Research progress and perspective of hyperspectral image projectors

Abstract

As a new hyperspectral image projection technology developed in recent years, hyperspectral image projectors(HIP) provides an economical, practical and effective solution for the detection, evaluation and nonlinear calibration of hyperspectral imager. HIP, based on the spatial light modulation technology used in DMD and LCD, is capable of projecting an arbitrary spectrum into each spatial pixel to simulate a realistic scenes. We describes the concept of a generic hyperspectral image projector, and presents an overview of its applications in a number of areas. The possibilities of development direction in the future are proposed.
