    Abstract: An optical navigation device for use with mobile telephones and the like is disclosed, which has a reduced height as compared with current designs. The navigation device comprises a laser such as a VCSEL laser, an exposed user surface and two other surfaces that provide for total internal reflection of the incident laser beam. The surfaces are constructed with shallower than normal angles, preserving the basic functionality of the device while reducing the height.

    Abstract: A radiation sensor includes first and second pixels with a radiation absorption filter positioned over the first pixel and an interference filter positioned over both the first and second pixels. The combined spectral response of the absorption filter and the first pixel has a first pixel pass-band and a first pixel stop-band. The spectral response of the interference filter has an interference filter pass-band which is substantially within the first pixel pass-band for radiation incident on the interference filter at a first angle of incidence, and substantially within the first pixel stop-band for radiation incident on the interference filter at a second angle of incidence greater than the first angle of incidence.

    Abstract: An image sensor includes a pixel array and an image sensor objective optical element. The element is formed by a lenslet array. Each lenslet in the array directs incoming radiation onto a different specific pixel or sub-array of pixels in the pixel array. The lenslets in the array are shaped such that fields of view of next-but-one neighboring ones of the lenslets (i.e., two lenslets spaced from each other by another lenslet) do not overlap until a certain object distance away from the lenslet array.

    Abstract: PSF coding has become well known in recent years. Although it enables significant increases in the depth of field, defocus introduces artifacts in images that are a major detraction from the final image quality. A method is described that enables the deduction or defocus and consequently the removal of these artifacts. The principle of the disclosed techniques involves iteratively adjusting the restoration algorithm according to a chosen image metric and choosing the defocus parameter that yields the image the lowest level of artifact.

    Abstract translation: 近年来，PSF编码已经成为众所周知的。 虽然它能够显着提高景深，但散焦会在图像中引入伪像，这是最终图像质量的主要障碍。 描述了一种能够减少或散焦并因此去除这些伪影的方法。 所公开技术的原理涉及根据所选择的图像度量迭代地调整恢复算法，并且选择产生图像最低级别的伪影的散焦参数。
