Abstract
패턴 ERG(RERG) 투사기는 투사 비임을 발생시키기 위한 간섭성 광원(32), 투사 비임을 교호하는 ERG 간섭 패턴으로(선택된 공간 및 교호 주파수로)변조시키기 위한 변조 광학기(34), ERG 간섭 패턴을 선택적으로 분할하기 위한 분할 광학기(35), 및 투사 비임이 동공을 통과한 다음 분기하여, 원주변 밖의 전방 망막을 포함하는 전체 망막 시야 상에 투사되도록 투사 비임의 초점을 맞추기 위한 상형성 광학기(36)로 구성된다. RERG 시험 프로그램의 전체 망막을 선택적으로 조사하고 망막지도를 전개하기 위하여 사용할 수 있으며, …RERG 자료는 망막 신경절 세포 시력과 관련있고, 그러므로 녹내장 및 그외 질병에 의해 야기된 망막 변성을 진단하고 감시하는데 유용하다.Pattern ERG (RERG) projectors have a coherent light source 32 for generating a projection beam, modulation optics 34 for modulating (with selected spatial and alternating frequency) alternating projection beams, ERG interference pattern Splitting optics 35 for selectively dividing the beam, and image forming optics for focusing the projection beam such that the projection beam passes through the pupil and then branches to project over the entire retinal field of view including the outer retina outside the periphery. Group 36. The RERG test program can be used to selectively examine the entire retina and develop retinal maps,… RERG data are related to retinal ganglion cell vision and are therefore useful for diagnosing and monitoring retinal degeneration caused by glaucoma and other diseases.

제1도는 본 발명의 망막-투사 시스템의 기능 블럭 선도이다.1 is a functional block diagram of the retina-projection system of the present invention.
제2A도는 ERG 간섭 패턴을 생성하기 위한 전단 간섭계를 포함하는, 망막의 전체 시야 상에 ERG 패턴을 투사할 수 있는 PERG 투사기로서 망막-투사시스템의 적용을 예시한다.2A illustrates the application of the retina-projection system as a PERG projector capable of projecting an ERG pattern over the entire field of view of the retina, including a shear interferometer for generating an ERG interference pattern.
제2b도는 전체 망막의 선택 구획이 조사되도록 하는, PERG 투사기로부터 ERG 패턴의 에시적인 분할을 예시한다.FIG. 2B illustrates the illustrative segmentation of the ERG pattern from a PERG projector, allowing the selective compartment of the entire retina to be irradiated.
제3도는 본 발명에 따른 PERG 투사기를 사용하여 컴퓨터 제어 PERG 시험하에 수행하기 위한 PERG 시스템의 기능 블럭선도이다.3 is a functional block diagram of a PERG system for performing under computer controlled PERG testing using a PERG projector in accordance with the present invention.
