The current measurement system of surface scattering rate applied in laser protective materials has the defects of low accuracy, discontinuous diagnosis region and narrow infrared measuring waveband. In order to make up for these shortcomings, a high

Aiming at addressing the vulnerability of the infrared imaging opto-mechanical system to stray radiation interference caused by an external laser, a new method with a broadband and high-absorptivity ceramic coating on the inner wall of the system is

The expressions of the Seidel aberration theory are comparatively simple and easy to use due to its characteristics and prerequisites. Meanwhile, the effective range of the theory is limited also due to its prerequisites. The possibility for enlargin

The revisions of enlarging all the aberrations related to aperture to the seventh order for the Seidel aberration theory have been proposed in this paper. The practice of the revised theory in the range of small viewing field and large aperture (for

A new type of Galilean binoculars is presented. The objective lenses are composed of a cemented doublet and a positive meniscus, and the eyepiece is a negative thick meniscus. In addition, all of the surfaces except the gluing surface are concave tow

The spherical aberration coefficient (SAC) can be divided into : intrinsic and derivative coefficients. The former occurs on certain boundaries without incident beam aberration, and the latter is the variant of spherical aberration (SA) which is caus

The relationship between aberration and the aberration coefficient is the basic formulation in the field of aberration theory. The Seidel's formulations can only be used in the case of low performance (small aperture and small field), so that a set o

Accurate knowledge of the relative image irradiance is important in the design of some optical instruments, e.g., IR systems, where it determines the apparent temperature of the object, and camera systems employing irregular-shaped aperture stops or
