Publication number: 20250116851Abstract: A reimaging lens assembly includes a pentaprismatic optic that includes two reflective surfaces and two refractive surfaces. The reflective surfaces are powered surfaces, and the reflective surfaces may be spherical, aspherical, and/or freeform reflective surfaces. The pentaprismatic optic may receive light from a wide field of view (WFOV), and may change the angle of the output light from that of the input light, for example by 90 degrees. The pentaprismatic optic may be coupled to an image receiver, such as a cooled or uncooled camera. The reimaging lens assembly may include further optical elements between the pentaprismatic optic and the image receiver, such as one or more lenses, filters, and/or cold stops. The lens assembly provides a compact system, with a small number of optical elements, and with desensitized output that reduces image jitter.Type: ApplicationFiled: October 6, 2023Publication date: April 10, 2025Applicant: Raytheon CompanyInventors: Matthew A.

Publication number: 20250067553Abstract: The present disclosure provides an OCT imaging system to reduce or eliminate frequency-domain aliasing artifacts. The frequency is shifted using a carrier frequency to define a sampling range substantially centered on the carrier frequency. An image of the sample is generated from a displayed imaging range that consists of a subset of the frequencies within the sampling range. Furthermore, the system may be configured to determine the carrier frequency such that a Nyquist frequency corresponding to the shifted frequency is extended beyond either an upper or a lower bound of an OCT quality envelope corresponding to the first portion of light. Additionally, the carrier frequency may be determined such that a lower bound of the OCT quality envelope is greater or less than a zero-frequency DC limit.Type: ApplicationFiled: November 12, 2024Publication date: February 27, 2025Applicant: NINEPOINT MEDICAL, INC.Inventors: Eman Namati, Muhammad Al-Qaisi, Matthew A. Sinclair, Benedikt Graf, David Vader

Publication number: 20240369814Abstract: A multi-band/multi-polarization reflective or catadioptric optical system yields differing effective focal lengths (EFLs) per band/polarization. This approach could be used to create an imaging system, for example. In such case, a sensor (imager, spectrometer, diode, etc.) is located at the one or more focal planes. On the other hand, it could also be used to create a projecting system or hybrid projecting and imaging system by locating an emitter such as an LED, laser, etc.) at the image or focal plane. The system employs polarizers and/or dichroic coatings nano patterns to create different focal lengths and/or fields of view using the same mirrors and/or lenses by, for example, including at least one dichroic coating optically in front of at least one additional mirror to separately reflect the different bands or polarizations.Type: ApplicationFiled: July 15, 2024Publication date: November 7, 2024Inventors: Matthew A.
