摘要：
the present invention relates to a portable, lightweight, digital imaging device that uses a slit-scanning arrangement to obtain an image of the eye, in particular the retina. the raster layout reduces the amount of target area illuminated in a moment, thereby reducing the amount of undesired light scattering and providing a superior contrast image. a detection array receives the light dispensed from the retinal plane and produces an image. the device is operable under battery power and ambient light conditions, such as outdoor or ambient lighting. the device is non-contact and does not require the pupil of the eye to be dilated with drops. the device can be used by personnel who do not have specialized eye training, such as emergency personnel, pediatricians, general practitioners or volunteers, or otherwise unskilled screening personnel. images can be viewed on the device or transmitted to a remote location. the device can also be used to provide images of the anterior segment of the eye or other small structures. visible light at wavelength is not required to produce images of more important structures in the retina, thus increasing the comfort and safety of the device. forming a fluorescent image with the same focus, flexible and of moderate cost, multiplying scattered light images and better defining the image are still possible features with the device.a presente invenção refere-se a um dispositivo portátil, leve, de formação de imagem digital usa uma disposição de varredura de fenda para obter uma imagem do olho, em particular a retina. a disposição de varredura reduz a quantidade de área alvo iluminada em um momento, assim, reduzindo a quantidade de dispersão de luz inde-sejada e proporcionando uma imagem de contraste superior. uma disposição de detecção recebe a luz dispensada do plano retinal e produz uma imagem. o dispositivo é operável sob energia de bateria e condições de luz ambiente, como iluminação exterior ou ambiente. o dispositivo é de não contato
