ABSTRACT:
A confocal scanning imaging device for viewing an object, includes illumination means including an array of independently addressable microlasers, detection means including an array of detectors for detecting light from an object to which light from the illumination means has been directed. The array of microlasers and the array of detectors are combined into a single array, such as on a single chip, and in a pattern constructed and arranged so that different detectors are adjacent each microlaser so that light from an illuminated object may be directed back to the vicinity of the illuminating microlaser and be detected by the adjacent detector(s). There is optical means for directing light generated by the microlasers onto an object and for directing light from an object so illuminated onto detectors adjacent the illuminating microlaser. The optical means includes a bilens and a matching lens system including two objective lenses. The system is constructed so that the relationships are as follows:
