A method for the design of an unobscured reflective zoom system with three mirrors is described. This method applies the......

Toroidal surface and biconic surface are employed increasingly, however their profile cannot be null tested easily for t......

A real-time two-dimensional (2D) triangulation range finder is presented, which is composed of two linear complementary ......

To improve ophthalmic adaptive optics (AO) speed and compensate for ocular wavefront aberration of high temporal frequen......

Analysis of glass homogeneity using the attaching interferometric data model neglects body distribution. To improve anal......

In this Letter, a 116-actuator deformable mirror (DM) was used to correct the wavefront distortion in a 10.7 J, 10 Hz ne......

A modified asymmetrical Czerny-Turner arrangement with a fixed plane grating is proposed to correct aberrations over a b......

Adaptive optics (AO) systems greatly improve the resolution of retinal imaging instruments by actively correcting ocular......

We present linear conjugated combined aberration modes with a concentric pupil diameter of 4 mm. The combinations are ac......
