Discrete light fiber inputs for high powered image projector display systems are disclosed herein. Various embodiments disclosed herein may employ a bundle of light fiber inputs, a diffuser and reducing relay optic to convert the fiber input array into a smaller pattern of spots that may be interfaced to a projector display system that may perform light recycling. Many embodiments herein may facilitate higher power laser light for illumination and, possibly, recycling. In these embodiments, laser fibers may be individually collimated and illuminate a diffuser. The diffuser spots may be then imaged through a common path relay that can be resized to allow room for the individual lasers and collimation lenses. The diffuser spots may be imaged through holes in a mirror that is on the input side of an integration rod which recycles the light.

An optical axis alignment method may include the steps of taking an image of a lens holder and a holder base to obtain contour information before laser irradiation, detecting location information about a light path of a light beam which exits from a collimating lens, adjusting the position of the collimating lens by plastically deforming via laser irradiation, taking an image of a contour of a lens holder and a base member to obtain new contour information and detecting new location information about a light path of a light beam which exits from the collimating lens. If the accuracy is not within the predetermined allowable limits, the laser irradiation condition is corrected based on the contour information and/or the location information obtained both before and after the laser irradiation and the lens position adjustment is repeated.

In an imaging apparatus including a substrate having an imaging device mounted thereon, a frame fixed on the substrate, and a seal glass, wherein the seal glass and the frame are bonded together using a sealing resin to provide a structure that encapsulates the imaging device, a cured material resulting from curing of the sealing resin has a regular reflectance of 3% or less, and a diffuse reflectance of 30% or less. This can reduce or eliminate occurrence of ghost and flare in the imaging apparatus.
