An enclosure having: a base face that is opaque or translucent to human eyes viewing from outside of the enclosure and transparent to infrared radiation; and at least two flat, orthogonal mounting faces configured to be overlaid respectively on at least two surfaces of walls and ceiling of a room. A thermal imaging apparatus configured to image based on infrared radiation and mounted within the enclosure with a predetermined orientation relative to the base face to have a designed imaging direction with respect to the room when the enclosure is mounted in the room to have the at least two orthogonal mounting faces overlaid respectively on the at least two surfaces.

Imaging apparatuses and enclosures

Systems, methods, and apparatuses having an array of micro mirrors that rotate according to absorbed radiation and reflect light to generate light spots. In a first setting, a processor obtains an image of the light spots, determines positions of the light spots using a computationally efficient but less accurate method to calculate the intensities of radiation directed at the micro mirrors, and provides the calculated radiation. In a second setting, the processor does not determines the position; and the image is transmitted to a separate computing device to determine positions of the light spots using a computationally intensive but more accurate method to calculate the intensities of radiation directed at the micro mirrors. The system can dynamically switch between the first setting and second setting without a need to adjust hardware.

Apparatus and method to adjust sensitivity in measuring electromagnetic radiation using micro mirrors

Systems, methods, and apparatus for providing electromagnetic radiation sensing. The apparatus includes a radiation detection sensor including a plurality of micromechanical radiation sensing pixels having a reflecting top surface and configured to deflect light incident on the reflective surface as a function of an intensity of sensed radiation. In some implementations, the apparatus has equal sensitivities for at least some of the sensing pixels. In some implementations, the apparatus can provide adjustable sensitivity and measurement range. The apparatus can be utilized for human detection, fire detection, gas detection, temperature measurements, environmental monitoring, energy saving, behavior analysis, surveillance, information gathering and for human-machine interfaces.

Apparatus and method for electromagnetic radiation sensing

A two-dimensional pattern comprises a plurality of R-planes each comprising a tiling of a corresponding R-ary block, being a block of radix R integer values, where for each dimension of the pattern, the least common multiple of the sizes of the tiled blocks in that dimension is greater than the size of the tiling that dimension, and any sub-block of a size less than the tiled blocks occurs on a regular grid with the same periodicity as the tiled block for that R-plane. The pattern may be used in determining a position of a location captured in an image by projecting the pattern onto a scene. An image is captured. The method determines from the captured image a sub-block associated with the location and constructs, a unique integer value for each R-plane. The unique integer values from each R-plane are used to determine the location in the image.

Block patterns as two-dimensional ruler

A method for measuring the spatial frequency response (SFR) of an imaging system () including a display device () and an image capture device () is disclosed. The method displays a sequence of displayable test pattern images on the display device, the sequence comprising a first test pattern image and at least two subsequent test pattern images, each of the displayable test pattern images including a test pattern having at least one sinusoidal pattern at one or more spatial frequencies such that a phase shift of the sinusoidal pattern has a plurality of pre-determined values. The displayed images are captured with the image capture device to generate a corresponding sequence of captured test pattern images. The captured test pattern images are then compared with the displayable test pattern images to calculate the SFR at a plurality of image locations in the imaging system at the one or more spatial frequencies.

Measure display SFR using a camera and phase shifting

A method () of demodulating a real two-dimensional pattern () is disclosed. The method () estimates () a quadrature two-dimensional pattern from the real two-dimensional pattern () using a smooth phase only transform having an anti-symmetric phase, such as a spiral phase filter (). A demodulated image is created by combining () the real two-dimensional pattern () and the estimated quadrature two-dimensional pattern.

Demodulation and phase estimation of two-dimensional patterns

A method () of estimating an orientation angle (&#x3b2;) of a pattern in an image () is described. A complex energy operator is applied to the image (). The complex energy operator is defined as &#x3a8;{f}=(D{f})&#x2212;fD{f}. A phase component of the result, which is defined as 2&#x3b2;=arg(&#x3a8;{f}) is determined, from which the orientation angle (&#x3b2;) is calculated. A method () of demodulating a real two-dimensional pattern is also described. A two-dimensional spiral phase filter is applied to the pattern. The result is combined with the original pattern to provide a demodulated image. Furthermore, a method () of estimating a spatial phase of fringe pattern images in a sequence of fringe patterns is disclosed. The fringe pattern images are converted to pure AMFM patterns by removing offsets from each. Contingent analytic images are determined corresponding to each of said AMFM patterns, from which phase differences and phase shifts are determined from dependent pairs. This allows for a spatial phase of the fringe pattern images to be estimated.
