The device comprises at least one light source, non-imaging light collimator (NILC), at least one first and second condenser, a ball lens and at least one galvo-mirror. The light source is one of light emitting diode (LED) and organic LED (OLED), which emits light of a predefined wavelength. The NILC collimates the light emitted by the at least one light source, the at least one first condenser produces a focused light beam using the collimated light. The at least one second condenser produces light spots, with a diameter in terms of microns, using the focused light beam from the at least one first condenser. The ball lens collimates the light spots, which is steered by the galvo-mirror to focus on a target area.

Abstract: Non-tactile and non-evasive tonometer utilizing air flow with a definite amount of pressure to the eye and a mechanism to deflate the thin foil set that is placed near to eye ball such that re-bounded air hits on it. The mechanism involves acquiring or capturing then the images of the known pattern marking on thin foils both before and after deflating process due to rebounded air. On evaluating the deformation of the pattern appearing in the images obtained before and after air flow and calibrating the deformation with respect to size, translation, rotation and scaling parameters due the different pressure level that hits the eye ball and that rebounds on to thin foils, we arrive at a scheme of measuring the intraocular pressure of human eye. This intraocular pressure is used as a parameter for the ophthalmologist to diagnose glaucoma impairment of human beings.

Abstract: The present disclosure relates to method and apparatus for image recovery and image correction. In an embodiment, the present disclosure relates to recovering images that are occluded due to some material in the optical path while capturing the images. The detection of noisy region is performed by taking the residual image between the images yielded by large sized and small sized Gaussian window smoothening filters on red, green and blue channels. The recovery of the image that alleviates the noise is obtained by point-wise multiplication of the above said residue image with a suitably synthesized Gaussian distributed co-efficient of same size.

Abstract: The embodiments herein provide a system and method for detecting and capturing a focused image. The system comprises of an image capturing unit, edge detection unit and a focusing unit. The image capturing unit obtains plurality of images sequentially. The edge detection unit identifies region of interest in each of the obtained images and calculates edge strength value for the identified regions. The edge detection unit determines peak edge value from the edge strength values. The edge strength value quantifies degree of focus in the identified region. If the identified region is more focused, the number of edges is relatively more when compared with out-of-focus region. The peak edge value indicates that the identified region is well focused. The focusing unit causes the image capturing unit to capture focused image when the edge strength value reaches a predefined value of the peak edge value.

In addition, the image filtering for enhancing image quality is enhanced by several variations of data adaptive guided image filtering and adaptive window sizes for guided image filtering techniques.
