MEMS Actuator Images
Here are a number of images of various mems devices.

Metallurgical Imaging
Wavefront Coding™ Metallurgical imaging produces images that have sharper and more clear features than traditional imaging. This increase in sharpness can greatly assist in applications such as MEMs.

  Hoffman Imaging
Wavefront Coding™ Hoffman imaging produces images with characteristic Hoffman intensity shading of phase objects and a very large depth of field and at real time rates. Hoffman Modulation Contrast imaging is mainly used to produce three dimensional appearing images through birefringent plastc culture chambers. These particular images are of mouse embryos.

  Fluorescence Imaging
High magnification microscopy systems can have a depth of field on the order of microns. This depth of field is often too small to image the full depth of objects being studied. A confocal imaging system can image with a large depth of field by scanning a large number of object planes. But, the confocal method requires large total exposure times and increased bleaching of the fluorescent dyes. Wavefront Coding™ provides a depth of field and spatial resolution comparable to a confocal imaging system with only a single image from a single image plane.

  High Magnification Widefield Imaging
High magnification microscopy systems can have a depth of field on the order of microns. This depth of field is often too small to image the full depth of objects being studied. A confocal imaging system can image with a large depth of field by scanning a large number of object planes. But, the confocal method requires large total exposure times and increased bleaching of the fluorescent dyes. Wavefront Coding™ provides a depth of field and spatial resolution comparable to a confocal imaging system with only a single image from a single image plane.

 
2D Bar Code Reading
Extended depth of field through Wavefront Coding™ provides a much larger depth of field, or depth of focus, than is possible from a traditional optical system without stopping down the aperture or increasing the f-number.

  Qualitative Extended DOF Imaging
The depth of field of an optical/digital imaging system can be independent of aperture size or f-number with CDM Optics' Wavefront Coding™ technology. A large aperture (or small f-number) system can have the depth of field of a very small aperture (or large F-number) system. These images give a quick quantitative look at optical/digital extended depth of field.

  3-Color Imaging
Wavefront Coded™ extended depth of field imaging systems can operate in grayscale or color imaging systems. The color of the extended depth of field image is identical to the small depth of field traditional imaging system.

 
Macro Imaging
Macro imaging systems often have a depth of field that is too small to image an entire object clearly. By applying Wavefront Coding™ to a 3X macro imaging system, the system images with a very large depth of field with no loss of resolution or sharpness.

  Biometric Imaging
Biometric imaging is a method of identification or verification based on unique physical characteristics such as fingerprints, retinal or iris images, etc. Due to the relatively large magnifications used, the depth of field with traditional imaging systems is often very small. Wavefront Coding™ can greatly increase the depth of field and increase the light gathering ability of these systems.

  Achromatic Imaging
Wavefront Coding™ is a general technique that can be used to correct for a number of on-axis lens aberrations in order to reduce the cost of the imaging system, increase the performance, or both. The aberrations that can be corrected include temperature related aberrations, such as focus shift due to temperature which is commonly found when using plastic lens elements. The example shown demonstrates the technology's ability to control focus shift as a function of color, or axial chromatic aberration.

  Wide Field of View Singlets
The cost of digital imaging systems can be greatly reduced without sacrificing image quality by using CDM Optics' optical/digital Wavefront Coding™ technology. The imaging task can be shared by both optics and signal processing. A wide field of view singlet is one example where the majority of the costs are shifted from optics to the processing.

  Antialiasing
Wavefront Coding™ technology, incorporated into a lens system as an antialiasing optical filter, replaces quartz plates with a superior performing and lower cost solution. Also, Wavefront Coding™ technology provides adjustable spatial frequency bandwidth. This image shows an MTF comparison between a fixed bandwidth quartz filter and a Wavefront Coded™ filter.

  Ray Diagrams
Ray diagrams provide a visual representation of utilizing Wavefront Coding™ technology to extended the depth of field of an imaging system. A comparison between traditional imaging and Wavefront Coded™ imaging illustrates how sensitivity to misfocus is minimized by Wavefront Coding™.
