摘要： Providing for a fixed focus optical system exhibiting extended depth of field is provided herein. By way of example, a compact and fast optical system that yields an asymmetric modulation transfer function (MTF) is disclosed. In some aspects, the asymmetric MTF results in extended depth of field for near field objects. Such a response can be particularly beneficial for small handheld cameras or camera modules having high resolution. According to some disclosed aspects, the resolution can be about 8 mega pixels. Additionally, the optical system can comprise four lenses in one aspect and five lenses in another, while remaining below about 5.3 mm total track length (TTL) for the respective systems. In at least one application, the disclosed optical systems can be employed for a high resolution compact camera, for instance in conjunction with an electronic computing device, communication device, display device, surveillance equipment, or the like.

摘要翻译：本文提供了提供展现景深的固定聚焦光学系统。作为示例，公开了产生非对称调制传递函数（MTF）的紧凑且快速的光学系统。在一些方面，非对称MTF导致近场物体的景深扩大。这样的响应对于具有高分辨率的小型手持相机或相机模块可能是特别有利的。根据一些公开的方面，分辨率可以是大约8兆像素。此外，光学系统可以包括一个方面中的四个透镜和另一个方面的五个透镜，而对于各个系统，光学系统的总轨道长度（TTL）保持在5.3mm以下。在至少一个应用中，所公开的光学系统可以用于例如结合电子计算设备，通信设备，显示设备，监视设备等的高分辨率小型照相机。

摘要： A fixed optical unit (200) includes one or more fixed optical elements (202). The optical unit has a modulation transfer function (MTF), for a given object distance and a given spatial frequency associated with an imaging surface of an image sensor disposed at a selected distance from the fixed optical unit, which varies with object distance such that the MTF is at a maximum at a selected image distance, decreases from about the maximum MTF to below a predefined threshold value within a first range of positive focus shifts corresponding to image distances less than the selected object distance, and decreases from about the maximum MTF but remains above the predefined threshold value over a second range of negative focus shifts corresponding to image distances greater than the selected object distance. The second range of negative focus shifts is larger than the first range of positive focus shifts.
摘要翻译：固定光学单元（200）包括一个或多个固定光学元件（202）。光学单元具有对于给定物体距离的调制传递函数（MTF）和与设置在距固定光学单元选定距离的图像传感器的成像表面相关联的给定空间频率，该距离随物体距离而变化， MTF在所选择的图像距离处处于最大值，在对应于小于所选对象距离的图像距离的正焦点偏移的第一范围内，从约最大MTF减小到低于预定阈值，并且从约最大MTF减小，在对应于大于所选对象距离的图像距离的负焦点偏移的第二范围内，保持在预定阈值之上。负焦点偏移的第二范围大于正焦点偏移的第一范围。
