February 1, 2018 – JAI announced the addition of a trilinear color line scan camera to its Sweep Series camera family. The SW-4000TL-PMCL features a custom CMOS trilinear imager with 4K (4096 pixels) resolution and a full line rate of 66 kHz for 24-bit non-interpolated RGB output. The SW-4000TL-PMCL trilinear camera has been combined with a broad set of features to give designers an attractive alternative for applications not requiring the precision provided by prism cameras.
For example, the custom CMOS imager features six separate lines of 7.5-micron pixels with two lines each of red, green, and blue pixels. This arrangement makes it possible for the SW-4000TL-PMCL to provide horizontal binning, vertical binning, or both. Furthermore, the sensor’s readout architecture combines the readout of two pixels through a single diffusion node to double the signal without increasing noise, enabling the binning process to increase sensitivity.
Another feature is the built-in color conversion capability that allows the SW-4000TL-PMCL to provide native HSI or CIEXYZ color output, in addition to offering conversions from standard RGB to the sRGB or Adobe RGB color spaces, or even to a user-defined custom RGB conversion matrix.
The SW-4000TL-PMCL features spatial compensation and tilted view correction functions to maintain proper synchronization and alignment of the R, G, and B channels. In addition, the camera features four separate input lines plus built-in algorithms to support direct connection from up to two rotary encoders.
The direct encoder connection capability can also be used to daisy-chain multiple SW-4000TL-PMCL cameras to each other in multi-camera setups, and can be used to automatically detect if the scan direction changes. If a reversal of direction is detected, the spatial compensation can be adjusted for the correct line sequence. This feature is useful for scenarios such as when a reciprocating slide table is being used as the method of conveyance.
Additional standard features include gain and black level adjustment, manual or automatic white balancing, shading correction, PRNU and DSNU correction, and timestamping of line data.
The SW-4000TL-PMCL utilizes a GenICam and Gen-CP-compliant Camera Link interface with Mini CL connectors to output line data. Base, Medium, Full, or Deca configurations are supported, depending on the bit depth and line rate required. 3 x 8-bit and 3 x 10-bit output can be selected.
Power can be provided via the Camera Link interface or with a separate power supply connected to the camera’s 12-pin Hirose connector.
Two different lens mount options are available – a Nikon F-mount or an M42x1 mount with a 16 mm flange back distance.
