The aberration-free characteristic endows the double-grating Offner stretcher with the
advantages of good beam quality and perfect-dispersion-match with conjugated Treacy …

Optical edge detection, a part of image processing, plays an important role in extracting
image information used in optical analog computation. In this Letter, we raise a new way to …

In general, k lenses with different materials can achieve at most (k+ 1) color correction (k≥
2). A superachromat containing three lenses is designed to achieve five-color correction in …

The rapid development of microsatellites necessitates optical systems with smaller sizes and
more sharpening imaging. However, with the difficulty in lens design within confined …

With the continuous improvement of imaging performance requirements, the design of
imaging systems has become increasingly complex, making it more difficult and expensive …

Due to the difficulty of correcting chromatic aberration (CA) in telephoto cameras, recent
studies have combined image algorithms with simple optical structures, such as single …

A novel design of double chirped pulse amplification laser systems implementing a
combination of negatively and positively chirped pulse amplification is proposed for the first …

Pulse front distortion occurring in lenses can broaden the temporal profile of the pulse at
focus and therefore decrease the focused intensity, especially for large-aperture …

Multiple lenses are used in most modern imaging systems to reduce deviations from the
perfect optical imaging, which also results in a significant increase in prices. Computational …
