“…Several teams have proposed various architectures that differ in the way of dividing the information contained in the observation scene. The scene can be spatially split into various channels [6,[8][9][10][11], each channel imaging a small part of the scene. The high-frequency content of the scene can be split into different channels also [12,13].…”

We present an original and compact optical system inspired by the unusual eyes of a Strepsipteran insect called Xenos peckii. It is designed for a field of view of 30°and is composed of multiple telescopes. An array of prisms of various angles is placed in front of these telescopes in order to set a different field of view for each channel. This type of camera operates in the [ 3 − 5 μm] spectral bandwidth and is entirely integrated in a Dewar in order to maximize its compactness. Experimental images are presented to validate this design.

“…1 Novel approaches include the use of the wavefront coding method to simplify the lens systems 2,3 and multichannel objectives. [4][5][6][7][8][9][10][11] For fabrication and integration advantages, the multichannel objectives are made very thin using small optical channels. However, the angular resolution of these systems is limited and superresolution techniques, such as the thin observation module by bound optics method, 5 are required.…”

Field curvature correction in multichannel miniature imaging systems suited for wafer-level production

Abstract. Using multiple optical channels increases the number of design possibilities for the objectives of mobile imaging devices. For easy waferlevel fabrication, we start from a single optical element-a monocentric plano-convex lens. The quality of the areal image is used to select the size of the field of each channel. Each channel optics is axially positioned to reduce the effect of the image field curvature. The resulting device has a small number of channels and it images a full field of view of AE40 deg with an f -number of 3. Details of the optical design, of the fabrication process, and of the device performance are reported. © The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.

“…Some are inspired by the optical imaging systems of invertebrate animals. [1][2][3] Compound apposition and superposition eyes are two broad categories. In this research, a lenslet array serves as the basis for a thin, compound imaging apposition optic that, owing to its multichannel nature, admits a diversity of spectral filters and linear polarizers.…”

Modeling and simulation of a spectro-polarimetric lenslet array imager

Abstract. A new, economical, lenslet-array-based imaging sensor design is proposed, simulated, and analyzed. In this investigation a bare lenslet array model is first developed in Code V®. The results show that, as expected, intolerable optical cross-talk is present in this simple system. This problem has been addressed in previous systems via the inclusion of a physical image separation layer. The alternative system proposed here to alleviate crosstalk involves the introduction of both polarizers and spectral filters. As a consequence this simple system design also provides spectro-polarimetric resolution. Simulations were developed in order to analyze the system performance of two designs. The simulation results were analyzed in terms of a measure of signal-to-noise ratio (SNR) and in terms of an en-squared energy that includes all subimages. The results show that a design employing only a few spectral filters suppresses crosstalk for objects of small angular extent but does not suppress crosstalk to a tolerable level for 2π steradian illumination, as evidenced by SNR less than one. However, the inclusion of more spectral filters results in a spectropolarimetric thin imager design that suppresses crosstalk and provides finer spectral resolution without the inclusion of a signal separation layer.
