Provided is an image forming method including a step of imagewisely applying, onto a base material by an inkjet method, at least two inks containing a polymerizable liquid crystal compound, a chiral compound, and a polymerization initiator and having reflection wavelengths different from each other, such that the total application amount of the inks provides an image area ratio of 50% or more in an image forming region.

The present invention relates to target acquisition and related devices, and more particularly to telescopic gunsights and associated equipment used to achieve shooting accuracy at, for example, close ranges, medium ranges and long ranges at stationary and moving targets.

An optical device 10 comprises an objective lens 11 defining a focal plane FP and an eyepiece 12 spaced apart therefrom, defining an optical axis OA therethrough. The optical device 10 comprises an optical member 13 having a first planar face 14, arranged on the optical axis OA proximal the focal plane FP, wherein the first planar face 14 is arranged to oppose the objective lens 11. The optical device 10 comprises a filter assembly 100 comprising a first notch filter 101 arranged to attenuate transmission of electromagnetic radiation having a first wavelength .sub.1, wherein the first notch filter 101 is arranged in front of the optical member 13. The first notch filter 101 is arranged at a first oblique angle .sub.1 to the optical axis OA whereby, in use, incident electromagnetic radiation having a predetermined wavelength .sub.i propagating along the optical axis is reflected by the first notch filter 101 away therefrom, wherein the first wavelength .sub.1 and the predetermined wavelength .sub.i are different. In this way, retro-reflection of the incident electromagnetic radiation towards a source thereof is reduced, thereby better detection of the optical device 10.

An augmented-reality device is provided. The augmented-reality device is configured to retrieve security information for a plurality of persons at respective security checkpoints. In addition, the augmented-reality device is configured to concurrently display the security information for each of the plurality of persons on an augmented-reality display. Security information is superimposed on or adjacent to each of the plurality of persons located at respective security checkpoints, the display configured to maintain visibility of the security checkpoint.

A technical concept of the present invention provides: a curved pattern marker capable of improving the precision of position detection and reducing size; and an optical tracking device including the marker. The marker comprises: a first lens unit, which has at least one lens having an incident surface, emits incident light within a target range, and is formed such that a light parallel to an optical axis among the incident light is vertically incident on the incident surface; a pattern unit having a curved pattern formed therein; and a second lens unit arranged between the first lens unit and the pattern unit, and adjusting the light emitted from the first lens unit such that the light is focused on the curved pattern.

A scope turret including a dial assembly that is configured to adjust point of aim optics of a scope is disclosed. The turret may include an adjustable stop assembly that prevents the dial assembly from rotating in one direction. The adjustable stop assembly may include a traveler, a nut assembly, and a bolt. The adjustable stop assembly may be internally-adjustable or externally-adjustable. The dial assembly may include an engagement mechanism. The engagement mechanism may include a button that is slidable between an engaged position and a disengaged position of the engagement mechanism. The turret may further include a locking mechanism that selectively prevents the dial assembly from rotating in any direction.
