The optical advantages of curved focal plane arrays.
The design of optical systems for digital cameras is complicated by the requirement that the image surface be planar, which results in complex and expensive optics. We analyze a compact optical system with a curved image surface and compare its performance to systems with planarimage surfaces via optics analysis and image system simulation. Our analysis shows that a curved image surface provide...
متن کاملOptical Detectors for Focal Plane Arrays §
The paper presents progress in optical detector technologies during the past 25 years. Classification of two types of detectors (photon detectors and thermal detectors) is done on the basis of their principle of operation. The overview of optical material systems and detectors is presented. Also recent progress in different technologies is described. Discussion is focused mainly on current and ...
متن کاملMeeting the Optical Requirements of Large Focal-Plane Arrays
Technological advances will allow the placement of many Terahertz detectors at the focal plane of a single telescope. For a telescope of a given diameter and wavelength of operation, there is a limit to the number of usable detectors imposed by diffraction and optical aberrations. These effects can be ameliorated through an optical design where the magnification of the telescope’s secondary mir...
متن کاملMosaicked Multispectral Focal Plane Arrays
A mosaicked sensor is a monolithic array of many sensors, arranged in a geometric pattern. In the commercial digital color camera market, the mosaicked color filter array (CFA) technique is widely used, in which instead of using three charged coupled devices (CCDs) to capture the red, green, and blue spectral bands for each pixel, each pixel is associated with just one device covered by an opti...
متن کاملFull-Sampling Focal Plane Arrays
The eeciency of single dish mapping and synthesis array mosaicing can be increased by completely sampling the information in the antenna's focal plane. This requires a densely packed array of electrically small elements. Each telescope beam is formed with a weighted combination of signals from seven or more elements. This has the added advantage of correcting for large scale reeector distortion...
