the immersion lens (40).

Abstract: A system and method for focusing infrared detectors operable at cryogenic temperatures. The invention includes a sensor (10) for detecting electromagnetic energy comprising a first detector (14) operable over a first temperature range and a predetermined number of auxiliary detectors (12) operable over a second temperature range, wherein the auxiliary detectors (12) are adjacent to and in the same optical plane as the first detector (14). In the illustrative embodiment, the energy is infrared or visible light, the first temperature range is a range of cryogenic temperatures, and the second temperature range is a range of ambient temperatures. The first detector (14) is a focal plane array and the auxiliary detectors (12) are uncooled detector arrays. In the preferred embodiment, the focal plane array (14) and the uncooled detectors (12) are disposed on a common substrate. In accordance with the teachings of the present invention, the novel sensor (10) can be used to focus an optical system at cryogenic temperatures. The inventive method includes illuminating energy onto the sensor (10) through the optical system at ambient temperatures and then adjusting the position of the sensor (10) until maximum illumination is received by the auxiliary detectors (12). This determines the location of the focal plane of the system at ambient temperatures. The location of the focal plane at cryogenic temperatures can then be calculated using the location of the focal plane at ambient and a model of the thermal characteristics of the system.

Abstract: A multi-slit spectrometer is combined with a two-dimensional detector array to enable simultaneous spectral analysis of several objects, improving the signal-to-noise ratio of multispectral imagery. The multi-slit spectrometer includes a multi-slit structure defining a plurality of parallel thin slits, and a first lens for directing object light onto the multi-slit structure. A second lens collimates and directs light which has passed through the slits of the multi-slit structure onto a light dispersing element such as a dispersing prism or a diffraction grating. A third lens focuses light which has passed through the light dispersing element onto the two-dimensional detector array at an image plane. A two dimensional detector array of detector elements is placed at the image plane. The slits are separated by a separation distance equal to an integral multiple of the detector width dimension, where the multiple is equal to (N times the number of slits) plus or minus one, where N is an integer. In an airborne sensor, a mirror which rotates at an angular velocity related to the velocity of the airborne platform directs object light onto the first lens, freezing the image from one or more objects onto the multi-slit structure for an integration time.

Abstract: A corrector mirror folds the optical path between the objective and relay portions of a three-mirror anastigmat. The corrector mirror is a non-powered mirror having a nominally flat but higher order aspheric surface. By placing the corrector mirror between the objective portion and an intermediate image formed by the objective portion, the field offset of the anastigmat can be significantly increased. A large field offset makes the off-axis anastigmat ideal for use with an on-axis dewar for infrared imaging applications.

Abstract: A wide angle large reflective unobscured system includes a primary reflective element for receiving a broad range of energy, a secondary reflective element for reflecting the energy from the primary reflective element to reimage a virtual entrance pupil at a real aperture stop. A beamsplitter element is provided for reflecting a first portion of the energy, such as visible energy, to a first tertiary reflective mirror, while transmitting a second portion of the energy, such as IR light, to a second tertiary reflector. Each tertiary reflector is capable of focusing the received energies to dual focal planes wherein a compact detector array assembly can convert the images to electronic signals.

Abstract: An optical apparatus monitors the entire panorama in low resolution and simultaneously monitors a selected portion of the panorama in high resolution. For the panoramic portion of the apparatus, a mirror having a convex surface of revolution with a hole therein is used. The higher resolution part of the apparatus uses a pointing mirror positioned above this hole. The panoramic and higher resolution views are imaged through lenses or optical components onto a detector. The panoramic view is imaged onto the detector as an annulus of light in which either higher or lower elevational angles of the panorama are imaged further away from the detector's center depending upon how the convex mirror is configured. In this way, the resolution of that portion of panorama that is imaged further away from the detector's center is enhanced. The higher resolution view is imaged to the center of the annulus. Thus, both panoramic and higher resolution portions of the desired scene share the same detector array without interruption, interference, or overlap.
