Compact FOV Multiplexing Telescope

In the field of imaging, there has been a perennial need for methods and devices that are able to capture detailed images covering extended fields of view without compromising on quality or resolution. Conventional imaging devices often struggle to balance these aspects, hence the need for innovative improvements within the field. Standard imaging sensors are limited by their field of view and image resolution, especially when the objective is to capture images from an extended field with high spatial resolution. The high demand for such enhanced imaging, especially in disciplines such as surveillance, mapping, aerospace, robotics, and medicine, combined with the limitations of existing approaches, creates the need for a superior solution. The problem with conventional imaging techniques is that they must strike a balance between the size of the field of view, image quality, and hardware complexity. Increasing the field of view or resolution typically involves using more or larger sensors, thereby adding significant cost and complexity to the system.

Technology Description

This technology involves devices and methods for multiplexed imaging. These devices can concurrently direct identical-spectrum light from multiple image channels onto a single image sensor, resulting in a multiplexed image on the sensor. Notably, each image channel collects light from various sections of an extended field of view or from the same portion through distinct perspectives. In addition, the device can come with one or more encoders responsible for encoding light from the channels prior to detection. These techniques and devices also have the ability to disambiguate a captured multiplexed image to create separate images for each image channel. What sets this technology apart is its capability to cover the extended field of view at a high spatial resolution with only a single small-format imaging sensor. The technology can also generate three-dimensional or stereo images with full sensor resolution. Ensuring high resolution while achieving a broad field of view, even with a single small imaging sensor, marks the uniqueness of this technology.
